2 | Advanced Linux Sound Architecture - Driver | |
3 | ========================================== | |
4 | Configuration guide | |
5 | ||
6 | ||
7 | Kernel Configuration | |
8 | ==================== | |
9 | ||
10 | To enable ALSA support you need at least to build the kernel with | |
11 | primary sound card support (CONFIG_SOUND). Since ALSA can emulate OSS, | |
12 | you don't have to choose any of the OSS modules. | |
13 | ||
14 | Enable "OSS API emulation" (CONFIG_SND_OSSEMUL) and both OSS mixer and | |
15 | PCM supports if you want to run OSS applications with ALSA. | |
16 | ||
17 | If you want to support the WaveTable functionality on cards such as | |
18 | SB Live! then you need to enable "Sequencer support" | |
19 | (CONFIG_SND_SEQUENCER). | |
20 | ||
21 | To make ALSA debug messages more verbose, enable the "Verbose printk" | |
22 | and "Debug" options. To check for memory leaks, turn on "Debug memory" | |
23 | too. "Debug detection" will add checks for the detection of cards. | |
24 | ||
25 | Please note that all the ALSA ISA drivers support the Linux isapnp API | |
26 | (if the card supports ISA PnP). You don't need to configure the cards | |
27 | using isapnptools. | |
28 | ||
29 | ||
30 | Creating ALSA devices | |
31 | ===================== | |
32 | ||
33 | This depends on your distribution, but normally you use the /dev/MAKEDEV | |
34 | script to create the necessary device nodes. On some systems you use a | |
35 | script named 'snddevices'. | |
36 | ||
37 | ||
38 | Module parameters | |
39 | ================= | |
40 | ||
41 | The user can load modules with options. If the module supports more than | |
42 | one card and you have more than one card of the same type then you can | |
43 | specify multiple values for the option separated by commas. | |
44 | ||
45 | Prior to version 0.9.0rc4 options had a 'snd_' prefix. This was removed. | |
46 | ||
47 | Module snd | |
48 | ---------- | |
49 | ||
50 | The core ALSA module. It is used by all ALSA card drivers. | |
51 | It takes the following options which have global effects. | |
52 | ||
53 | major - major number for sound driver | |
54 | - Default: 116 | |
55 | cards_limit | |
56 | - limiting card index for auto-loading (1-8) | |
57 | - Default: 1 | |
58 | - For auto-loading more than one card, specify this | |
59 | option together with snd-card-X aliases. | |
304cd07f TI |
60 | slots - Reserve the slot index for the given driver. |
61 | This option takes multiple strings. | |
62 | See "Module Autoloading Support" section for details. | |
1da177e4 LT |
63 | |
64 | Module snd-pcm-oss | |
65 | ------------------ | |
66 | ||
67 | The PCM OSS emulation module. | |
68 | This module takes options which change the mapping of devices. | |
69 | ||
70 | dsp_map - PCM device number maps assigned to the 1st OSS device. | |
71 | - Default: 0 | |
72 | adsp_map - PCM device number maps assigned to the 2st OSS device. | |
73 | - Default: 1 | |
74 | nonblock_open | |
6243008b | 75 | - Don't block opening busy PCM devices. Default: 1 |
1da177e4 LT |
76 | |
77 | For example, when dsp_map=2, /dev/dsp will be mapped to PCM #2 of | |
78 | the card #0. Similarly, when adsp_map=0, /dev/adsp will be mapped | |
79 | to PCM #0 of the card #0. | |
80 | For changing the second or later card, specify the option with | |
81 | commas, such like "dsp_map=0,1". | |
82 | ||
83 | nonblock_open option is used to change the behavior of the PCM | |
84 | regarding opening the device. When this option is non-zero, | |
85 | opening a busy OSS PCM device won't be blocked but return | |
86 | immediately with EAGAIN (just like O_NONBLOCK flag). | |
87 | ||
88 | Module snd-rawmidi | |
89 | ------------------ | |
90 | ||
91 | This module takes options which change the mapping of devices. | |
92 | similar to those of the snd-pcm-oss module. | |
93 | ||
94 | midi_map - MIDI device number maps assigned to the 1st OSS device. | |
95 | - Default: 0 | |
96 | amidi_map - MIDI device number maps assigned to the 2st OSS device. | |
97 | - Default: 1 | |
98 | ||
99 | Common parameters for top sound card modules | |
100 | -------------------------------------------- | |
101 | ||
102 | Each of top level sound card module takes the following options. | |
103 | ||
104 | index - index (slot #) of sound card | |
0ef797c5 | 105 | - Values: 0 through 31 or negative |
1da177e4 LT |
106 | - If nonnegative, assign that index number |
107 | - if negative, interpret as a bitmask of permissible | |
108 | indices; the first free permitted index is assigned | |
109 | - Default: -1 | |
110 | id - card ID (identifier or name) | |
111 | - Can be up to 15 characters long | |
112 | - Default: the card type | |
113 | - A directory by this name is created under /proc/asound/ | |
114 | containing information about the card | |
115 | - This ID can be used instead of the index number in | |
116 | identifying the card | |
117 | enable - enable card | |
118 | - Default: enabled, for PCI and ISA PnP cards | |
119 | ||

120 | Module snd-adlib |
121 | ---------------- | |
122 | ||
123 | Module for AdLib FM cards. | |
124 | ||
125 | port - port # for OPL chip | |
126 | ||
127 | This module supports multiple cards. It does not support autoprobe, so | |
128 | the port must be specified. For actual AdLib FM cards it will be 0x388. | |
129 | Note that this card does not have PCM support and no mixer; only FM | |
130 | synthesis. | |
131 | ||
132 | Make sure you have "sbiload" from the alsa-tools package available and, | |
133 | after loading the module, find out the assigned ALSA sequencer port | |
134 | number through "sbiload -l". Example output: | |
135 | ||
136 | Port Client name Port name | |
137 | 64:0 OPL2 FM synth OPL2 FM Port | |
138 | ||
139 | Load the std.sb and drums.sb patches also supplied by sbiload: | |
140 | ||
141 | sbiload -p 64:0 std.sb drums.sb | |
142 | ||
143 | If you use this driver to drive an OPL3, you can use std.o3 and drums.o3 | |
144 | instead. To have the card produce sound, use aplaymidi from alsa-utils: | |
145 | ||
146 | aplaymidi -p 64:0 foo.mid | |
147 | ||

1098 | The model name "genric" is treated as a special case. When this |
1099 | model is given, the driver uses the generic codec parser without | |
1100 | "codec-patch". It's sometimes good for testing and debugging. | |

1110 | Note 2: If you get click noises on output, try the module option |
1111 | position_fix=1 or 2. position_fix=1 will use the SD_LPIB | |
1112 | register value without FIFO size correction as the current | |
1113 | DMA pointer. position_fix=2 will make the driver to use | |
1114 | the position buffer instead of reading SD_LPIB register. | |
90f31e38 | 1115 | (Usually SD_LPIB register is more accurate than the |
c74db86b TI |
1116 | position buffer.) |

1118 | NB: If you get many "azx_get_response timeout" messages at |
1119 | loading, it's likely a problem of interrupts (e.g. ACPI irq | |
1120 | routing). Try to boot with options like "pci=noacpi". Also, you | |
1121 | can try "single_cmd=1" module option. This will switch the | |
1122 | communication method between HDA controller and codecs to the | |
1123 | single immediate commands instead of CORB/RIRB. Basically, the | |
1124 | single command mode is provided only for BIOS, and you won't get | |
1125 | unsolicited events, too. But, at least, this works independently | |
1126 | from the irq. Remember this is a last resort, and should be | |
1127 | avoided as much as possible... | |
1128 | ||
95904743 TI |
1129 | MORE NOTES ON "azx_get_response timeout" PROBLEMS: |
1130 | On some hardwares, you may need to add a proper probe_mask option | |
1131 | to avoid the "azx_get_response timeout" problem above, instead. | |
1132 | This occurs when the access to non-existing or non-working codec slot | |
1133 | (likely a modem one) causes a stall of the communication via HD-audio | |
1134 | bus. You can see which codec slots are probed by enabling | |
62cf872a | 1135 | CONFIG_SND_DEBUG_VERBOSE, or simply from the file name of the codec |
95904743 TI |
1136 | proc files. Then limit the slots to probe by probe_mask option. |
1137 | For example, probe_mask=1 means to probe only the first slot, and | |
1138 | probe_mask=4 means only the third slot. | |

1da177e4 | 1533 | |
8a3fb4d0 | 1534 | This module supports one chip and autoprobe. |
1da177e4 LT |
1535 | |
1536 | The power-management is supported. | |
1537 | ||
1538 | Note: on some notebooks the buffer address cannot be detected | |
1539 | automatically, or causes hang-up during initialization. | |
fff9289b ML |
1540 | In such a case, specify the buffer top address explicitly via |
1541 | the buffer_top option. | |
1da177e4 LT |
1542 | For example, |
1543 | Sony F250: buffer_top=0x25a800 | |
1544 | Sony F270: buffer_top=0x272800 | |
1545 | The driver supports only ac97 codec. It's possible to force | |
1546 | to initialize/use ac97 although it's not detected. In such a | |
1547 | case, use force_ac97=1 option - but *NO* guarantee whether it | |
1548 | works! | |
1549 | ||
1550 | Note: The NM256 chip can be linked internally with non-AC97 | |
1551 | codecs. This driver supports only the AC97 codec, and won't work | |
1552 | with machines with other (most likely CS423x or OPL3SAx) chips, | |
1553 | even though the device is detected in lspci. In such a case, try | |
1554 | other drivers, e.g. snd-cs4232 or snd-opl3sa2. Some has ISA-PnP | |
6243008b | 1555 | but some doesn't have ISA PnP. You'll need to specify isapnp=0 |
1da177e4 LT |
1556 | and proper hardware parameters in the case without ISA PnP. |
1557 | ||
1558 | Note: some laptops need a workaround for AC97 RESET. For the | |
1559 | known hardware like Dell Latitude LS and Sony PCG-F305, this | |
1560 | workaround is enabled automatically. For other laptops with a | |
1561 | hard freeze, you can try reset_workaround=1 option. | |

d1f38cf9 TI |
1563 | Note: Dell Latitude CSx laptops have another problem regarding |
1564 | AC97 RESET. On these laptops, reset_workaround2 option is | |
1565 | turned on as default. This option is worth to try if the | |
1566 | previous reset_workaround option doesn't help. | |
1567 | ||

1568 | Note: This driver is really crappy. It's a porting from the |
1569 | OSS driver, which is a result of black-magic reverse engineering. | |
1570 | The detection of codec will fail if the driver is loaded *after* | |
1571 | X-server as described above. You might be able to force to load | |
1572 | the module, but it may result in hang-up. Hence, make sure that | |
1573 | you load this module *before* X if you encounter this kind of | |
1574 | problem. | |

1905 | The below are options for wavefront_synth features: |
1906 | wf_raw - Assume that we need to boot the OS (default:no) | |
1907 | If yes, then during driver loading, the state of the board is | |
1908 | ignored, and we reset the board and load the firmware anyway. | |
1909 | fx_raw - Assume that the FX process needs help (default:yes) | |
1910 | If false, we'll leave the FX processor in whatever state it is | |
1911 | when the driver is loaded. The default is to download the | |
1912 | microprogram and associated coefficients to set it up for | |
1913 | "default" operation, whatever that means. | |
1914 | debug_default - Debug parameters for card initialization | |
1915 | wait_usecs - How long to wait without sleeping, usecs | |
1916 | (default:150) | |
1917 | This magic number seems to give pretty optimal throughput | |
1918 | based on my limited experimentation. | |
1919 | If you want to play around with it and find a better value, be | |
1920 | my guest. Remember, the idea is to get a number that causes us | |
1921 | to just busy wait for as many WaveFront commands as possible, | |
1922 | without coming up with a number so large that we hog the whole | |
1923 | CPU. | |
1924 | Specifically, with this number, out of about 134,000 status | |
1925 | waits, only about 250 result in a sleep. | |
1926 | sleep_interval - How long to sleep when waiting for reply | |
1927 | (default: 100) | |
1928 | sleep_tries - How many times to try sleeping during a wait | |
1929 | (default: 50) | |
1930 | ospath - Pathname to processed ICS2115 OS firmware | |
1931 | (default:wavefront.os) | |
1932 | The path name of the ISC2115 OS firmware. In the recent | |
1933 | version, it's handled via firmware loader framework, so it | |
1934 | must be installed in the proper path, typically, | |
1935 | /lib/firmware. | |
1936 | reset_time - How long to wait for a reset to take effect | |
1937 | (default:2) | |
1938 | ramcheck_time - How many seconds to wait for the RAM test | |
1939 | (default:20) | |
1940 | osrun_time - How many seconds to wait for the ICS2115 OS | |
1941 | (default:10) | |

b7fe4622 | 2071 | This module supports one chip and autoprobe. |
1da177e4 LT |
2072 | |
2073 | Note: on some SMP motherboards like MSI 694D the interrupts might | |
2074 | not be generated properly. In such a case, please try to | |
2075 | set the SMP (or MPS) version on BIOS to 1.1 instead of | |
2076 | default value 1.4. Then the interrupt number will be | |
2077 | assigned under 15. You might also upgrade your BIOS. | |
2078 | ||
2d7eb7cb | 2079 | Note: VIA8233/5/7 (not VIA8233A) can support DXS (direct sound) |
1da177e4 | 2080 | channels as the first PCM. On these channels, up to 4 |
2d7eb7cb SV |
2081 | streams can be played at the same time, and the controller |
2082 | can perform sample rate conversion with separate rates for | |
2083 | each channel. | |
1da177e4 LT |
2084 | As default (dxs_support = 0), 48k fixed rate is chosen |
2085 | except for the known devices since the output is often | |
2086 | noisy except for 48k on some mother boards due to the | |
2087 | bug of BIOS. | |
2d7eb7cb | 2088 | Please try once dxs_support=5 and if it works on other |
1da177e4 LT |
2089 | sample rates (e.g. 44.1kHz of mp3 playback), please let us |
2090 | know the PCI subsystem vendor/device id's (output of | |
2091 | "lspci -nv"). | |
cdc27f3a TI |
2092 | If dxs_support=5 does not work, try dxs_support=4; if it |
2093 | doesn't work too, try dxs_support=1. (dxs_support=1 is | |
6243008b | 2094 | usually for old motherboards. The correct implemented |
cdc27f3a | 2095 | board should work with 4 or 5.) If it still doesn't |
1da177e4 LT |
2096 | work and the default setting is ok, dxs_support=3 is the |
2097 | right choice. If the default setting doesn't work at all, | |
2098 | try dxs_support=2 to disable the DXS channels. | |
2099 | In any cases, please let us know the result and the | |
6243008b TI |
2100 | subsystem vendor/device ids. See "Links and Addresses" |
2101 | below. | |
1da177e4 LT |
2102 | |
2103 | Note: for the MPU401 on VIA823x, use snd-mpu401 driver | |

2142 | ---------------- | |
2143 | ||
2144 | Module for Digigram VX-Pocket VX222, V222 v2 and Mic cards. | |
2145 | ||
2146 | mic - Enable Microphone on V222 Mic (NYI) | |
2147 | ibl - Capture IBL size. (default = 0, minimum size) | |
2148 | ||
0ef797c5 | 2149 | This module supports multiple cards. |
1da177e4 LT |
2150 | |
2151 | When the driver is compiled as a module and the hotplug firmware | |
2152 | is supported, the firmware data is loaded via hotplug automatically. | |
2153 | Install the necessary firmware files in alsa-firmware package. | |
2154 | When no hotplug fw loader is available, you need to load the | |
2155 | firmware via vxloader utility in alsa-tools package. To invoke | |
2156 | vxloader automatically, add the following to /etc/modprobe.conf | |
2157 | ||
2158 | install snd-vx222 /sbin/modprobe --first-time -i snd-vx222 && /usr/bin/vxloader | |
2159 | ||
2160 | (for 2.2/2.4 kernels, add "post-install /usr/bin/vxloader" to | |
2161 | /etc/modules.conf, instead.) | |
2162 | IBL size defines the interrupts period for PCM. The smaller size | |
2163 | gives smaller latency but leads to more CPU consumption, too. | |
2164 | The size is usually aligned to 126. As default (=0), the smallest | |
2165 | size is chosen. The possible IBL values can be found in | |
2166 | /proc/asound/cardX/vx-status proc file. | |

2175 | ibl - Capture IBL size. (default = 0, minimum size) | |
2176 | ||
0ef797c5 | 2177 | This module supports multiple cards. The module is compiled only when |
1da177e4 LT |
2178 | PCMCIA is supported on kernel. |
2179 | ||
6243008b TI |
2180 | With the older 2.6.x kernel, to activate the driver via the card |
2181 | manager, you'll need to set up /etc/pcmcia/vxpocket.conf. See the | |
2182 | sound/pcmcia/vx/vxpocket.c. 2.6.13 or later kernel requires no | |
2183 | longer require a config file. | |
1da177e4 LT |
2184 | |
2185 | When the driver is compiled as a module and the hotplug firmware | |
2186 | is supported, the firmware data is loaded via hotplug automatically. | |
2187 | Install the necessary firmware files in alsa-firmware package. | |
2188 | When no hotplug fw loader is available, you need to load the | |
2189 | firmware via vxloader utility in alsa-tools package. | |

2223 | AC97 Quirk Option |
2224 | ================= | |
2225 | ||
2226 | The ac97_quirk option is used to enable/override the workaround for | |
2227 | specific devices on drivers for on-board AC'97 controllers like | |
2228 | snd-intel8x0. Some hardware have swapped output pins between Master | |
2229 | and Headphone, or Surround (thanks to confusion of AC'97 | |
2230 | specifications from version to version :-) | |
2231 | ||
2232 | The driver provides the auto-detection of known problematic devices, | |
2233 | but some might be unknown or wrongly detected. In such a case, pass | |
2234 | the proper value with this option. | |
2235 | ||
2236 | The following strings are accepted: | |
2237 | - default Don't override the default setting | |
10e4097f | 2238 | - none Disable the quirk |
6243008b TI |
2239 | - hp_only Bind Master and Headphone controls as a single control |
2240 | - swap_hp Swap headphone and master controls | |
2241 | - swap_surround Swap master and surround controls | |
2242 | - ad_sharing For AD1985, turn on OMS bit and use headphone | |
2243 | - alc_jack For ALC65x, turn on the jack sense mode | |
2244 | - inv_eapd Inverted EAPD implementation | |
2245 | - mute_led Bind EAPD bit for turning on/off mute LED | |
2246 | ||
2247 | For backward compatibility, the corresponding integer value -1, 0, | |
2248 | ... are accepted, too. | |
2249 | ||
2250 | For example, if "Master" volume control has no effect on your device | |
2251 | but only "Headphone" does, pass ac97_quirk=hp_only module option. | |
2252 | ||
2253 | ||
1da177e4 LT |
2254 | Configuring Non-ISAPNP Cards |
2255 | ============================ | |
2256 | ||
2257 | When the kernel is configured with ISA-PnP support, the modules | |
2258 | supporting the isapnp cards will have module options "isapnp". | |
2259 | If this option is set, *only* the ISA-PnP devices will be probed. | |
2260 | For probing the non ISA-PnP cards, you have to pass "isapnp=0" option | |
2261 | together with the proper i/o and irq configuration. | |
2262 | ||
2263 | When the kernel is configured without ISA-PnP support, isapnp option | |
2264 | will be not built in. | |
2265 | ||
2266 | ||
2267 | Module Autoloading Support | |
2268 | ========================== | |
2269 | ||
2270 | The ALSA drivers can be loaded automatically on demand by defining | |
2271 | module aliases. The string 'snd-card-%1' is requested for ALSA native | |
2272 | devices where %i is sound card number from zero to seven. | |
2273 | ||
2274 | To auto-load an ALSA driver for OSS services, define the string | |
2275 | 'sound-slot-%i' where %i means the slot number for OSS, which | |
2276 | corresponds to the card index of ALSA. Usually, define this | |
d533f671 | 2277 | as the same card module. |
1da177e4 LT |
2278 | |
2279 | An example configuration for a single emu10k1 card is like below: | |
2280 | ----- /etc/modprobe.conf | |
2281 | alias snd-card-0 snd-emu10k1 | |
2282 | alias sound-slot-0 snd-emu10k1 | |
2283 | ----- /etc/modprobe.conf | |
2284 | ||
2285 | The available number of auto-loaded sound cards depends on the module | |
2286 | option "cards_limit" of snd module. As default it's set to 1. | |
2287 | To enable the auto-loading of multiple cards, specify the number of | |
2288 | sound cards in that option. | |
2289 | ||
2290 | When multiple cards are available, it'd better to specify the index | |
2291 | number for each card via module option, too, so that the order of | |
2292 | cards is kept consistent. | |
2293 | ||
2294 | An example configuration for two sound cards is like below: | |
2295 | ||
2296 | ----- /etc/modprobe.conf | |
2297 | # ALSA portion | |
2298 | options snd cards_limit=2 | |
2299 | alias snd-card-0 snd-interwave | |
2300 | alias snd-card-1 snd-ens1371 | |
2301 | options snd-interwave index=0 | |
2302 | options snd-ens1371 index=1 | |
2303 | # OSS/Free portion | |
2304 | alias sound-slot-0 snd-interwave | |
2305 | alias sound-slot-1 snd-ens1371 | |
2fe0ae78 | 2306 | ----- /etc/modprobe.conf |
1da177e4 LT |
2307 | |
2308 | In this example, the interwave card is always loaded as the first card | |
2309 | (index 0) and ens1371 as the second (index 1). | |
2310 | ||
304cd07f TI |
2311 | Alternative (and new) way to fixate the slot assignment is to use |
2312 | "slots" option of snd module. In the case above, specify like the | |
2313 | following: | |
2314 | ||
2315 | options snd slots=snd-interwave,snd-ens1371 | |
2316 | ||
2317 | Then, the first slot (#0) is reserved for snd-interwave driver, and | |
2318 | the second (#1) for snd-ens1371. You can omit index option in each | |
2319 | driver if slots option is used (although you can still have them at | |
2320 | the same time as long as they don't conflict). | |
2321 | ||
2322 | The slots option is especially useful for avoiding the possible | |
2323 | hot-plugging and the resultant slot conflict. For example, in the | |
2324 | case above again, the first two slots are already reserved. If any | |
2325 | other driver (e.g. snd-usb-audio) is loaded before snd-interwave or | |
2326 | snd-ens1371, it will be assigned to the third or later slot. | |

2328 | When a module name is given with '!', the slot will be given for any |
2329 | modules but that name. For example, "slots=!snd-pcsp" will reserve | |
2330 | the first slot for any modules but snd-pcsp. | |

2333 | ALSA PCM devices to OSS devices mapping | |
2334 | ======================================= | |
2335 | ||
2336 | /dev/snd/pcmC0D0[c|p] -> /dev/audio0 (/dev/audio) -> minor 4 | |
2337 | /dev/snd/pcmC0D0[c|p] -> /dev/dsp0 (/dev/dsp) -> minor 3 | |
2338 | /dev/snd/pcmC0D1[c|p] -> /dev/adsp0 (/dev/adsp) -> minor 12 | |
2339 | /dev/snd/pcmC1D0[c|p] -> /dev/audio1 -> minor 4+16 = 20 | |
2340 | /dev/snd/pcmC1D0[c|p] -> /dev/dsp1 -> minor 3+16 = 19 | |
2341 | /dev/snd/pcmC1D1[c|p] -> /dev/adsp1 -> minor 12+16 = 28 | |
2342 | /dev/snd/pcmC2D0[c|p] -> /dev/audio2 -> minor 4+32 = 36 | |
2343 | /dev/snd/pcmC2D0[c|p] -> /dev/dsp2 -> minor 3+32 = 39 | |
2344 | /dev/snd/pcmC2D1[c|p] -> /dev/adsp2 -> minor 12+32 = 44 | |
2345 | ||
2346 | The first number from /dev/snd/pcmC{X}D{Y}[c|p] expression means | |
2347 | sound card number and second means device number. The ALSA devices | |
2348 | have either 'c' or 'p' suffix indicating the direction, capture and | |
2349 | playback, respectively. | |
2350 | ||
2351 | Please note that the device mapping above may be varied via the module | |
2352 | options of snd-pcm-oss module. | |

2355 | Proc interfaces (/proc/asound) |
2356 | ============================== | |
2357 | ||
2358 | /proc/asound/card#/pcm#[cp]/oss | |
2359 | ------------------------------- | |
2360 | String "erase" - erase all additional informations about OSS applications | |
2361 | String "<app_name> <fragments> <fragment_size> [<options>]" | |
2362 | ||
2363 | <app_name> - name of application with (higher priority) or without path | |
2364 | <fragments> - number of fragments or zero if auto | |
2365 | <fragment_size> - size of fragment in bytes or zero if auto | |
2366 | <options> - optional parameters | |
2367 | - disable the application tries to open a pcm device for | |
2368 | this channel but does not want to use it. | |
2369 | (Cause a bug or mmap needs) | |
2370 | It's good for Quake etc... | |
2371 | - direct don't use plugins | |
2372 | - block force block mode (rvplayer) | |
2373 | - non-block force non-block mode | |
2374 | - whole-frag write only whole fragments (optimization affecting | |
2375 | playback only) | |
2376 | - no-silence do not fill silence ahead to avoid clicks | |
10f69f9e TI |
2377 | - buggy-ptr Returns the whitespace blocks in GETOPTR ioctl |
2378 | instead of filled blocks | |

2381 | echo "squake 0 0 disable" > /proc/asound/card0/pcm0c/oss | |
2382 | echo "rvplayer 0 0 block" > /proc/asound/card0/pcm0p/oss | |

2385 | Early Buffer Allocation |
2386 | ======================= | |
2387 | ||
2388 | Some drivers (e.g. hdsp) require the large contiguous buffers, and | |
2389 | sometimes it's too late to find such spaces when the driver module is | |
2390 | actually loaded due to memory fragmentation. You can pre-allocate the | |
2391 | PCM buffers by loading snd-page-alloc module and write commands to its | |
2392 | proc file in prior, for example, in the early boot stage like | |
2393 | /etc/init.d/*.local scripts. | |
2394 | ||
2395 | Reading the proc file /proc/drivers/snd-page-alloc shows the current | |
2396 | usage of page allocation. In writing, you can send the following | |
2397 | commands to the snd-page-alloc driver: | |
2398 | ||
2399 | - add VENDOR DEVICE MASK SIZE BUFFERS | |
2400 | ||
2401 | VENDOR and DEVICE are PCI vendor and device IDs. They take | |
2402 | integer numbers (0x prefix is needed for the hex). | |
2403 | MASK is the PCI DMA mask. Pass 0 if not restricted. | |
2404 | SIZE is the size of each buffer to allocate. You can pass | |
2405 | k and m suffix for KB and MB. The max number is 16MB. | |
2406 | BUFFERS is the number of buffers to allocate. It must be greater | |
2407 | than 0. The max number is 4. | |
2408 | ||
2409 | - erase | |
2410 | ||
2411 | This will erase the all pre-allocated buffers which are not in | |
2412 | use. | |
