3 | * Driver CA0106 chips. e.g. Sound Blaster Audigy LS and Live 24bit | |
48510070 | 4 | * Version: 0.0.25 |
1da177e4 LT |
5 | * |
6 | * FEATURES currently supported: | |
7 | * Front, Rear and Center/LFE. | |
8 | * Surround40 and Surround51. | |
9 | * Capture from MIC an LINE IN input. | |
10 | * SPDIF digital playback of PCM stereo and AC3/DTS works. | |
11 | * (One can use a standard mono mini-jack to one RCA plugs cable. | |
12 | * or one can use a standard stereo mini-jack to two RCA plugs cable. | |
13 | * Plug one of the RCA plugs into the Coax input of the external decoder/receiver.) | |
14 | * ( In theory one could output 3 different AC3 streams at once, to 3 different SPDIF outputs. ) | |
15 | * Notes on how to capture sound: | |
16 | * The AC97 is used in the PLAYBACK direction. | |
17 | * The output from the AC97 chip, instead of reaching the speakers, is fed into the Philips 1361T ADC. | |
18 | * So, to record from the MIC, set the MIC Playback volume to max, | |
19 | * unmute the MIC and turn up the MASTER Playback volume. | |
20 | * So, to prevent feedback when capturing, minimise the "Capture feedback into Playback" volume. | |
21 | * | |
22 | * The only playback controls that currently do anything are: - | |
23 | * Analog Front | |
24 | * Analog Rear | |
25 | * Analog Center/LFE | |
26 | * SPDIF Front | |
27 | * SPDIF Rear | |
28 | * SPDIF Center/LFE | |
29 | * | |
30 | * For capture from Mic in or Line in. | |
31 | * Digital/Analog ( switch must be in Analog mode for CAPTURE. ) | |
32 | * | |
33 | * CAPTURE feedback into PLAYBACK | |
34 | * | |
35 | * Changelog: | |
36 | * Support interrupts per period. | |
37 | * Removed noise from Center/LFE channel when in Analog mode. | |
38 | * Rename and remove mixer controls. | |
39 | * 0.0.6 | |
40 | * Use separate card based DMA buffer for periods table list. | |
41 | * 0.0.7 | |
42 | * Change remove and rename ctrls into lists. | |
43 | * 0.0.8 | |
44 | * Try to fix capture sources. | |
45 | * 0.0.9 | |
46 | * Fix AC3 output. | |
47 | * Enable S32_LE format support. | |
48 | * 0.0.10 | |
49 | * Enable playback 48000 and 96000 rates. (Rates other that these do not work, even with "plug:front".) | |
50 | * 0.0.11 | |
51 | * Add Model name recognition. | |
52 | * 0.0.12 | |
53 | * Correct interrupt timing. interrupt at end of period, instead of in the middle of a playback period. | |
54 | * Remove redundent "voice" handling. | |
55 | * 0.0.13 | |
56 | * Single trigger call for multi channels. | |
57 | * 0.0.14 | |
58 | * Set limits based on what the sound card hardware can do. | |
59 | * playback periods_min=2, periods_max=8 | |
60 | * capture hw constraints require period_size = n * 64 bytes. | |
61 | * playback hw constraints require period_size = n * 64 bytes. | |
62 | * 0.0.15 | |
63 | * Minor updates. | |
64 | * 0.0.16 | |
65 | * Implement 192000 sample rate. | |
