36 tristate "Dummy (/dev/null) soundcard"
40 Say Y here to include the dummy driver. This driver does
41 nothing, but emulates various mixer controls and PCM devices.
43 You don't need this unless you're testing the hardware support
44 of programs using the ALSA API.
46 To compile this driver as a module, choose M here: the module
47 will be called snd-dummy.
50 tristate "Virtual MIDI soundcard"
51 depends on SND_SEQUENCER
55 Say Y here to include the virtual MIDI driver. This driver
56 allows to connect applications using raw MIDI devices to
59 If you don't know what MIDI is, say N here.
61 To compile this driver as a module, choose M here: the module
62 will be called snd-virmidi.
65 tristate "MOTU MidiTimePiece AV multiport MIDI"
69 To use a MOTU MidiTimePiece AV multiport MIDI adapter
70 connected to the parallel port, say Y here and make sure that
71 the standard parallel port driver isn't used for the port.
73 To compile this driver as a module, choose M here: the module
74 will be called snd-mtpav.
76 config SND_SERIAL_U16550
77 tristate "UART16550 serial MIDI driver"
81 To include support for MIDI serial port interfaces, say Y here
82 and read <file:Documentation/sound/alsa/serial-u16550.txt>.
83 This driver works with serial UARTs 16550 and better.
85 This driver accesses the serial port hardware directly, so
86 make sure that the standard serial driver isn't used or
87 deactivated with setserial before loading this driver.
89 To compile this driver as a module, choose M here: the module
90 will be called snd-serial-u16550.
93 tristate "Generic MPU-401 UART driver"
95 select SND_MPU401_UART
97 Say Y here to include support for MIDI ports compatible with
98 the Roland MPU-401 interface in UART mode.
100 To compile this driver as a module, choose M here: the module
101 will be called snd-mpu401.
103 config SND_AC97_POWER_SAVE
104 bool "AC97 Power-Saving Mode"
105 depends on SND_AC97_CODEC && EXPERIMENTAL
108 Say Y here to enable the aggressive power-saving support of
109 AC97 codecs. In this mode, the power-mode is dynamically
110 controlled at each open/close.
112 The mode is activated by passing power_save=1 option to
113 snd-ac97-codec driver. You can toggle it dynamically over
