config SND_DUMMY
tristate "Dummy (/dev/null) soundcard"
depends on SND
select SND_PCM
help
Say Y here to include the dummy driver. This driver does
nothing, but emulates various mixer controls and PCM devices.
You don't need this unless you're testing the hardware support
of programs using the ALSA API.
To compile this driver as a module, choose M here: the module
will be called snd-dummy.
config SND_VIRMIDI
tristate "Virtual MIDI soundcard"
depends on SND_SEQUENCER
select SND_TIMER
select SND_RAWMIDI
help
Say Y here to include the virtual MIDI driver. This driver
allows to connect applications using raw MIDI devices to
sequencer clients.
If you don't know what MIDI is, say N here.
To compile this driver as a module, choose M here: the module
will be called snd-virmidi.
config SND_MTPAV
tristate "MOTU MidiTimePiece AV multiport MIDI"
depends on SND
select SND_RAWMIDI
help
To use a MOTU MidiTimePiece AV multiport MIDI adapter
connected to the parallel port, say Y here and make sure that
the standard parallel port driver isn't used for the port.
To compile this driver as a module, choose M here: the module
will be called snd-mtpav.
config SND_SERIAL_U16550
tristate "UART16550 serial MIDI driver"
depends on SND
select SND_RAWMIDI
help
To include support for MIDI serial port interfaces, say Y here
and read <file:Documentation/sound/alsa/serial-u16550.txt>.
This driver works with serial UARTs 16550 and better.
This driver accesses the serial port hardware directly, so
make sure that the standard serial driver isn't used or
deactivated with setserial before loading this driver.
To compile this driver as a module, choose M here: the module
will be called snd-serial-u16550.
config SND_MPU401
tristate "Generic MPU-401 UART driver"
depends on SND
select SND_MPU401_UART
help
Say Y here to include support for MIDI ports compatible with
the Roland MPU-401 interface in UART mode.
To compile this driver as a module, choose M here: the module
will be called snd-mpu401.
config SND_AC97_POWER_SAVE
bool "AC97 Power-Saving Mode"
depends on SND_AC97_CODEC && EXPERIMENTAL
default n
help
Say Y here to enable the aggressive power-saving support of
AC97 codecs. In this mode, the power-mode is dynamically
controlled at each open/close.
The mode is activated by passing power_save=1 option to
snd-ac97-codec driver. You can toggle it dynamically over
sysfs, too.
