help
If you don't have a sound card in your computer, you can include a
driver for the PC speaker which allows it to act like a primitive
sound card.
This driver also replaces the pcspkr driver for beeps.
You can compile this as a module which will be called snd-pcsp.
WARNING: if you already have a soundcard, enabling this
driver may lead to a problem. Namely, it may get loaded
before the other sound driver of yours, making the
pc-speaker a default sound device. Which is likely not
what you want. To make this driver play nicely with other
sound driver, you can add this into your /etc/modprobe.conf:
options snd-pcsp index=2
You don't need this driver if you only want your pc-speaker to beep.
You don't need this driver if you have a tablet piezo beeper
in your PC instead of the real speaker.
Say N if you have a sound card.
Say M if you don't.
Say Y only if you really know what you do.
config SND_DUMMY
tristate "Dummy (/dev/null) soundcard"
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.

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.

help
The ESI Miditerminal 4140 is a 4 In 4 Out MIDI Interface with
additional SMPTE Timecode capabilities for the parallel port.
Say 'Y' to include support for this device.
To compile this driver as a module, chose 'M' here: the module
will be called snd-mts64.
config SND_SERIAL_U16550
tristate "UART16550 serial MIDI driver"
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.

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.
