Say Y or M to enable MIDI sequencer and router support. This
|
|
feature allows routing and enqueueing of MIDI events. Events
|
|
can be processed at a given time.
|
|
|
|
Many programs require this feature, so you should enable it
|
|
unless you know what you're doing.

config SND_SEQ_DUMMY

tristate "Sequencer dummy client"
|
|
depends on SND_SEQUENCER
|
|
help
|
|
Say Y here to enable the dummy sequencer client. This client
|
|
is a simple MIDI-through client: all normal input events are
|
|
redirected to the output port immediately.
|
|
|
|
You don't need this unless you want to connect many MIDI
|
|
devices or applications together.
|
|
|
|
To compile this driver as a module, choose M here: the module
|
|
will be called snd-seq-dummy.

To enable OSS mixer API emulation (/dev/mixer*), say Y here

and read <file:Documentation/sound/alsa/OSS-Emulation.txt>.
|

Many programs still use the OSS API, so say Y.

To enable OSS digital audio (PCM) emulation (/dev/dsp*), say Y

here and read <file:Documentation/sound/alsa/OSS-Emulation.txt>.

|
|
help
|
|
If you disable this option, the ALSA's OSS PCM API will not
|
|
support conversion of channels, formats and rates. It will
|
|
behave like most of new OSS/Free drivers in 2.4/2.6 kernels.

help
|
|
Say Y here to enable OSS sequencer emulation (both
|
|
/dev/sequencer and /dev/music interfaces).
|
|
|
|
Many programs still use the OSS API, so say Y.
|
|
|
|
If you choose M in "Sequencer support" (SND_SEQUENCER),
|
|
this will be compiled as a module. The module will be called
|
|
snd-seq-oss.

config SND_RTCTIMER

|
tristate "RTC Timer support"
|
|
depends on SND && RTC
|
|
select SND_TIMER
|
|
help
|
|
Say Y here to enable RTC timer support for ALSA. ALSA uses
|
|
the RTC timer as a precise timing source and maps the RTC
|
|
timer to ALSA's timer interface. The ALSA sequencer code also
|
|
can use this timing source.
|
|
|
|
To compile this driver as a module, choose M here: the module
|
|
will be called snd-rtctimer.
|
|
|
|
config SND_SEQ_RTCTIMER_DEFAULT
|
|
bool "Use RTC as default sequencer timer"
|

depends on SND_RTCTIMER && SND_SEQUENCER
|
|
default y
|
|
help
|
|
Say Y here to use the RTC timer as the default sequencer
|
|
timer. This is strongly recommended because it ensures
|
|
precise MIDI timing even when the system timer runs at less
|
|
than 1000 Hz.
|
|
|
|
If in doubt, say Y.
|
|
|
|
config SND_DYNAMIC_MINORS
|
|
bool "Dynamic device file minor numbers (EXPERIMENTAL)"
|
|
depends on SND && EXPERIMENTAL
|
|
help
|
|
If you say Y here, the minor numbers of ALSA device files in
|
|
/dev/snd/ are allocated dynamically. This allows you to have
|
|
more than 8 sound cards, but requires a dynamic device file
|
|
system like udev.
|
|
|
|
If you are unsure about this, say N here.
|

config SND_SUPPORT_OLD_API

or older).

default y
|
|
help
|
|
Say Y here to include code for verbose procfs contents (provides
|
|
usefull information to developers when a problem occurs). On the
|
|
other side, it makes the ALSA subsystem larger.
|
|
|
|
config SND_VERBOSE_PRINTK

|
|
help
|
|
Say Y here to enable verbose log messages. These messages
|
|
will help to identify source file and position containing
|
|
printed messages.
|
|
|
|
You don't need this unless you're debugging ALSA.
|

detecting devices.
