To compile this driver as a module, choose M here: the module
will be called snd-pcm-oss.
+config SND_PCM_OSS_PLUGINS
+ bool "OSS PCM (digital audio) API - Include plugin system"
+ depends on SND_PCM_OSS
+ default y
+ 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.

config SND_SEQUENCER_OSS
bool "OSS Sequencer API"
depends on SND && SND_SEQUENCER
Many programs still use the OSS API, so say Y.
- To compile this driver as a module, choose M here: the module
- will be called snd-seq-oss.
+ 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"
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"
+ depends on SND
+ 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
+ bool "Support old ALSA API"
+ depends on SND
+ default y
+ help
+ Say Y here to support the obsolete ALSA PCM API (ver.0.9.0 rc3
+ or older).
+
+config SND_VERBOSE_PROCFS
+ bool "Verbose procfs contents"
+ depends on SND && PROC_FS
+ 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.

Say Y here to enable ALSA debug code.

- Say Y here to enable debugging of memory allocations.

config SND_DEBUG_DETECT
bool "Debug detection"

Say Y here to enable extra-verbose log messages printed when
detecting devices.

+ Say Y to enable the PCM ring buffer overrun/underrun debugging.
+ It is usually not required, but if you have trouble with
+ sound clicking when system is loaded, it may help to determine
+ the process or driver which causes the scheduling gaps.
