  22         select SND_TIMER
  23         help
  24           Say Y or M to enable MIDI sequencer and router support.  This
  25           feature allows routing and enqueueing of MIDI events.  Events
  26           can be processed at a given time.
  27
  28           Many programs require this feature, so you should enable it
  29           unless you know what you're doing.

  31 config SND_SEQ_DUMMY
  32         tristate "Sequencer dummy client"
  33         depends on SND_SEQUENCER
  34         help
  35           Say Y here to enable the dummy sequencer client.  This client
  36           is a simple MIDI-through client: all normal input events are
  37           redirected to the output port immediately.
  38
  39           You don't need this unless you want to connect many MIDI
  40           devices or applications together.

  42           To compile this driver as a module, choose M here: the module
  43           will be called snd-seq-dummy.

  54           To enable OSS mixer API emulation (/dev/mixer*), say Y here
  55           and read <file:Documentation/sound/alsa/OSS-Emulation.txt>.
  56
  57           Many programs still use the OSS API, so say Y.

  81           Say Y here to enable OSS sequencer emulation (both
  82           /dev/sequencer and /dev/music interfaces).

  92         select SND_TIMER
  93         help
  94           Say Y here to enable RTC timer support for ALSA.  ALSA uses
  95           the RTC timer as a precise timing source and maps the RTC
  96           timer to ALSA's timer interface.  The ALSA sequencer code also
  97           can use this timing source.
  98
  99           To compile this driver as a module, choose M here: the module
 100           will be called snd-rtctimer.

 106           Say Y here to enable verbose log messages.  These messages
 107           will help to identify source file and position containing
 108           printed messages.
 109
 110           You don't need this unless you're debugging ALSA.
