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.

31config 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.

79 select SND_OSSEMUL
80 help
81 Say Y here to enable OSS sequencer emulation (both
82 /dev/sequencer and /dev/music interfaces).
83
84 Many programs still use the OSS API, so say Y.

89config SND_RTCTIMER
90 tristate "RTC Timer support"
91 depends on SND && RTC
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.

105 help
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.
