20 tristate "Sequencer support"
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.
28 Many programs require this feature, so you should enable it
29 unless you know what you're doing.
32 tristate "Sequencer dummy client"
33 depends on SND_SEQUENCER
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.
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.
50 tristate "OSS Mixer API"
54 To enable OSS mixer API emulation (/dev/mixer*), say Y here
55 and read <file:Documentation/sound/alsa/OSS-Emulation.txt>.
57 Many programs still use the OSS API, so say Y.
59 To compile this driver as a module, choose M here: the module
60 will be called snd-mixer-oss.
63 tristate "OSS PCM (digital audio) API"
68 To enable OSS digital audio (PCM) emulation (/dev/dsp*), say Y
69 here and read <file:Documentation/sound/alsa/OSS-Emulation.txt>.
71 Many programs still use the OSS API, so say Y.
73 To compile this driver as a module, choose M here: the module
74 will be called snd-pcm-oss.
76 config SND_SEQUENCER_OSS
77 bool "OSS Sequencer API"
78 depends on SND && SND_SEQUENCER
81 Say Y here to enable OSS sequencer emulation (both
82 /dev/sequencer and /dev/music interfaces).
84 Many programs still use the OSS API, so say Y.
86 To compile this driver as a module, choose M here: the module
87 will be called snd-seq-oss.
90 tristate "RTC Timer support"
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.
99 To compile this driver as a module, choose M here: the module
100 will be called snd-rtctimer.
102 config SND_VERBOSE_PRINTK
103 bool "Verbose printk"
106 Say Y here to enable verbose log messages. These messages
107 will help to identify source file and position containing
110 You don't need this unless you're debugging ALSA.
116 Say Y here to enable ALSA debug code.
118 config SND_DEBUG_MEMORY
122 Say Y here to enable debugging of memory allocations.
124 config SND_DEBUG_DETECT
125 bool "Debug detection"
128 Say Y here to enable extra-verbose log messages printed when
131 config SND_GENERIC_PM
