16 tristate "Sequencer support"
20 Say Y or M to enable MIDI sequencer and router support. This
21 feature allows routing and enqueueing of MIDI events. Events
22 can be processed at a given time.
24 Many programs require this feature, so you should enable it
25 unless you know what you're doing.
28 tristate "Sequencer dummy client"
29 depends on SND_SEQUENCER
31 Say Y here to enable the dummy sequencer client. This client
32 is a simple MIDI-through client: all normal input events are
33 redirected to the output port immediately.
35 You don't need this unless you want to connect many MIDI
36 devices or applications together.
38 To compile this driver as a module, choose M here: the module
39 will be called snd-seq-dummy.
45 tristate "OSS Mixer API"
49 To enable OSS mixer API emulation (/dev/mixer*), say Y here
50 and read <file:Documentation/sound/alsa/OSS-Emulation.txt>.
52 Many programs still use the OSS API, so say Y.
54 To compile this driver as a module, choose M here: the module
55 will be called snd-mixer-oss.
58 tristate "OSS PCM (digital audio) API"
63 To enable OSS digital audio (PCM) emulation (/dev/dsp*), say Y
64 here and read <file:Documentation/sound/alsa/OSS-Emulation.txt>.
66 Many programs still use the OSS API, so say Y.
68 To compile this driver as a module, choose M here: the module
69 will be called snd-pcm-oss.
71 config SND_SEQUENCER_OSS
72 bool "OSS Sequencer API"
73 depends on SND_SEQUENCER
76 Say Y here to enable OSS sequencer emulation (both
77 /dev/sequencer and /dev/music interfaces).
79 Many programs still use the OSS API, so say Y.
81 To compile this driver as a module, choose M here: the module
82 will be called snd-seq-oss.
85 tristate "Emulation for 32-bit applications"
86 depends on SND && COMPAT
92 Say Y here to enable the emulation for 32-bit ALSA-native
95 To compile this driver as a module, choose M here: the module
96 will be called snd-ioctl32.
99 tristate "RTC Timer support"
100 depends on SND && RTC
103 Say Y here to enable RTC timer support for ALSA. ALSA uses
104 the RTC timer as a precise timing source and maps the RTC
105 timer to ALSA's timer interface. The ALSA sequencer code also
106 can use this timing source.
108 To compile this driver as a module, choose M here: the module
109 will be called snd-rtctimer.
111 config SND_VERBOSE_PRINTK
112 bool "Verbose printk"
115 Say Y here to enable verbose log messages. These messages
116 will help to identify source file and position containing
119 You don't need this unless you're debugging ALSA.
125 Say Y here to enable ALSA debug code.
127 config SND_DEBUG_MEMORY
131 Say Y here to enable debugging of memory allocations.
133 config SND_DEBUG_DETECT
134 bool "Debug detection"
137 Say Y here to enable extra-verbose log messages printed when
