# ALSA soundcard-configuration config SND_TIMER tristate depends on SND config SND_PCM tristate select SND_TIMER depends on SND config SND_HWDEP tristate depends on SND config SND_RAWMIDI tristate depends on SND config SND_SEQUENCER tristate "Sequencer support" depends on SND select SND_TIMER help Say Y or M to enable MIDI sequencer and router support. This feature allows routing and enqueueing of MIDI events. Events can be processed at a given time. Many programs require this feature, so you should enable it unless you know what you're doing. config SND_SEQ_DUMMY tristate "Sequencer dummy client" depends on SND_SEQUENCER help Say Y here to enable the dummy sequencer client. This client is a simple MIDI-through client: all normal input events are redirected to the output port immediately. You don't need this unless you want to connect many MIDI devices or applications together. To compile this driver as a module, choose M here: the module will be called snd-seq-dummy. config SND_OSSEMUL bool depends on SND config SND_MIXER_OSS tristate "OSS Mixer API" depends on SND select SND_OSSEMUL help To enable OSS mixer API emulation (/dev/mixer*), say Y here and read . 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-mixer-oss. config SND_PCM_OSS tristate "OSS PCM (digital audio) API" depends on SND select SND_OSSEMUL select SND_PCM help To enable OSS digital audio (PCM) emulation (/dev/dsp*), say Y here and read . 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-pcm-oss. config SND_SEQUENCER_OSS bool "OSS Sequencer API" depends on SND && SND_SEQUENCER select SND_OSSEMUL help Say Y here to enable OSS sequencer emulation (both /dev/sequencer and /dev/music interfaces). 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. config SND_RTCTIMER tristate "RTC Timer support" depends on SND && RTC select SND_TIMER help Say Y here to enable RTC timer support for ALSA. ALSA uses the RTC timer as a precise timing source and maps the RTC timer to ALSA's timer interface. The ALSA sequencer code also can use this timing source. To compile this driver as a module, choose M here: the module will be called snd-rtctimer. config SND_VERBOSE_PRINTK bool "Verbose printk" depends on SND help Say Y here to enable verbose log messages. These messages will help to identify source file and position containing printed messages. You don't need this unless you're debugging ALSA. config SND_DEBUG bool "Debug" depends on SND help Say Y here to enable ALSA debug code. config SND_DEBUG_MEMORY bool "Debug memory" depends on SND_DEBUG help Say Y here to enable debugging of memory allocations. config SND_DEBUG_DETECT bool "Debug detection" depends on SND_DEBUG help Say Y here to enable extra-verbose log messages printed when detecting devices. config SND_GENERIC_PM bool depends on SND
