A larger buffer (e.g. 2048) is preferred 25 for systems using PulseAudio. The default 64 is chosen just 26 for compatibility reasons. 27 28 Note that the pre-allocation size can be changed dynamically 29 via a proc file (/proc/asound/card*/pcm*/sub*/prealloc), too. 30 31config SND_HDA_HWDEP 32 bool "Build hwdep interface for HD-audio driver" 33 select SND_HWDEP 34 help 35 Say Y here to build a hwdep interface for HD-audio driver. 36 This interface can be used for out-of-band communication 37 with codecs for debugging purposes. 38 39config SND_HDA_RECONFIG 40 bool "Allow dynamic codec reconfiguration (EXPERIMENTAL)" 41 depends on SND_HDA_HWDEP && EXPERIMENTAL 42 help 43 Say Y here to enable the HD-audio codec re-configuration feature. 44 This adds the sysfs interfaces to allow user to clear the whole 45 codec configuration, change the codec setup, add extra verbs, 46 and re-configure the codec dynamically. 47 48config SND_HDA_INPUT_BEEP 49 bool "Support digital beep via input layer" 50 depends on INPUT=y || INPUT=SND_HDA_INTEL 51 help 52 Say Y here to build a digital beep interface for HD-audio 53 driver.
