21 int "Pre-allocated buffer size for HD-audio driver"
25 Specifies the default pre-allocated buffer-size in kB for the
26 HD-audio driver. A larger buffer (e.g. 2048) is preferred
27 for systems using PulseAudio. The default 64 is chosen just
28 for compatibility reasons.
30 Note that the pre-allocation size can be changed dynamically
31 via a proc file (/proc/asound/card*/pcm*/sub*/prealloc), too.
