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