29 Specifies the default pre-allocated buffer-size in kB for the
30 HD-audio driver. A larger buffer (e.g. 2048) is preferred
31 for systems using PulseAudio. The default 64 is chosen just
32 for compatibility reasons.
33 On x86 systems, the default is 2048 as a reasonable value for
34 most of modern systems.
36 Note that the pre-allocation size can be changed dynamically
37 via a proc file (/proc/asound/card*/pcm*/sub*/prealloc), too.
