|
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.
|
|
On x86 systems, the default is zero as we need no preallocation.
|
|
|
|
Note that the pre-allocation size can be changed dynamically
|
|
via a proc file (/proc/asound/card*/pcm*/sub*/prealloc), too.
