| 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 2048 as a reasonable value for |
| most of modern systems. |
| |
| Note that the pre-allocation size can be changed dynamically |
| via a proc file (/proc/asound/card*/pcm*/sub*/prealloc), too. |
