| 28 | Specifies the default pre-allocated buffer-size in kB for the |
| 29 | HD-audio driver. A larger buffer (e.g. 2048) is preferred |
| 30 | for systems using PulseAudio. The default 64 is chosen just |
| 31 | for compatibility reasons. |
| 32 | |
| 33 | Note that the pre-allocation size can be changed dynamically |
| 34 | via a proc file (/proc/asound/card*/pcm*/sub*/prealloc), too. |
