| 24 | help |
| 25 | Specifies the default pre-allocated buffer-size in kB for the |
| 26 | HD-audio driver. A larger buffer (e.g. 2048) is preferred |
| 27 | for systems using PulseAudio. The default 64 is chosen just |
| 28 | for compatibility reasons. |
| 29 | |
| 30 | Note that the pre-allocation size can be changed dynamically |
| 31 | via a proc file (/proc/asound/card*/pcm*/sub*/prealloc), too. |
