| 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. | |
| f4b4bdf2 | 33 | On x86 systems, the default is zero as we need no preallocation. |
| d39513f8 VK |
34 | |
| 35 | Note that the pre-allocation size can be changed dynamically | |
| 36 | via a proc file (/proc/asound/card*/pcm*/sub*/prealloc), too. | |

| 58 | The kernel has 2 drivers for the Low Power Engine audio-block on | |
| 59 | Bay- and Cherry-Trail SoCs. The old SST driver and the new SOF | |
| 60 | driver. If both drivers are enabled then the kernel will default | |
| 61 | to using the old SST driver, unless told otherwise through the | |
| 62 | snd_intel_dspcfg.dsp_driver module-parameter. | |
| 63 | ||
| 64 | Set this option to Y to make the kernel default to the new SOF | |
| 65 | driver instead. |
