|
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. |

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