|
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 zero as we need no preallocation.
|
|
|
|
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.
