help
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 S/G allocation works
and no preallocation is needed in most cases.
Note that the pre-allocation size can be changed dynamically
via a proc file (/proc/asound/card*/pcm*/sub*/prealloc), too.

help
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.
