0029 Specifies the default pre-allocated buffer-size in kB for the
0030 HD-audio driver. A larger buffer (e.g. 2048) is preferred
0031 for systems using PulseAudio. The default 64 is chosen just
0032 for compatibility reasons.
0033 On x86 systems, the default is zero as we need no preallocation.
0034
0035 Note that the pre-allocation size can be changed dynamically
0036 via a proc file (/proc/asound/card*/pcm*/sub*/prealloc), too.

0058 The kernel has 2 drivers for the Low Power Engine audio-block on
0059 Bay- and Cherry-Trail SoCs. The old SST driver and the new SOF
0060 driver. If both drivers are enabled then the kernel will default
0061 to using the old SST driver, unless told otherwise through the
0062 snd_intel_dspcfg.dsp_driver module-parameter.
0063
0064 Set this option to Y to make the kernel default to the new SOF
0065 driver instead.
