	  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.
