  29           Specifies the default pre-allocated buffer-size in kB for the
  30           HD-audio driver.  A larger buffer (e.g. 2048) is preferred
  31           for systems using PulseAudio.  The default 64 is chosen just
  32           for compatibility reasons.
  33           On x86 systems, the default is zero as we need no preallocation.
  34
  35           Note that the pre-allocation size can be changed dynamically
  36           via a proc file (/proc/asound/card*/pcm*/sub*/prealloc), too.

  58           The kernel has 2 drivers for the Low Power Engine audio-block on
  59           Bay- and Cherry-Trail SoCs. The old SST driver and the new SOF
  60           driver. If both drivers are enabled then the kernel will default
  61           to using the old SST driver, unless told otherwise through the
  62           snd_intel_dspcfg.dsp_driver module-parameter.
  63
  64           Set this option to Y to make the kernel default to the new SOF
  65           driver instead.
