I worked on enabling audio on nothing-spacewar on and off for more than three months and I got tired of it. I will now move to something else

This PR contains my WIP code and my findings, hoping they will be useful for someone else.

Current status:

  • Speaker/Earpiece work with stereo sound
  • WCD codec enumerates but gives no sound (mic/headphones)

Key details

  • Commits a93107c and aa36d88 for FP5 audio break audio for spacewar, reverting them make the speakers work. These two commits won't be necessary in the future thanks to Val's driver fix
  • Speaker/Earpiece playing L/R channels works by specifying the sound-channel in the smart amps section of the DTS.
  • Microphone record stream never starts unless 102c363 gets applied, maybe the ADSP expects a stereo stream that never arrives.
