Comment 173 for bug 1563110

@Takashi: Thanks for working on it, I tried topic/asus-e100h-4.10
on Asus E200HA:
- firmware load fails when driver is built-in,
  need to set CONFIG_SND_SOC=m to get CONFIG_SND_SOC_INTEL_SST=m
  so it is loaded after / is mounted
- looks good in /proc/asound
- tried to play a wav file with aplay and an mp3 with mpg321
  and both failed
- alsamixer looks pretty confusing to me (many controls, but
  only two are visible in one screen so lots of scrolling needed)

some dmesg FWIW:

Not sure if any of this is useful to you but I just wanted to let you know.
