Audio is not working for me as well. I said before that audio was working
because I tested with the headphone audio jack but I forgot that I had
re-introduced the clk_ignore_unused parameter to my kernel command line
to test the mmc/sdio wifi. Without clk_ignore_unused, I have no audio.

I see that the downstream daisy_max98095 ASoC driver in the ChromeOS tree
grabs some clocks that the mainline sound/soc/samsung/snow.c driver so it
it seems that at least that is missing and may explain why it is working
with clk_ignore_unused.

Best regards,
Javier
