Now I noticed that the legacy driver already addressed it recently via commit 6d011d5057ff ALSA: hda: Clear RIRB status before reading WP
We should have checked SOF at the same time, too...
thanks,

Hi Takashi-san,
Yes you are correct. I tested Chrome v5.4 on a CML Chromebook 'hatch' and realize the SOF does no suffer from this issue because the 'sync write' feature is enabled in hda_init. Soon I can reproduce the issue after turning it off. So I think it's still worthy to have this fix in case we need to disable 'sync write' someday.
