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. Regards, Brent
