Urgent workaround for M16 ChromeOS bug.

I suspect it is caused by low latency audeo on the slow hardware.
While attempting proper investigation I just turn off low latency
audio on ChromeOS for now.
If it is really the case I se several ways to properly fix the bug,
but they require much more testing and experimenting.
