Public bug reported:
Sound stops(and starts) working from time to time with no definitive
cause, it usually doesn't happen while something is playing so this
makes it harder to find the cause.
It happened once after resume from suspend(STR), restarting fixed it.
Another time it happened after unplugging the AC adapter and turning on the
hardware WiFi button, suspending to RAM and resuming fixed it.
