Regression from flame behavior, poor ux.

Comms triage: The Flame is still the only reference device, so this issue won't block certification. However, for a high-end phone, this sounds cheap. This might be related to the integration with the audio hardware. What do you think, Gabriele?

Smells like bug 1166758, my take is that this must be a driver issue of some sort. Note that I've previously checked if this was related to excessive CPU usage in a low power state while playing MP3s but this was disproved in bug 1166758 comment 15 and in this bug there's no decoding involved so it can't be that either.
