Choppy audio playback while switching between primary/deep buffer streams

[lambdadroid]

Audio playback is choppy for a short file while switching between long running audio ("deep buffer", e.g. for music videos) and short running audio (touch sounds, notifications, ...). This causes weird sounds while starting a video or when receiving a notification while sound is playing.

For now, a good workaround is to reduce the number of those short running sounds. I.e. it can be avoided most of the time by disabling touch sounds, and eventually disabling notification sounds.
