d8b3b4cb6b Check queue empty only once when reading messages.
There was a second is_empty() call hidden in the pop() call, so the while(condition) was redundant.

ae62405344 Simplify audio muting.
Zero out the audio buffer instead of muting the codec. The HPF (and other downstream signal processing) can continue running, not produce discontinuities from being effectively halted during mute.
