That's one of the things I wanted to add. When you start playback there
is a 1-2s period where the receiver is still looking at the data to
figure out if it's PCM or compressed, and you lose those 1-2s of audio.
The hw silence mode is a way to keep the link active.
But I guess we can remove first and re-add later so no objections.
