[PATCH] player: automatically pause if last sink dies

[Eric Wong <e@80x24.org>]

Attempting to play (and fail) every song in the queue or
tracklist is not ideal when a the USB/HDMI cable to the sound
device gets unplugged by accident.

When tee-ing to multiple sinks, we will still gracefully continue
if one goes dead and there are remaining sinks.
