I also have this problem after the latest update from yesterday. I play music over bluetooth and regardless of only listening to music or skipping through songs after some time the audio signal is gone. The playback proceeds, new song informatikn gets send when i skip to the next track, play/pause is working but no audio is being sent. Disconnecting and reconnecting my car stereo fixes the problem for some time. It seems that this happens faster when I skip songs as when I only let them play.
