AirFloat connection silently fails after muting sound for a few seconds

[3rd3]

This happens both with my iPad and iPhone on iOS 6.2. My computer runs OSX 10.9.1.

After pausing say a video for a few seconds (30-60 sec.) the connection stops and I’m unable to reconnect. I need to quick AirFloat and reopen it to make it work again. I can pause for short time periods (for example 10-20 seconds without trouble).

It gives this message in the log files:

But the sound comes from the internal speaker although the iOS is selected as output device.

Sometimes it even crashes during playback:
