Set the audio device to the null-device after endpoint initialization.

This prevents the audio-thread from hanging if nothing has been played
on the alsa device, which manifests in only being able to receive a single
call (which has some audio played).

The problem is, that the audio bridge fires up a thread, that waits on
snd_pcm_drain(), which does not seem to return if there has been no data
on the pcm sink.
