 Description of problem:
 When I start playing sound over RTP multicast everything is fine but sound
 quality degrades over a few minutes untill it just becomes a skipping
 sound.
 When I log out and back into the client desktop again the sound is okay
 again.
 Local audio is not affected and continues to play fine

 This is the output from pulseaudio -vvv where the actual skipping starts:
