New description: 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: {{{ D: module-rtp-recv.c: Updated sampling rate to 47506 Hz.
