interesting - I removed the null-sink line - rebooted and tested and it worked. so all I have now is: # Forward 11000 UDP to 9875 for pulse audio socat UDP4-RECVFROM:11000,fork UDP4-SENDTO:localhost:9875 & pacmd load-module module-rtp-recv sink=rtpsink sap_address=239.168.3.10 Thanks for the suggestion!
