I assume you also loaded module-zeroconf-publish on the other machine. Looking at the traffic with wireshark reveals a bit of mDNS chat between the machines and a short burst of packets every 10 seconds. By no means a constant spew. The burst of packets every 10 seconds is probably due to module-tunnel requesting the latency of each sink. It's not a lot of traffic though. > This happens regardless of whether there is sound being played or not. Hmm, this really sound more like you have activated rtp-send. > Is this really normal and expected? Well, other than what I described above, I can't reproduce it here, so it would probably not be expected. Could you look with wireshark to see a bit more clear what the packets are? BTW, a wireshark protocol analyzer for the native pulse tcp protocol would be awesome. > Cheers, > b. Maarten
