Hello, As a rookie programmer I've never submitted a patch back to a project, however I recently made a small change to the PulseAudio RTP sender module to meet my requirements and I'd like to submit the change for consideration if it helps. I have been using PA to multicast across different routed subnets and I found that the session description packets weren't traversing the routers because their TTL was set to 1. As a recent change to specify the TTL in the module configuration fixed this issue for the actual RTP packets, I just copied the same conditional statements in the module-rtp-send.c file. I hope the attached source file makes things clear - the additional lines are 299-303. Kind Regards, Tom Bamford
