Hey Guys, I am using pulseaudio for years now, but since Version 14, maybe 15 there is a crackling in the rtp stream. I've setup RTP just with paprefs, enable the sender and local receiver on a separate audio device. I know that I am reporting this really late and the bug is there for some years now. I hoped this gets eventually fixed, but it did not. I am using the latest archlinux pulseaudio. Are you guys aware of the issue, does it also happen to you? It is just a tiny crackling, but you can hear in on good audio boxes. It sound a bit like the vinyl sound, just not so often. You can hear it on the sender via loopback and on all other receivers as well.
I had a similar (maybe the same?) problem - soft crackling and hissing, almost like old vinyl, sometimes also like a clipping sound effect. Mine was a bug that was resolved in recent versions of pulseaudio, and with the latest pulseaudio version that is shipped with my distribution (Debian), the problem is gone ("pulseaudio --version" shows "pulseaudio 16.1"). The most frustrating part was that it almost seemed as nobody else was hitting this problem, because I could not manage to find anything on google. For a long time I also suspected something related to rtp streaming and/or resampling, but in the end, it was this bug... and as if to proof what I just said ... I cannot find the bug report for it right now ... if I find it, I will amend it to this email string... Cheers, Chris.
