Public bug reported:
just upgraded some of my computers to Ubuntu 20.04, also tried with
fresh install, in all case the pulseaudio rtp receive module is giving
me very poor sound.
Easily reproducible on a single machine :
pacmd load-module module-null-sink sink_name=MyNullSink
pacmd load-module module-rtp-send source=MyNullSink.monitor loop=true
pacmd load-module module-rtp-recv
And then play something in the null sink, loopback sound will be bad
(lags).
What I noticed : if I open the rtp stream with vlc, it's ok, sound is
good.
Ubuntu 20 uses PulseAudio 13.99, aka (I guess) PulseAudio 14 which
implements RTP through gstreamer, which is new.
So I tested my rtp stream with gstreamer:
gst-launch-1.0 udpsrc address=224.0.0.56 port=46586
caps="application/x-rtp, media=audio, payload=10, clock-rate=44100" !
.recv_rtp_sink_0 rtpbin ! rtpL16depay ! audioconvert ! audioresample !
pulsesink
And it works fine, so I definitively believe there is an issue in the
new module-rtp-recv.so bundled with PulseAudio and that is now based on
gstreamer.
