12 hrs testing which i did on pulseaudio-11.1 are without my
modification. The basic modification which i made in the
previous pulseaudio-8.0 is with the idle state of
bluez_source card (i.e., card is vanishing when the song is
in the pause state) and did some changes to buffers of
pulseaudio to reduce the latency. But in pulseaudio-11.1 i
didn't do all the changes as i didn't find any initial
latency. but periodic latency after 12hrs still exists. The
issue is reproducible with Gstreamer also. </div>

What output does module-loopback give when you run with debugging?<br>
Do you see the growing latency there? Does it show up with pactl
list sinks<br>
or pactl list sources? Any error messages in the PA log?<br>
<br>

One more comment: It may well be worth trying 12.2 because the
bluetooth thread<br>
function has changed.<br>
