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>
