I've contacted PulseAudio developers and with them I was able to confirm that
this is indeed an issue in PulseAudio when using a monitor input in certain
cases. The audio does get heavily distorted (I was finally able to record it)
and that is the reason why WSJT-X is unable to decode the signals.
On the other hand, the distortion issue does not occur always and I was able to
keep WSJT-X decoding FT8 in the background for several hours without any sync
issues. Complete QSOs via bidirectional WebRTC connection to a transceiver
(using an IC-7300) work very well also! The software I'm testing is a ham radio
remote control server written by me...
Thanks for the quick answers!

Hi Mikael,
let's hope the pulseaudio developers can fix this quickly as correctly
working audio loopbacks are essential for SDR users also. Do you know
the "certain cases" are that cause the issue?
