Hi, for the last two years I was able to run the excellent and floss jitsi-meet videoconferencing tool using the jack audio server by installing the "jack" alsa plugin, and telling jitsi-meet to use it as default via my ~/.asoundrc holding the following: pcm.!default{ type plug slave { pcm "jack" } hint {description" jack with software conversions added by me" } } Since the last two or three jitsi-meet upgrades (which are hard to trace because they happen forcibly and in the background without user notification) the software will lose its microphone input a few seconds after the mic is unmuted, tracable by a vanishing audio connection in jack's gui qjackctl. When this happens I see jackd posting subgraph starting at alsa-jack.jackC.468772.0 timed out (subgraph_wait_fd=17, status = 0, state = Triggered, pollret = 0 revents = 0x0) 09:27:13.048 JACK connection graph change. **** alsa_pcm: xrun of at least 393698.976 msecs 09:27:13.052 XRUN callback (8). 09:27:13.232 JACK connection change How can I go about debugging this further? Thank you a lot! P
