Hello again. I have used pactl subscribe command and i think that in the moment of sound interrupt there are the corresponding lines:
"Event 'remove' on sink-input #353
Event 'new' on sink-input #358
Event 'change' on sink-input #358"
As for journald i have a lot of such errors, but they don't influence the audio quality:
"Mar 11 22:20:13 deb wireplumber[1357]: RFCOMM receive command but modem not available: AT+XIAOMI=1,1,102,85,88,27,174"
There are some other mentions of the bluetooth/headphones, but they don't meet the moment of sound issues. Full journald -f log is in an attachment.
I must say that i had an opportunity today to test a laptop with Debian 12 XFCE laptop with Pulseaudio and the problem is the same there. But, as i said, on a laptop with Linux Mint XFCE everything is fine. That's strange. What is the main difference between Linux Mint and Debian here..?
I also tried Liquorix 6.7 kernel but it didn't help.
Thanks.
