 Looks like this bug is back again in 20.10 (https://bugs.launchpad.net/ubuntu/+source/alsa-lib/+bug/1865499).   I was not able to reproduce in the few minutes I tested Ubuntu 20.10, but it's bad enough in Kubuntu that I am considering re-installing 20.04.... I will file a new bug or re-open this bug later today (when I am supposed to be awake...).
[12:20] <BluesKaj> Hi all
[18:55] <Kanedaaa> hi. does anyone knows when this anoying bug https://bugs.kde.org/show_bug.cgi?id=404286 will be fixed in kubuntu 20.04?
[21:56] <Mamarok> Kanedaaa: this does not depend on us but the KDE translation team, they release the fixes. It says the bug is fixed, but not if it is indeed fixed in the official sources upstream, that we depend upon. I suggest you ask the main translation team of KDE (the general translators list, not the Polish one)
[21:59] <Mamarok> and to see any fixes in 20.04 it would have to be backported, do you have the backports PPA?
