Public bug reported: TL;DR: https://askubuntu.com/questions/995281/audio-devices-disappear
Brief Version: My version of Kubuntu keeps losing audio devices/audio and cannot recover, including after reinstalling pavucontrol, alsa, etc. I can't figure out how to get this to stop, and is a certain... and very persistant bug. I've tried multiple uninstalls, and reinstalls, and occasionally, one day after restarting the system, the audio bug is present and never goes away again. All attempts to raise volume don't work that I've tried. The askubuntu page has more detail, including my hardware specs. ** Affects: kubuntu-ppa Importance: Undecided Status: New -- You received this bug notification because you are a member of Kubuntu Bugs, which is subscribed to Kubuntu PPA. https://bugs.launchpad.net/bugs/1745510 Title: KDE Loses Sound Devices/Audio To manage notifications about this bug go to: https://bugs.launchpad.net/kubuntu-ppa/+bug/1745510/+subscriptions -- kubuntu-bugs mailing list kubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
