It seems that this problem is solved in libpulse0 1:8.0-0ubuntu3.2. Reiner, I advise you to first update the package list
sudo apt update them try to remove the package libpulse0 to reinstall the new version, by following a similar procedure (I didn't try, so it's a blind shot). #1 purge the package sudo apt purge libpulsedsp pulseaudio libpulse0 libpulse-mainloop-glib0 pulseaudio-module-x11 pulseaudio-module-bluetooth pulseaudio-utils #2 keep track of the additional removed packages #3 reinstall the pulseaudio packages to the newest version. Add at the end of the list the packages removed at step #2 sudo apt install libpulsedsp pulseaudio libpulse0 libpulse-mainloop-glib0 pulseaudio-module-x11 pulseaudio-module-bluetooth pulseaudio-utils #4 Remove the user config file rm -r ~/.config/pulse/* #5 Shutdown the computer then turn it on again (don't reboot). I hope it will help. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1643847 Title: Ubuntu 16.04 no sound after change volume To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/1643847/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
