This bug still exists for me. I am on a completely updated system (as of 5 minutes ago), and I also did
sudo apt-get purge pulseaudio && sudo apt-get install pulseaudio as recommended above. This has led to no improvement. Note: It does appear that the bug sometimes 'vanishes' for periods of time. E.g. right after booting up, I might be able to alt-tab between a few apps before sound crackling occurs. Once the crackling occurs, it generally will continue to persist for all further alt-tabs (at least between apps that need to redraw themselves in a non-trivial way, which includes Firefox, Nautilus, gedit, etc., assuming open documents in all of them). -- Over-optimistic buffering in PulseAudio causes underruns (audible stuttering, pops) https://bugs.launchpad.net/bugs/190754 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
