I was wrong sudo apt-get purge pulseaudio && sudo apt-get install pulseaudio ubuntu- desktop
Has not actually worked, the situation has improved - I did lots of alt tabbing with cpu hungry programs running and it was fine. The problem appears to not be high CPU usage (at least on my machine) instead when there are large changes in RAM usage there is a brief pause. At least I don't have the crackling and distortion I got towards the end on Gusty :-) -- 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
