I tried turning off PulseAudio timer scheduling following the instructions on: https://wiki.ubuntu.com/Audio/PositionReporting So far audio hasn't skipped since reboot, but the speaker icon in the drop-down settings in the top-right of the desktop suggests audio is on mute (it is not muted though). I'll see how things go and will try your above suggestion if the 'fix' I've tired already ends up being unsatisfactory in time. Thanks for the speedy response! Andy
