I'd start from checking if there's anything printed to Pulseaudio log when the skips happen. Open a terminal, then enter these commands: echo autospawn = no >> ~/.pulse/client.conf killall pulseaudio LANG=C pulseaudio -vvvv --log-time Then start playing something. Then press enter in the pulseaudio terminal window a couple of times to get some emtpy lines in the log. Then wait for the problem to happen. When it happens, check the terminal window - what has been printed to the log after the empty lines? If you can reproduce this by doing absolutely nothing, then you can stare at the terminal window all the time to make sure that whatever is printed to the log, it is actually printed at the same time when the skips happen. -- Tanu
