Audio plays for a while, then gets stuck in a loop, repeating over and over and over and over

[berend]

Looks a bit like #1016825 but I have different logging I think. Pulseaudio has worked better for me for the past few weeks, had it occuring, but as it starts straight after a reboot, I just rebooted again, and then the problem didn't appear. But no after 2 reboots it stays.
