Here’s is what was posted there:
Hmm… being intermittent like it is, and not being external, it could be a timing problem. You could try editing /etc/pulse/default.pa, search for the line:
and edit it to:
‘load-module module-udev-detect tsched=0’
If there’s any options past “detect” then just comment the line out (so you can restore it if needed) and add the new setting below it.
You’ll have to reboot to be sure the new setting takes effect. If it’s a timer/scheduling problem that should take care of it, if the problem’s with Pulse to begin with.
