Comment 49 for bug 1847570

I also upgraded everything from the proposed repo and tested. This issue is fixed for me as well. I power cycled each monitor monitor (I have two.) in succession, and the output device selected remained the motherboard line out throughout. Line out was also selected at boot, where previously at each boot, it would reset to one of my monitors.

I was previously using the workaround but reenabled switch-on-connect and switch-on-port-available (removed the hashtags commenting them out) prior to installing the new pulse audio packages.
