Audio outpt doesn't match what's selected

[Bret Ancowitz]

18.04 Ubuntu Budgie
3.28.1 per software center?

I have three sources of sound output: Laptop speakers, USB headphones, and speakers plugged into an external monitor via displayport. On boot, for example, the headphones are listed as the output source in the settings menu, but sound is actually going to the displayport speakers. If I click the speakers, then back to the headphones, all is well. This often happens on boot or after resuming from sleep or lock. Thanks!
