I’m having similar problems.

Using Final Cut Pro I switch from external speakers to internal speakers easily.

Premiere has been buggy on some minor issues so I’ve tried re-installing, getting new drivers from Blackmagic (I only use this for external output), etc. But most annoyingly is when switching audio. I go to Preferences>Audio Hardware> Default Device> .. and changing the Blackmagic Audio to System Default (ergo the headphones) the Software crashes. Repeatedly.

Anyone else having this issue? All I want to do is to switch from headphones to external speakers — but Blackmagic only allows external speakers. Perhaps there is another way.
