Fix the Default audio output for iMac Pro
On my previous iMac and my current MacBook Pro the audio in Premiere and After Effects would switch to headphones when headphones were plugged in and switch back to the speakers when I unplugged, all without having to go up to Audio Hardware in preferences and switching.
Now, on the iMac Pro that is not the case. Each time I plug in headphones, the timeline stops playing and i have to go up to preferences and audio hardware and select external headphones or iMac Pro speakers if I'm unplugging them.
I was on the phone with Apple about this as well as Adobe, and what the Apple rep and I found out is that the iMac handles audio a little differently. When you plug in headphones it sees it as a new audio source while the previous iMac and the current MacBook Pro switches it.
On the older iMac and the current MacBook Pro in Preferences/Audio Hardware/Default Output you see Built-in Output (this will be whatever the output is for the computer it self)
On the iMac Pro in Preferences/Audio Hardware/Default Output you see iMac Pro Speakers and if headphones are plugged in External Headphones. It's reading it as two different sources.
Also, which I think is a complete bug is if you are on External Headphones and you unplug them, it won't play the video any more even if you switch the audio hardware to iMac Speakers, you have to quit (sometimes force quit) and reopen the application.
We anticipate resolving this problem in an upcoming release, and I will update this UserVoice item to “Completed” when the new functionality is fully tested and available.
With newer Apple systems, especially those based on the T2 chipset, many previously singular states of the Built-in audio interface are now exposed as completely different virtual devices by MacOS. One used to be able to plug in a pair of headphones and let the OS re-route the output automatically. Now, this either requires a manual change, or utilizing new frameworks for the same functionality.
Thanks for your feedback, and please stay tuned.
I have this same issue on my Imac Pro. Didnt realize it wasn't just me!

I dont know about windows, i am using MacOS, the hardware choice in premiere is seperated from the audio output of MacOS. In fact, apple itself is automatically switching to the best availible audio output.
Currently driving me nuts. I went to the Microsoft Store and they had me wipe Windows 10 off my computer and replace everything before realizing this was a Premiere Pro only issue: It confuses my Surface Book 2 as to what audio device is even being used. I now have to go in to Premiere's audio hardware preferences to manually select the Surface Dock, say, to hear audio through that... but when I unplug that I have NO AUDIO and a warning that no device is available. I then have to go back into preferences just to listen on headphones or internal speakers! Pleeeease fix, thank you. :)

Audio hardware options: add a first and second choice audio-output option, and let Premiere switch this automatically by availability.
Example of my dream:
I use a bluetooth headphone while editing. When my bluetooth headphone is turned off: Premiere switches automatically to the 'build-in output' (minijack speakers).
When i turn the headphone back on: Premiere knows the bluetooth headphone is my 1st choice, so it switches automatically to the bluetooth output.
By the way, this is the same for AE and probably all software..
