I'm using Premiere Pro Version 13.0.2 (build 38) for Mac OS, and am getting a strange issue where my audio is left-right flipped. Anything in the right channel comes out on the left, and anything in the left channel comes out on the right. The source audio, when I play it in another application, such as VLC, is correctly flipped. I am doing quite a bit of panning to match events in my video, and not having the ability to properly hear the result as I'm editing is confusing.
I've tried playing with the "Audio Hardware" settings to no avail. I've also tried chaning the "MIDI audio" settings int the Mac OS system Preferences, but no matter what I do, Premiere defies the setup.
