But since this bug below was fixed it seems to have introduced a new bug where the audio ALWAYS comes out of the internal speaker. I rolled back to Unity 2021.1.2 (before the bug fix) and the audio works correctly out of the normal speakers.
If you select both, the sound should play normally, but you can’t get this result This is a problem that spans several versions and has not been officially solved
@marnsmith There seems to be something wrong with our tooling sometimes that is matching changesets to Unity releases. I’m sorry for the confusion this is causing.
It looks like these fixes are actually in 2020.3.38f1 (which is not out yet) and 2021.3.8f1 (which is out).
