Sound Issue: No sound through bluetooth headset: fixed.

[slightlysinister]

I've been hunting to fix this problem forever, hopefully this helps some people. If you can't hear any sound specifically in BG3, but all other Steam Games and other programs output, do this.

Open task manager while BG3 is running.
Right click, hit detals.
Click set affinity.
Click the box that says all processors, which will uncheck all boxes, don't hit okay yet.
Click that box again, selecting all cores. Then hit okay.

This immediately popped the sound back in for me. Hopefully this works!
