I'm dealing with a pinched nerve in my neck, so I was trying to switch from my heavy Corsair Void gaming headset to a much more light weight pair of bluetooth exercise headphones (from Letscom.) These same headphones output sound crystal clear from my phone, but when I tried to boot the game today, I finally got hit with the garbled audio bug.

My regular sound bar speaker (from Reddragon) and my Corsair Void headset do not have this issue.

So there's something specific being lost in translation from the game sound to the bluetooth sound driver on my computer.
