Correction, you don't need to spam spacebar. It just happens sometimes.
I don't know how to send images through reddit. I didn't know about + can't find Origin audio settings. Could you clarify on which PC sound settings you're talking about?
If it helps, I'm using the Sony MDR-XB950N1 Bluetooth headset. It shows up as two different output devices, Headset and Headphone. Headphone is set as default output. Headset is set as default communication device. At time of startup, Windows Sonic for Headphones was on (not sure why it was, actually).
A separate issue I was having were audio hitches, but after I turned off Windows Sonic they disappeared.
I have heard a few instances of bluetooth causing issues when used. Are you able to test with an analog (old school) cable?
