Is audio lag on Bluetooth headphones normal? I continue to play CODMW2 Spec Ops after all these years, as I love them. I’ve recently tried to play with a couple of pairs of Bluetooth headphones, but find that the audio is a slightly out of sync with the game play when I do. So when I shoot, the gunshot sound is half a second or so after I click the mouse. Go back to my desktop speakers and everything is fine. I’m currently wondering if its my USB Broadcom BCM20702 Bluetooth adapter, and whether I need to invest in a more modern one, or if its the old game causing the issues.
