I've just got a new PC, and when connecting my bluetooth headphones (Mpow 059) the sound is really muffled and distant sounding. I used these on my old PC (also windows 10, with the same mpow bluetooth adapter) and it was fine. Also my headphones via 3.5mm jack sound fine on this PC.
In the sound mixer there are two options: Headset (MPOW-059 Hands-Free AG Audio) - this works but sounds muffled Headphones (MPOW-059 Stereo) - this has no sound at all
My mobo is Gigabyte B450.
Any help would be appreciated
