Windows 10 Playback Device does not Automatically Change When QC35 II Headphones Connect
I've been working with my Dad on his computer trying to get this to work, and so far have had no luck finding a workable solution with Google or the Bose forum.
He has a Windows 10 PC, with Bluetooth built into the motherboard (An Asus ROG Maximus X Hero Z370), and a pair of QC35 II Headphones. The headphones correctly connect and disconnect to the Bluetooth radio of the computer (and appear in the Bluetooth devices list), but when they connect, they do not automatically become the Audio Playback device, and still appear as disconnected in the sound tool bar.
Once they are connected we can go into the Sound window, Right Click on the "Bluetooth A2DP Stereo Audio" Device and Click "Connect" in the drop-down menu, they will become the Default Device in the Sound window, and computer audio will start playing through the headset.
When he turns the headset off, the computer speakers automatically take over; but when he turns the headset back on, the audio won't automatically transfer to the headset, and we have to go back into Sounds to get the audio playing over the headset.
He's update the QC35 Firmware, and we've tried driver updates and reinstalls with no luck.
If anyone has any ideas, we would be grateful.
