If this was the stock setup I would share articles on how to select the audio output in Windows. But now with the mucking with the drivers all bets are off.
Bluetooth connecting does not mean the audio will go to that. It only means we connected. There's another step that varies with versions of Windows (I missed which here) so here's a fair tutorial on the steps after the pairing.

Notice the trip to Speakers in control panel?
