No dice for me at this stage.
Pairs correctly.
I choose Settings / Sound / Output … Bluetooth - with “A2DP Sink”.
The “Test” button half-worked once. Half-worked means that it showed a Mono speaker to click on to test but no sound came out of the speakers on the host computer.
Thereafter the “Test” button didn’t work at all. No speaker to click on.
I know that this functionality works on the host computer because it works with my existing phone.
