Hi Paul,
Make sure your B2 has the 'B2B' version of the software - press INFO on the remote twice to see this on the B2 or click the COG wheel icon on the web UI to it there - so for example B2B Oct 22 2021 - if not please email us on - thebrennanb2 @ gmail . com - no spaces.
I find the web UI is the best way to setup a Bluetooth connection -
Open a web UI page >> click the COG wheel icon >> click the Bluetooth tab >> make sure your B&O is in Bluetooth discovery mode (check the manual for how to do this) >> click 'Scan Bluetooth' on the web UI - you may have to repeat if the B&O is not listed first time >> click 'pair' for the B&O >> when paired, click the 'Out' box.
If the B2 and B&O pair but there is no sound, try clearing all previous Bluetooth pairings from the B&O - check the manual or online for how to do this >> click on 'Reset Bluetooth' >> repeat the above procedure
