Airplay connection to Beoplay speaker not working
Hi all,
I am running a Macbook Pro late 2011 on macOS Sierra and since some time cannot connect anymore to my B&O Beoplay speakers via the sound system menu (Airplay connection from iTunes of the same computer works perfectly fine, though). This connection used to work before, I used it to cast the sound of videos on the same speakers. I rebooted everything including the router, contacted B&O support, who told me to contact Apple support, who were fairly clueless. I suspect the issue is with Sierra since connection works fine from a more recent Mac, but again it used to work with Sierra.
Does anyone have a suggestion?
Many thanks in advance.
MacBook Pro 15″, macOS 10.12
