Airplay under Big Sur

Hi,

I have Airplay devices from 3rdParty vendors (Sonos) which are recognized from my MacBook Pro with Catalina but the MacBook Pro of my wife with Big Sur does not show the Airplay device since she upgraded.

Is there any bugfix release planned to fix this issue?

Thanks,
Thomas
I have the exact same problem but with Audiopro products.
