Great news. So i think I will go ahead with this solution ($$ 👍 ). Thanks all for your inputs. No pun intended. Now just need a place to park this!

Anyone try the projector out trick as another option to see if it works as well 😁?

🙂 When you will choose an Apple TV for the music, you know that you can easily achieve full control with a B&O remote right? That would be quite elegant: switch on the set, choose what you want to listen to and P-MUTE the screen, all with (for example) a Beo4. Ideally there is an Apple TV PUC (peripheral unit controller) list already available in your BV7. Have fun! Would be nice to see pictures when you are done!

Wow.  Great to know.  I'll investigate this! Thanks Johan. 

BTW.  Does the DVD drive play audio CDs? Can you check for the P.MUTE working with CDs for me as a last check!?

Hi, good question! I tried, and yes that works perfectly 🙂. I was not aware of this, but very pleased to know now too! It means I can play CDs in my home office.

I do have a question in return (probably for other members following this thread): my BV7 is MasterLinked with a BeoCenter6, can I play the sound of a CD playing in the BV7 over the speakers of the BC6? What Beo4 commands do I use?

Thanks Leosgonewild, I tried but had to test some other button combinations to make it happen..

I finally made it work with LINK-AV (under LIST) and DVD commands. BC6 is in option 6.

I am really pleased with this (for me) undiscovered feature!
