Sign the pc to a.mem or some other source. I am almost sure I was told my customer support that sound from PC does not travel over masterlink. I simply changed to a.mem, and the problem was solved.

>> Does PC result in the BV behaving as a monitor and displaying the PC's screen ?

Exactly. I don't even have antenna connected but see all my favourite channels via internet on a web browser.

>> Does the PC's audio play at that point ?

Absolutely, the minijack audio output from the PC is connected to the 2 RCA inputs in the Beovision which are associated to the DVI input (as mentioned in the TV user guide)

>> What sort of PC is it ?

It is an intel NUC. Extremely small, powerful and silent. I have one HDMI output connected to the Beovision and a second one to a video projector.

You are probably right since I see no other reason why it doesn't work.

I can't help keep thinking about what is then the Beo4 option "AV-PC" intended for?

>> I simply changed to a.mem, and the problem was solved.

I think that in that way I would loose the audio while in "PC" mode.

The PC command does travel over masterlink but your Beosund 9000 is probably to old to understand the command, my Beolab 3500 from 2008 understand PC from my BV7 but my Beolab 2000 from 2003 and my Beomaster 7000 doesn't

Well, normally, if I was running DVD from a laptop, I would have to run audio from the headphone jack to the audio in, (red and yellow pledges on the back of the TV), to take the audio. The Apple TV had an optical out, so if the TV has an optical in, then you could carry audio that way. You should be able to tell the TV which audio to use in the menu, (if there is more than one method).

What make and model beovision is it?

Thanks
