good question, I've asked this before, and never quite been confident in the answers given. Part of the reason is that seemingly very few require the scenario you describe (although like you, I use that audio sharing reasonably often). Both of my current BV's are on the same B&O platform version as yours. When the Eclipse came out, and I asked this question, I was told by a couple of respondents that the older menu / settings option of "share audio from video sources" was not there anymore. My dealer (though I havent asked the q again for a while) last said to me it was possible - but I'm hesitant. While he (if I remember) can get it to work in the store, I think that is for internal video sources (like a YT video from the Eclipse LG YT app) - but I'd want to see it also work for video sources connected via HDMI. I'm popping in to my dealer on Friday, so I'll see what I can test out myself on the newer BV's.  

You gave me flashbacks to the time I went into my dealer to look at the BV14.  They assured me that I could use my Moment in an integrated setup, but when I asked for them to demo it for me they declined, which tells you everything you need to know.  I never did upgrade to the BV14 and it seems like I dodged a bullet in the end.  Hopefully your experience will be more positive.

Ok, Eclipse 65 owner. I run a Melco audiophile NAS as it is DNLA compliant. My Auralic systems and compatible  Beosystems pick up on the Melco via my home network. The Eclipse monitor (LG) has a built in media player that can connect to this NAS and things like your laptop if networking is shared.

I think Andy's question is different to music sharing across rooms. Like me (unless I am sorely mistaken) the question is that if a BV Theatre setup is playing a video source (be that live TV, Netflix or whatever),  can one chose a BS2 or A9 (for example) in a different room play / join the audio part of the video/live Tv playing elsewhere on the BV Theatre. That is / was possible on BV10/11, BV12, Avant etc (i.e those on the BS4 platform) - those BVs have a menu setting for "share audio from video sources". Being still on an older BV, like myself, Andy is asking whether that functionality is available on the Theatre.   I actually dont know whether it is available on the Eclipse / Harmony either, or whether that option was removed. Its a use case I take advantage of reasonably often - for example if I'm watching the news, or the cricket etc on my living room BV12-65, I often go into the kitchen and just tap my BS2 which will then pick up the audio / sound from the BV12. i.e Network Link took care of everything. I'm popping in to my dealer on Friday, and will try and test out this specific scenario

Hi, I thought I answered this as intended. 1. Devices (confirm Eclipse, not Theatre yet) need to be DNLA compliant 2. Audio devices have their radio but I think it is all shared via the BeoApp. 3. You can join TV sound to an A6 or Essence in other rooms via the App. 4. The Eclipse music player is in the LG Panel - not the sound bar. Sound bar is one part of the distribution, 5. I’m sure this is all more so with Mozart platform but 5he DLNA is the key in my opinion

Must be me then, though I dont quite see why DLNA is relevant to the scenario in question. Anyway, I asked Mike (of the podcast) about the Theatre and getting other devices (he has things like M3's and BS1's) to pick up the audio part of a TV broadcast playing on his Theatre. He's had his Theatre at home for about a week now, and will test it out today. I'll come back with his answer. The answer may not be as comprehensive as Andy / I would ideally like, as he will only be able to test this for sources internal to his Theatre/LG setup, as he has no external video sources connected via HDMI into the Theatre. So while internal video sources may distribute (their audio) to other products, to fully replicate the functionality of the BV11 (for ex), then we'd need to see it work for external sources too.
