The Beam can only play the audio when the TV itself passes the audio stream to it. There are a good many TV's that pass that audio in good time and there are one or two models that cannot process a 5.1 stream quickly enough to keep the audio in sync with its own video, particularly if the stream is passing through from one HDMI port and out to another.



Some users have resolved such issues with updates to a later version of their TV firmware. Some have resolved it by switching off enhanced audio features, such as Dialog Clarity, 3D audio, TruSurround HD etc. Some have found the audio 'pass-thru' to their TV optical port is slightly faster too, for some reason.



So it maybe case of trying some, or all, of those things to see if it fixes your lip-sync issues. I would start by switching off any Samsung’s enhanced TV audio features.

Thanks Ken_Griffiths I'll have a look in the TV menu but from what I noticed before there were not many options. It seems that £399 is a lot for something I won't be able to use ARC benefits. My TV is quite a basic model and it's probably more a Samsung issue. But no point keeping the Beam if it doesn't work properly with it.

I would also try experimenting with optical output from the TV, via the Beam's optical-to-HDMI dongle. If that Samsung's anything like mine the optical can be moved forward somewhat -- i.e. ahead of the picture -- and can help compensate for any additional delay.

Thanks ratty. Is the optical-to-hdmi dolby digital?

Yes it will support DD. You can always check what the Beam's receiving, by looking in Settings/About My Sonos System.

There are workarounds and that is to get an audio extractor/switch. Then instead of cabling the video source to pass-through the TV, you cable it direct to the audio extractor instead. Then cable the TV and Beam to that switch.



I’ve never tried these things myself, but many users here in the community use that method to by-pass their TV and I believe it works well in almost all cases.



These are two links to products I have found in other threads here, but you may want to research this further before deciding to go down that road. It’s not something I’m am too familiar with myself...

jonezeeee,



You will need to look for an audio extractor/splitter that supports Dolby Digital 5.1 output. I think that’s fairly obvious and I’ve seen that mentioned in a few threads. I just wanted to add I’m not recommending either of the two products in those links in my earlier post, so treat them just as examples.
