I have just got a Samsung 55JU6000 UHD TV

TV Settings HDMI Audio Format "Bitstream"
Audio Format "Dolby Digital"
HD Audio "On"
Sky Box set to "Dolby Digital"
Sounds Superb
Mike57, do you have the optical cable connected to your tv and the skybox to the tv via HDMI? I'm looking at the Samsung 50JU6500F UHD TV and want to confirm it works with Sonos out of the box. Right now I have an older Samsung that lacks audio pass through to the HDMI sources so I have to use a crappy external converter box.
Hi
I have HDMI cables from my Sky Box and Pioneer Blu-ray to my TV
And just a fibre cable between the TV and Sonos Bar.

What ever I set the setting on my TV it passes the sound through.
Not always sure what it is though.
Sky needs to be showing an HDMI channel
I have a Fleetwood Mac Blu-ray, one side is Stereo the other side Dolby 5.1
The difference is amazing.

One downside I have returned my Sonos Play 1's as they did not seem to add anything, in fact they cancelled out the playbar to a degree.

Thanks
Nice, thanks for the quick reply. Do you have the Sub with the Playbar? I currently have the Playbard and two Play 1s and don't notice the canceling out that you mention but I don't have the sub and am considering adding that soon.

mike57 - did you "bond" the Play 1s or "group" them? I understand that if you group them, they can mess up the sound, they should really be bonded.
Hi, Thank you for your replies.

I do not have the sub yet.
I listened to the Sonos with the sub and play 1 in the shop and they sounded fantastic.
I'm an old audiophile and image and balance were important to me. I never felt 5.1 systems ever sounded right.
The problem I have is that I can't get the rear speakers behind the listening position. They were on the side walls.
As soon as I disconnected the rears the bar came alive. Filling the front and sides with amazing sound.
I think I tried everything, no balance adjustment doesn't help.

I recently bought the LG 55EG920V. Does anyone have experience with this model? DD 5.1 is correctly passed through using HDMI, both from the Netflix app and the blue ray player, not from Maxdom (German's kinda of Netflix). Normal Tv and LG apps pass only DD 2.0 through. With my old Philips I was always getting DD 5.1. should I contact LG? Please advise
Can anyone confirm if the LG 43UH603V will passthrough 5.1 to optical?
I have an LG 65UH770V. I have set my PS to Dolby but it's still sending the signal out as stereo. Is there anything I can do? Please help
BigTim,

By PS, I assume you mean a PlayStation?

If you've set the audio settings in the PlayStation, you should then check the audio settings in the TV set. It may be down converting the signal to stereo.

I have an LG OLED55B6P and it passes through 5.1 no problem.
Thanks Airgetlam

I tried that and still stereo. I've read about changing from PCM to AC3 in the service menu but not sure how to get into it. Will get technician out and feedback.
You're most welcome. I'll be interested in what you find out from the technician.
Thanks for all the replies.

The technician just left. The EDID in the service menu was set to DTS, which he changed to AC3 and that worked. The playstation now plays crisp 5.1 Dolby Digital. The only thing we couldn't fix was my pc which uses Nvidia Geforce driver. My MacBook plays 5.1 but my pc won't. We checked the other settings for the EDID but couldn't sort that out so I assume its a graphics/sound card issue which is a problem for another day.
There was someone else posting a similar issue yesterday, about a graphics card that didn't actually output 5.1 through the HDMI cable. I think he/she replaced the video card with a newer one.

I wonder what the cost difference between the two sorts of chips is.

In any case, I'm delighted that you're on your way.

I have the Playbar and Sub, and just added two Play 1's, and the 5.1 playback from my Tivo Bolt, Netflix via my Sony 4k TV is really nicely distributed. HDMI from the Tivo to the TV, and optical cable from TV to Playbar.
I have an LG OLED55B6P and it passes through 5.1 no problem.

We're any additional steps required to get this working with your 2016 LG OLED TV?

I have the Oled65b6p and this is the only shimmer of compatibility that I've been able to find. Interested in Sonos, but have not purchased yet.

I have the Sony XBR55X900C connected via optical cable to the Sonos PlayBar, Sub Woofer, and two Play 1's and it works great. MyTivo Bolt is connected to the Sony TV via HDMI cable to input all audio and video. I did change the audio setting on the Tivo Bolt under Dolby Audio to PCM only (no Dolby) as per Sonos tech recommendation.

I can confirm that the OLED65B6P DOES support 5.1 pass-through. It required going into settings --> Sound --> then setting the "Sound Out" option to "LG Sound Sync (Optical)" and then setting "AV Sync Adjustment" to "On" and enabling "Bypass". After this, I got 5.1 fine from an Xbox One S (configured with bitstream output via HDMI and Dolby Digital Surround.

Does anyone know if a LG 55LW5600 passes true 5.1 through the digital output?
If this is not too late a reply, then I have a LG47LW5500 that passes Dolby 5.1 very well to the playbar.
So I also have the 2016 LG OLED model. Under my Sonos it is showing Stereo still although I have done all things outlined a few posts above. I do hear like my surround P1's are indeed playing the role of a surround speaker but something must be wrong because as others have said it should say Dolby 5.1 surround under "My Sonos". For reference I have John Wick in right now playing under the Dolby Atmos track. Does it automatically downgrade that to 5.1? Or do I have to have a true 5.1 Dolby track to get the effect? Any help would be greatly appreciated!

Your LG OLED will pass through everything it receives, to the playbar if set to auto. So if any signal other than 5.1 is passed thro, the playbar will produce pseudo surround, stereo, or no sound at all.
You can set the LG sound output to stereo pcm if you are getting no sound, ie from DTS sound tracks from blurays.

Sonos suggest you just use streaming services with 5.1 sound content to overcome problems with physical discs....
Thank you for your reply Paul.

I just do not understand why Sonos is telling me I am receiving "Stereo" when I am hearing all the smaller detailed sounds from to play 1 surrounds. It makes me think I do not have something setup correctly! Any other thoughts, folks?

It is receiving stereo, then processing it and sending sonos simulated surround sounds to the play1s.

2 corrections:
1. The LG must be set to 'Audio Out (Optical/HDMI ARC)' with the optical set to 'Auto', not the LG Sound Sync option.
2. The Xbox must be on Dolby Digital, not DTS.

With bypass enabled per the above, the Sonos controller app should now show 'Dolby Digital 5.1'.


Hello, first of all thank you very much for the answer but isn't DTS better than DD so why we don't select it on Xbox one ? Thank you
