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.
Ziptbm,

THANK YOU!!!!

I've been trying to get this working for hours! You nailed it! Can't even imagine how much time I would have spent trying to figure it out. Confirmed and working like a charm!
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 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.


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'.

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.

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.

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.
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.
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.
I have fixed this problem on my LG 55LA690V-ZB TV. Basically I wrote to LG support and they sent me the following settings and it now works fine.

From LG support
The Sound Out settings, I would suggest ensuring the AV Sync Adjust is turned on, as well as Bypass.
I would also check that the Sound Output is set to Auto and not PCM, as PCM is limited to 2.1 Sound Output.

It didn't work until I ticked the Bypass box then it worked fine.

Hope this helps
Chris
You're most welcome. I'll be interested in what you find out from the technician.
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.

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.

This is a handy webpage that shows the audio pass through capabilities of some TV's.

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
Can anyone confirm if the LG 43UH603V will passthrough 5.1 to optical?
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
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.

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.
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.
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
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.
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
Thanks again for your helpful and prompt replies. I hope you are enjoying the LG OLED TV as much as the Sonos sound system.
