Losing the will to live here. I Have Sonos Beam Gen2 and I cannot have any sound other than stereo pcm. My tv is PHILIPS - 50PUS7855 50" 4K . I have a hdmi 4k cable. I am using both the standard TV, Netflix and 4k blu Ray player and they're all playing stereo pcm only. I have set the audio to multichannel (bypass). Why is this happening?
Any help greatly appreciated.

It’s probably going to be easier to maybe speak with Philips Support Desk, as I’m sure this is a TV Settings issue, but …

The last won’t work. Sonos needs HDMI-ARC that the Nvidia does not do.
What do u mean ? Nvidia shield has no HDMI out connection? I checked on the web it does
No, the Shield (I own one) does not have an HDMI-ARC output, so sends it’s audio to different pins on the connector. You cannot get sound on a Sonos soundbar connected to a “normal” non-ARC HDMI connection. So connecting an Nvidia “directly to soundbar” wil not work.
Thanks Ken, could not have done that without you. Much appreciated

Pages 40/41 cover the TV audio settings, you need “Multichannel bypass”.

No. The Sonos input is only on the ARC/eARC pins, and not the standard audio pins for HDMI.

So the Sonos doesn't have HDMI/ in on it's side for direct connection to devices?
No. It only has one HDMI port, meant to be connected to the (e)ARC on a TV.
Bought a LG g series and the beam 2. Have shows and films with atmos and while the sonos is connected via the earc and the output is though the sonos, I cannot get the app to display anything other than showing stereo pcm. What the hell is going on?
The usual sound settings to go with on the LG TV are:
I did try the optical cable also by the way, same issue
Hi, thanks for your reply. I can confirm yes to all of the above except tv speakers off. The options are hdmi sound system or TV speakers off, it only works if I have hdmi sound system selected. What else could it be?

Ok I understand, I do not have a shield device with me. But on another occasion I have read a post in a forum that stated that a soundbar had no sound in HDMI arc but once they connect it to the normal HDMI in port they had sound

Your profile says you have an Arc: does yours have one?

Well It's part of the requirements to register. But I wanted to just answer the author's question
On further investigation 'personal mode settings' is completely greyed out and I'm unable to select
I have the same kind of phillips tv The sound personal modes are for the Tv speakers. When the TV speakers are off they will naturally be greyed out due to HDMI sound system being connected because now yr tv is outputting sound to an external audio system
I did already. It allows me to turn the TV speakers off but the same issue, only sound is stereo pcm
multichannel option does is encode audio to common format like 5.1 or ac3.. watever yr soundbar understands
Multichannel ( bypass) does not re encode the source audio but sends out the bitstream to the soundbar or receiver. If u choose DD+ or atmos and u choose bypass option but yr soundbar do not have DD+ or atmos , u will have no sound because the Receiver in yr soundbar does not understand these formats when its sent the bitstream
the last option stereo uncompressed sends 2 channel PCM to the soundbar ( i am not sure if the tv somehow re encodes or downmixes dolby to stereo ect>)
Since HDMI ARC cant do 5.1 /7.1 uncompressed multichannel PCM ( LPCM) ony stereo uncompressed is possible
Sound out settings. Can confirm all above is correct also

Personal mode settings is greyed out, as you can see in this photo. When the sonos
Thanks for the info. How did you get around this? Do I need to buy a new TV or are there settings that work? I still haven't fixed
When the sonos was powered off and the sound was coming through the TV, the personal mode settings was not greyed out and I could access the options. Soon as I power sonos on, it is greyed out?

I do not have Sonos. Only Yamaha SR-B20A. But since this topic interested me I replied to clarify things. With Phillips TVs, there is confusion in the audio settings of the tv because they do not have options to select the type of sound like LG or Samsung tvs.
It's more of automatic settings but I have tried 3 soundbars , 2 of them high end ones on the tv and all of them do work in either one of the 3 options available in the tv audio settings.
Multichannel option is for soundbars that do not understand specific formats so the tv will output by downmixing to general dolby digital 2.0 or ac3 core by stripping out the specific metadata from DD plus or Atmos to solve compatibility issues.
The multichannel bypass option is for av receiver or higher end soundbars and standalone receivers with Atmos , DTS X or DD plus I am not sure why the Sonos behaves in that's way but to me it looks like it only outputs stereo (2.0) even though in the website it's stated that it does a variety of multichannel formats. I think it's a sonos firmware problem OR I think it only outputs multichannel sound in E-ARC connections . ( Came across such discussion in other forums about the Sonos firmware defect)
I have the Yamaha soundbar (SR-B20A) supports Dolby digital and DTS multichannel formats and outputs in virtual surround . I assume the Sonos is only giving pcm 2.0 which is why u getting only stereo? In this case u are getting stereo uncompressed which is a pcm signal. It should be clearer in quality than Dolby digital 2.0 or 5.1 which are equivalent to compressed audio like mp3 or AAC . So the problem here is yr Sonos . In my Yamaha soundbar when stereo uncompressed (PCM) is detected , the sound bar applies pro logic 2 to give a surround like effect which in my opinion works great too .
As to yr question, yes the only solution is multichannel or stereo uncompressed should able to work with Sonos if u have ARC only Phillips tv. The other alternative is to get different soundbar like LG or Samsung or JBL with Dolby Atmos or DTS capability to output surround sound or an E-ARC TV for Sonos.
Is HDMI3 an output or an input channel? It looks to be a “source” rather than an audio output.
Actually I'm not sure what this means. I'm not very technical! How can I check / should I plug into hmdi 2 instead? Thank you
Tried on Netflix, sky, and 4k blu Ray player with dolby selected within the settings of the blu Ray player. All has the same result. When I initially setup a few weeks ago I did see dolby 5 in the sonos app but I can't for the life of me get it to return. I would be happy with that even if I can't get dolby atmos. I didn't pay this money to listen to stereo
Does the Sonos remote or app had options to choose stereo or other surround formats? If u had chosen stereo in the Sonos remote or app it will play only stereo. Check that.

If I am not wrong, there could be a problem with the Sonos firmware. Try update it . Since u stated that u were able to get Dolby once , yr settings set in both the tv and devices should be correct .
