I have had a Sonos Arc for around 2 weeks now & its not fully setup for surround sound (I'm still waiting for my One SL's to be shipped) I knew the issues with the Arc & its incompatibility with DTS, however I came across this article which states that if I turn DTS/DTS-HD to PCM on my Panasonic UB9000, my eARC TV will be able to convert DTS/DTS-HD audio to Dolby Digital 5.1. Am I reading this correctly & has anyone tried this?
DTS via PCM?
Keep Anynet+ enabled and HDMI eARC set to Auto.
Try setting Digital Output Audio Format to Auto or PCM.
Set MPEG Audio on the Panasonic to Bitstream.
What HDMI cable are you using to connect the Panasonic to your TV?
On the Panasonic, set BD-Video Secondary Audio to off.
Is Anynet+ enabled on your TV?
What other options do you have for the HDMI eARC and Digital Output Audio settings?
What specific disc/movie are you testing?
BD-Video Secondary was already off.
When I disable Anynet+ it loses the Sonos Arc & turns off the HDMI-eARC Mode?
HDMI eARC is either off or Auto.
Digital Output Audio Format is PCM, Auto or Passthrough.
I have tried this with standard Region A Blu-ray a of The Silence Of The Lambs & The Thing, which both have DTS tracks?
On the Panasonic, set BD-Video Secondary Audio to off.
Is Anynet+ enabled on your TV?
What other options do you have for the HDMI eARC and Digital Output Audio settings?
What specific disc/movie are you testing?
Tried all the settings, but I couldn’t get it to output correctly.
All I get is Stereo PCM?
On your TV, set HDMI eARC to 'Auto' and Digital Output Audio to 'Passthrough'. Then set your Panasonic to convert DTS to PCM and you should be good.
I’ll give that a go….
Thanks again for all your help, its really appreciated….

Even though you don’t currently have your surround speakers set up, the Sonos app should still already be showing “Multichannel PCM 5.1” or Multichannel PCM 7.1” not “Stereo PCM” from DTS-encoded discs.
What are your TV’s audio settings set to?
Not 100% sure, as I am at work as I type….
I will check when I get home, but I could swear that whenever I have played a DTS Blu-ray the S2 app has displayed Stereo 2.0…. What should my TV settings be for this to work?
My Panasonic Blu-ray Player is still set to Bitstream at the moment, as I had no idea that changing it to PCM would make this change….

What are your TV’s audio settings set to?
If your TV is equipped with HDMI eARC, the Sonos Arc should play multichannel PCM surround sound through all your speakers. On a 7.1 mix, only the side surround channels will play out of the rear surround speakers because of the downmixing issue, but a 5.1 mix will play all the channels correctly.
What TV are you using?
Thanks for confirming, much appreciated. At least I can achieve surround sound now with my many DTS blu-rays….
My TV is the Samsung Q80T QLED….

The Panasonic player will convert a DTS-HD Master Audio or DTS:X soundtrack to multichannel PCM not Dolby Digital 5.1. The Sonos Arc supports multichannel PCM audio although there is an issue where the Arc is not downmixing 7.1 PCM to 5.1 PCM properly. Sonos is working on fixing this issue.
So the Arc will still play the correct surround sound through all the speakers, just not in Dolby Digital?
At present I am only getting 2 channel Stereo from any DTS disc….
