Hi guys, I have an issue with my Sonos arc with DTS audio, for example when playing a Harry Potter movie I have to change the settings to PCM in the bd player, and then the audio then works but it's only in stereo PCM which is a bit rubbish. 

My Samsung TV is only a couple of years old, but only has arc, not e-arc. The TV can handle dolby digital plus from what I can see in the TV settings. I tested with a Dolby Atmos movie played via Plex (TV Plex app), and the Sonos app said atmos, so it does seem to be able to cope with it. I also tested a DTS-HD movie in Plex, and I got sound, but Sonos app said it was Dolby Digital 5.1, which is weird. 

​​​​Why can the Arc not handle DTS HD audio from my bluray player?

​​​​​​I tried a new hdmi cable to a brand new 2.1 version, same issues. 

Lastly, my Disney+ app will only show 5.1 audio as well. When playing Netflix Dolby movies, app says DD 5.1 plus. 

Any advice appreciated! 

 

 

It’s probably not the Arc that is the problem here. Most recent Samsung TV’s do not support (or pass through) DTS……

Note that Sonos HT will play DTS 5.1 audio, but they do not support DTS HQ or DTS-X .. the other thing that often causes issues, is that some TV’s may not pass-through the DTS 5.1 audio through its ports - I tend to check these things on rtings.com, but not every TV is listed on that website database.

If you post the TV model - I will happily see what I can discover from that website.

Thanks guys, my tv is Samsung QE55Q7FNA. 

This is what I was able to find (Samsung Q7FN/Q7/Q7F QLED)…

 

There are ways around your audio issues @Mikemacuk and that is to bypass your TV altogether with an audio extractor/switch - the three examples often referred to here in the Sonos community (in no particular order) are the HDFury Arcana or Vrroom, or the Feintech VAX04101A. So that’s something for you to perhaps consider.

OK looks like my TV is the issue. Thanks very much for your help. I'll look at the audio extractors you mention.... 

Yikes they are pricey! The Feintech looks good as it's a switch too. Does anyone in the UK supply it?

I ordered mine through Amazon in the Netherlands and got it delivered to the U.K.
