Sonos Arc LPCM

I own an Arc and a Sony UBP-X700 4K Blu Ray Player. I know how to set the Blu Ray player to output Bitstream so the Arc can decode Atmos, but what settings do I need to look for on the player and TV so the player will decode DTS and send LPCM through the TV to the Arc.

Thanks in advance for any help.

Try these settings:

Digital Audio Output: PCM
BD Secondary Audio: Off
DTS Neo:6: Off
Audio DRC: Off
Downmix: Surround

You may have to adjust your TV settings too. What specific TV do you have?

Try setting HDMI eARC and Digital Output Audio on your TV to Auto.

Please help. I changed all the settings as you suggested but when playing a blu ray with DTS the Arc under my system shows pcm 2.0 stereo. The interesting thing is, however, all the channels are working on the Arc and my One SL's are producing sound. How can this be?

Does the audio sound like you are getting 5.1 surround sound? Is the dialogue only coming out of the Arc and not the rear surrounds? Does it sound crisp and clear and enveloping like a Dolby TrueHD Blu-ray does?

Also, what other options do you have on your TV settings?

When playing DTS through the Arc by LPCM every speaker on the Arc is working and so is my sub and surrounds, but on the Sonos App it shows pcm 2.0 stereo coming into the Arc. I am confused how I'm getting multi channel surround but the app says pcm 2.0 stereo.

What speakers on the Arc would work if I was only getting pcm 2.0 stereo?

You can still get audio coming through the surround speakers with Stereo 2.0.

Do you hear dialog coming from the surrounds? If so, is it just as clear and loud as the dialogue coming out of the Arc?

If you truly believe you are getting 5.1 PCM audio playing from your speakers, it could just be that the Sonos app isn’t displaying the correct type of audio because of an issue between the Samsung and the Arc.
