ARC and DTS

Yes, this setup should give you multichannel PCM 5.1 audio from DTS-encoded discs because the LG C1 is equipped with HDMI eARC. Just be sure to allow the Blu-ray player to convert DTS to PCM and allow your TV to pass through the audio through eARC to the Sonos Arc.

I still get 2.0 stereo……..connected to eArc I have changed the pass through on the tv and it goes silent. I watch lots of DTS movies on blu ray so perhaps I need to return my ARC for a Vizio Elevate.

What are the audio settings on the UHD player set to?

There are 3 options…….auto, PCM-Multi CH, and DTS-re-encode. I have tried all three and nothing changes……..do I need to change  I have read that the LG TV does not have DTS pass through and the Sonos Arc of course does not support DTS. So…...it appears I will be sadly returning the ARC for the Elevate. Someone suggested a HD Fury Arcana or an X box x….my god I do not game so what is the point to send hundreds of more dollars.

Try these settings:
 

UHD Settings

Digital Output - PCM

Sampling Frequency - 96 kHz

DRC - Off

HDMI Audio Setting - Auto

DTS Neo:6 - Off

TV Settings

Select HDMI Input Audio Format - Bitstream

Digital Sound Output - Auto

eARC Support - On

And be sure your TV has the latest firmware installed.

Thanks so much…..I will try this ASAP…..I am currently on the phone with Sonos to see if they have some resolution. I greatly appreciate all of your wonderful help. I will let you know. Thanks again.

Just  got off the phone with Sonos. They told me they could be of no help for my problem. Getting very irritated with Sonos. Anyway, I just changed the settings and still just stereo. I could not find the setting for the TV for Digital sound output…..just HDMI ARC device so left it there. All the others changed and still just stereo. Oh well…………..

What is your opinion of the Vizio Elevate?

Digital Sound Output should be under Advanced Settings:

Be sure the Arc is connected to the HDMI 2 port.

I would try each of these four combination of settings:
 

Select HDMI Input Audio Format (HDMI 2) - Bitstream

Digital Sound Output - Auto

eARC Support - On

Select HDMI Input Audio Format (HDMI 2) - Bitstream

Digital Sound Output - Pass Through

eARC Support - On

Select HDMI Input Audio Format (HDMI 2) - PCM

Digital Sound Output - Auto

eARC Support - On

Select HDMI Input Audio Format (HDMI 2) - PCM

Digital Sound Output - Pass Through

eARC Support - On

OK I will work on this today and tomorrow. FYI The ARC is connected to the HDMI 2 eARc port. Oh and just in case any of these work will I have to make this adjustment every time I view a DTS disc or will this be ok for Atmos discs too? Also, what about streaming with just the tv will I have to go back in and reset to prior settings? Thanks so much greatly appreciated.
