Sonos ARC and DTS Support

New cables are always good. Also make sure your TV settings for eARC are set to Auto Detect.

I have the tv squared away.  When the tv is set to auto detect i get awful sound.  

When I set tv audio to PASSTHROUGH I get better sound.  With the BluRaysettings as above I am seing only “Stereo PCM 2.0” on the SONOS, but that still is better than only front left and front right speaker.

I’m not in love with the DVD player.  I just picked it up Sunday.  I could swap it out.  It doesn't everything else so well, just this PCM / vs DTS audio out is choring me.  I’m replacing all with hi speed HDMI in a couple hours so i’ll see.  I used the old xbox HDMI cable for the new BRay but it’s still high speed, just a little older.  

Is your TV equipped with HDMI eARC? Is your TV up to date with the latest firmware?

When I set the Bluray to Digital Ouput to AUTO,  and the TV to PASSTHROUGH I get “DOLBY MULTICHANNEL LPCM 5.1” on the Sonos app but actually audio is only through the arc (2 channel) not the surrounds.  If I set Sony bluray to  Digital output PCM i get “Stereo 2.0” on the Sonos app and left and right audio from the surrounds.    TV is set to PASSTHROUGH so HDMI arc signal should be going direct into SONOS Arc.  When I set tv to AUTO i get stereo 2.0.  Passthrough i get the LPCM message above.  It seems to be a sonos software issue imo.

Thanks

yes tv hdmi earc, connected to net, latest firmware.  Again it works fantastic with an ATMOS bluray 4k DVD.  It’s just the SONOS and introducing this LPCM workaround.  If DTS were available we’d both have an hour plus back of our lives.

So strange. If you are getting Dolby Atmos from Atmos discs, then it isn’t a cable issue.

Its DTS and SONOS issue.  I mean for the all in pricing structure they have it’s not thinking too outside of the box to just license DTS and update.  I mean do you know how many posts and support chat boards there are on the subject?  it’s pretty lame.  the one thing that would cause a Cragislist sale of all SONOS and rebuild something else.  It’s that annoying.    I appreciate the info.  

Here’s one that’s similar to my situation:  https://www.reddit.com/r/sonos/comments/jsef3x/any_tcl_tv_owners_getting_lpcm_audio_with_the_arc/

Based on that reddit thread, it looks like it’s a TCL issue too. Most TVs equipped with eARC can pass through multichannel PCM but apparently the TCL currently isn’t able to.

Another option, besides purchasing a new TV or a different soundbar, is to get the HD Fury Arcana which will allow the audio from the Sony UHD player to bypass your TV and go directly to the Sonos Arc. I use the Arcana because my TV is really old. It works great with my Panasonic UHD player/Sonos Arc setup.
