ARC outputting Stereo PCM when playing 4K Blu Ray

Hi all,

I recently upgraded my Beam Gen 2 to an Arc and ever since I’m only getting Stereo PCM outputted when I play a 4K Blu Ray that outputs DTS HD. This was working fine on my Beam 2 and it would convert this to PCM Multichannel 7.1.

My set up:

TV - LG C1 - Passthrough and eArc enabled 

Sound - Arc, Sub Gen 3, Era 100’s x2

4K Player - Panasonic DP-UB450EB-K

 

Dolby Atmos works fine but since changing to an Arc it’s only converting DTS HD to stereo PCM.

I’ve looked through all the posts on here and it seems a lot of people have had this problem before. I’ve amended my settings on the Blu Ray player but this hasn’t worked.

Any help would be greatly appreciated.

Thank you

Hi. Yep i’m having the same issue. Started about 4 weeks ago. DTS-HD 5.1 discs that I’ve previously played with no issue are now playing with no sound. 

When changing the sound on my LG C2 to PCM it works, but only showing ‘Stereo PCM’ on my Sonos app.

I’ve updated everything and unplugged multiple times - something has definitely changed!

 

However….i decided to watch The Dark Knight the other night and despite it showing as Stereo PCM on my Sonos app, it sounded great. Tapped the Display button on my Sony UBP-X700 remote, low and behold it’s showing as 5.1 sound! 

So whilst i’m not 100% sure what i’m getting, this could just a problem with the Sonos app displaying the wrong information (Stereo PCM). Either way it sounded great so for those having this problem, might be worth you checking this on your 4K players 👍🏽
