Multichannel PCM on Arc

Are you really not supporting multichannel PCM on the newly announced Arc?

Why? It’s not a licensing issue this time.

It seems like there is always something missing with your home theater products.

Hi all,

We hear you. With a software update today, Arc now supports multi-channel LPCM, bringing new immersive sound experiences for gaming, Blu-ray discs, and more. To get support for multi-channel LPCM on Arc, download the latest Sonos S2 update from the app store and then update your system in the Sonos S2 app. After updating the app, go to Settings > System > System Updates > Check for Updates.

All the best,

Ditte

Wait… so I have a blu ray disc in the PS4 and it’s a 5.1 enabled movie. But with the update and changed tv settings, it’s still 2.0? Am I confusing myself?

Sounds like your settings are wrong and you probably do not have an earc tv?

I absolutely do have an eARC TV… so I’m unsure what I am doing wrong in the settings. I have it set to “auto” instead of PCM or passthrough and the PS4 is set to Bitstream Dolby.

You should set to passthrough.

I have a Samsung QLED. So the PS4 should be Dolby Bitstream and the TV passthrough?

Yes, assuming your TV supports Multichannel LPCM passthrough (should). Basically that way TV sends whatever it gets from PS4 directly to Arc. Arc should be able to deal with the audio now. Make sure your eARC is enabled.

Strange. I have a blu-ray in and it has a 5.1 DTS HD option and it’s still outputting Stereo PCM 2.0. eARC is enabled. On chat to Sonos now…

Sonos doesn’t support DTS. You want Multichannel LPCM or Dolby Digital 5.1 or anything like that.

Ahh. I’ll try a blu-ray with DD5.1… additionally, I’ve just put a game on and it’s just “dolby digital 5.1” and not LPCM unless I change the TV to “auto” instead of passthrough… sorry for the questions, I’m a noob!

You want the multichannel pcm output (can’t remember what it is) on the ps4, it doesn’t compress the audio and works now.

I’m having a nightmare here haha. I put in a new blu-ray that is DD5.1 and using passthrough or auto on my TV doesn’t work. I’ve also changed the ps4 to Linear PCM instead of dolby and nope… ahh!!

With these settings in place snd the firmware update, I would power off (completely- not just standby) the PS4, TV & Arc for 30 seconds then bring them back online (TV first) and let the devices do their ‘handshake’ again and see if that solves the issue.

Thanks for the reply. So, TV to passthrough and PS4 to dolby bitstream? Or PS4 to linear PCM?

I started a new question about my issue as to not clog up this answered thread… no idea why it won't output for me via PS4.

Sounds like lpcm is working great on the Nintendo switch, thanks Sono's - now just to find an ARC in stock as most of the time it’s sold out in the stores in my town.

Has anyone managed to test if it works using a PC - so running an hdmi cable from your pc into the TV and setting TV to pass through audio and then right click on audio settings in windows and hopefully the 5.1/7.1 audio options are selectable and not greyed out?

Thanks for answer. I do only get dolby digital 5.1 when using infuse, vlc, mrmc looking at mkv with dolby true Hd 7.1. Am I missing anything, thought this update would fix this. Happy for any help

Thanks for the update. It certainly has improved things. However, with my UHD 4k Blu-Ray Player (Panasonic UB 820), I have DTS set to PCM. It only still plays in Stereo PCM 2.0.

My Nvidia shield and Apple TV pays DTS titles with PCM 7.1 which is great, but very disappointed that the Blu-ray player does not. Any ideas?
