Anyone else experiencing the same issue? Multichannel PCM 5.1 blanks out for a second every 1-2 minutes. I don’t think it’s a bandwidth issue as it works flawlessly with Multichannel PCM 7.1 (thorough test) and Dolby TrueHD Atmos (quick test). And it may have been caused by the Sonos 14.10 update. Setup is PS5→ LG C1→ Beam 2 (via earc).

 

2 weeks ago before the 14.10 update, I watched a bluray film wherein I had my PS5 transcode the DTS-HD MA 5.1 audio to Multichannel PCM 5.1 (as the C1 does not support DTS) and had no issues. Earlier today, I played a bluray film for the first time in 2 weeks and I encountered consistent audio dropouts every 1-2 minutes. It had the same setup where DTS-HD MA 5.1 → Multichannel PCM 5.1. I tested other bluray discs including the one I watched 2 weeks ago and they all now have the same issue.

 

Curiously, I’ve been gaming heavily on my PS5 the past two 2 weeks and haven’t had any audio issues. Then I realized that I’ve been using Multichannel PCM 7.1 when gaming on my PS5. So I made some changes under the PS5 sound settings to make it output Multichannel PCM 5.1 instead. Lo and behold, I am now getting the same consistent dropouts in games and even on the PS5 main menu.

 

I think it’s due to the Sonos 14.10 update as that’s the only firmware update I’ve done in the last 2 weeks. No PS5 update, no LG C1 update. Well actually while I was composing this post, I received and applied the latest LG C1 firmware update and I still have the same issue.

@thehowl  This issue appears to come and go seemingly at random. Maybe you’re just on a (very) lucky streak? Hard to believe someone somewhere fixed something else they’d have announced it by now.

Extremly lucky in that case. Still works flawless for me, I hope it never comes back. I will post here if it ever starts to cut out again.

PCM 5.1 still works fine after a week. Maybe it’s really been fixed? Appreciate if others can test and report back.

 

Edit: C1 and Beam running on latest firmwares. Haven’t power cyled yet though.

There was a new update for my LG TV 2 days ago and since then i have not had one drop out. I really hope this is the issue fiixed. 

It’s been a while and it’s still working so I think it’s really been fixed. Not sure if it was one of Sonos’ numerous updates or the latest LG update from months ago that fixed it. Just update your stuff to the latest and it’ll probably work.

I haven’t checked this thread for a while, so I thought I’d come and have a little look and see if there’s been any fix.

I was surprised to see that some people are reporting that this is no longer an issue. I’ve been running my PlayStation 5 and my set-top box on HDMI 3 and 4 but I have been using these with Dolby Atmos and stereo 2 channel respectively.
 

I have just gone and changed both to 5.1 audio and in initial tests it looks like this may be indeed fixed now. If so, that is awesome. I’m not sure what changed, Sonos or LG. 

I’ll report back if I get any issues or not.
