Multichannel PCM 5.1 dropping out since 14.10 update

Seems like someone from The Verge is covering the popping sound issue. Sent them a PM and tagging them in case they’re intested to look into this as well @tomwarren 

Another small bit of information from testing with 4k blu rays being played on PS5. (LG C3 and Sonos Beam 2 w/ 2 era 100s
-Dunkirk 4k UHD had audio dropouts (5.1 soundtrack with ps5 set to 7.1 on HDMI port 3)
     -I had hoped that the 7.1 sound setting would have covered this since it works fine for video games.
     -After switching to HDMI slot 1, the issue resolved.
-Mission Impossible: Fallout (Dolby Atmos HDMI port 3) worked flawlessly without any tweaks necessary.

I haven’t had any issues with dropouts when it comes to streaming from the TV directly. That includes 5.1, and dolby atmos. Hopefully at some point, Sony will push out dolby atmos support natively to PS5, maybe with the rumored console revision.
 

Hi All, 

Don’t know if it’s helpful or not or just more of the same. I too am having this issue. I have an LG C2 48”, a Beam gen 2 and two ERA 100s as surrounds. 

The rest of my kit is an Apple TV 4k and a Nintendo Switch. All bought last week. All was good until I learned that the switch had 5.1 surround and started with the cutting out of sound every one or two minutes. 

My switch was plugged into HDMI 3 and the ATV was plugged into HDMI 1. When I switched them I had the opposite problem. Switch was fine in HDMI one, but ATV was cutting out when watching DUNE on Netflix. 

Sorry I don’t understand the difference between Atmos, DD, PCM, pass through etc., so I haven’t been able to properly troubleshoot. But seems like another data point to add to the list so I thought I’d post anyway. 

Incidentally, also embarrassing with my already skeptical spouse, when I can’t even easily set up a movie to watch on the new kit without having to muck around with settings and cables. 🤷‍♂️

Thanks all for working on it. I may try the cable fix posted earlier. But what do I lose if I just move the Sonos Beam to HDMI 3 or 4 and lose the eArc. Does that just mean I can’t talk to my TV?

Thnaks! 

If you were to download the apple tv app on the TV itself and watch dune that way, you wouldn’t have the audio dropouts. Or if you cast it from your phone. 

Thanks, I did think of this but I was hoping to use the ATV for everything rather than the WEB OS on the LG for anything. I do take your point though so thank you. 

The audio return is on HDMI 2 only. You can’t connect it to any other port. The optical cable should fix the issues for you though. 

Okay, thanks. I just ordered this one from Amazon:

FIBBR 8K HDMI Fiber Optic Cable, FIBBR 48Gbps Ultra High Speed Gaming HDMI 2.1 Cable 8K60Hz 4K120Hz 144Hz Dynamic HDR/eARC Active Optical HDMI Cable Compatible with PS5, Xbox Series X, PC, TV(6.56ft)

Had to order from a vendor in China. I couldn’t find any options in Canada/USA that were in stock.

Had the same issue with audio occasionally dropping for a second every few minutes in av amplifier 5.1 setting from ps5.

Setup: ps5 + sonos beam 2 with 2 sonos one surrounds+ lg c2.

Sound input from ps5 - bitstream (for surround)

eARC enabled

Sound output - passthrou 

Quick fix worked for me: switch hdmi port for your ps5 to an previously unused one (or hard reset current one). Do not set your ps5 hdmi input type to PC. Check if audio don't drop in av amplifier 5.1 and that your sonos system get 5.1 PCM.

I suspect doing PC input type for ps5 hdmi port is the case, cause it's literally the only difference between working and problematic setup.

Can also confirm that this “fix” worked. Thanks!

LG C2 + Beam Gen 2 + PS5 (watching Blu-ray)

Audio dropping 2-3 seconds every few mins whilst watching multichannel PCM 5.1. Sometimes audio comes back funny, like a vocal track missing. Restarting the Blu-ray brings it back. 

I tried moving the PS5 from HDMI port 3 to port 1. So far so good, but only 30 mins into a movie.

Will update..
