Still bad audio balancing for games with Arc Ultra, is it faulty?

A while ago I created this post: 


This is still a problem. For several games, if not all games, the volume is not how it should be. In the game Metaphor, dialoge form the sides are much louder than from the center. In other games, certain sounds seem too loud. These problems are especially bad when using Dolby Atmos on PS5, but also a problem in Linear PCM, in some cases just as bad like with the Metaphor example. I have tried several combinations without luck. This is not an issue with the TV or PS5 because this is not an issue with the TV audio. I am using passthrough on the TV and device type soundbar on PS5, but tested multiple combinations. Do I have a faulty Arc Ultra? I’m only using the Arc Ultra with my LG C4 TV, no sub or other speakers. I find it odd I can’t find anyone else reporting this.

 

Edit: I think the main problem is that the soundbar mixes up dialoge and music, so in Metaphor when characters are talking from the sides the volume is increased, but when it is from the center it is muted as if it was part of the background music since the channel for the music is also the center. I also explain this in a comment in my prevoius post, where I also tested turning the music off completely in game which did not fix it. The same seems to happen in dragonball fighterz. The dialoge of the commentator and in-fight voices are loud, but the winning speeches which is played with the winning music is lowered. Is this a bug that will be fixed or is my unit faulty? It’s annoying because the Arc Ultra is confused which sounds to increase and not.

If you shift the L/R balance does the center level increase? I’m not a gamer. Can you set the PS5 for simple stereo? If so, how is the center channel dialog?

No such thing for both of the things you said.


I came here to say that I’m also having problems with the Dolby Atmos setting on PS5. I’m actually finding LPCM to sound really good and balanced, meanwhile atmos is very much sounding off, like voices and waterfalls that should be surround coming from the front (generally the mix does not sound correct). I don’t have this issue with atmos supported games on PC. 
 

it seems like there’s issues with either the PS5 Dolby atmos setting or the Arc ultra with PS5 atmos.

I don’t think it’s the PS5 because when I use the TV audio from my LG C4 (which also supports Dolby Atmos), I don’t get any of the issues. Haven’t tested with another eARC soundbar, since I don’t have one, which would be an interesting test.

As I mentioned, I’m not a gamer. Also, I don’t have access to an LG TV. Technically, I think that some games are sending the L/R channels out of phase and the either the PS5 or LG is sending stereo audio out. Something in the chain is combining L/R in order to derive a center channel. The out of phase games, as a result of combining L/R, will partially cancel the center channel. I’m guessing that there is a configuration issue somewhere in the chain.

I did further testing and the only way I got the audio levels to not spike on the sides and be mixed properly was to disable eARC on the TV, but now it says Stereo PCM in the Sonos app, as opposed to multichannel PCM when eARC is switched on. If I pick Dolby Atmos on PS5 instead of LPCM then it says Dolby Digital 5.1 in the app (as opposed to Dolby Atmos when eARC is on), but this also has the same problem. I have to select LPCM on PS5 and toggle eARC off on the TV. However this sounds more flat compared to if eARC is turned on so it’s not a solution.
