Hi - other SONOS ARC owners have posted this issue previously but it did not reach a resolution so I am reposting.  

I’ve just purchased a Sonos ARC and I’m having to constantly adjust the volume level up and down to compensate for the extremely low levels for dialogue vs action / music.  The dialogue levels are extremely low in any movie compared to action and music.  

I am using the ARC with a Samsung 55 inch 2019 model.

I have set night mode and speech enhancement on.  Still getting the same issue.  

There appears to be no further adjustment / modes in the SONOS app to adjust dialogue to music / action balance other than reducing SubWoofer level.  

DEAR SONOS team - surely this is a software setup issue which is resolvable?  Please let me know - really don’t want to send it back!! 

Quite bummed!  Love my Sub, Play 5 Gen 2 and Gen 1 and Play 3.  

Thanks in advance for your timely solution to this issue.

Hi all - for what it’s worth… I had a brand new Arc about a week ago… music and effects sounded excellent in stereo, 5.1 or Atmos. Dialogue was generally “fine” in stereo… but as soon as I tried 5.1 or Atmos it was a muddy, mumbly, tinny mess. Certainly nowhere near the sound I paid that sort of price for. 

 

I spent 90 minutes on a call to Sonos support and tried every setting and little bit of trouble shooting going - I didn’t get anywhere.

 

I returned the Arc for a Beam Gen 2 and the difference was night and day - dialogue in 5.1 and Atmos was now clear and crisp. 
 

So, for anyone not getting what they want from the Arc, I highly recommend trying a Beam! Sometimes more expensive doesn’t equal a better experience. 

I have a beam gen 2. Sure its clear and crisp. But it is too clear and crisp. It sounds like it comes from a tiny phone speaker on max volume with no depth what so ever. Looked at lord of the rings the other day and action scenes sounds amazing but the dialogue sounds as if the cast is totaly out of place speaking to me in a phone with no bass reflecting the environment. Clear and crisp is good, but it is not all you need in good speech representation. It needs to be adjusted to match the environment. Heck the cast dont even sound like them selves. They sound like, as i have mentioned here and there like they talk on the phone or somehting bass less..

I’ve been plagued with the same problem for months now. It all began when I plugged my laptop into my living room TV (LG webOS NANO90UNA) for a webinar. I must’ve toggled a setting that caused the dialogue to sound as everyone has described: muffled, underwater, etc. Today I decided I was going to figure this out. Nothing on the app helped. On the TV itself I went to Settings>Sound>Additional Settings>Digital Sound Out, which was set to <Auto>. When I switched it to PCM, boom. Problem fixed! Perfect. 

I can’t speak for any other brand, obviously, but this fixed my issue. Good luck!

When you switch to PCM you lose the ability to listen to 5.1 audio.

To echo everyone else, I am having the exact same issues. Extremely disappointing.
On top of that I also have audio delay.

I have the Arc, Sub (Gen 3), 2xOne. On an LG CX tv.

I have the Sonos arc and am extremely disappointed in the dialogue lack of clarity on streaming channels .  I have adjusted settings on the iPhone app and run trueplay many times . I have also adjusted the sound settings on my roku device . All to no avail .  For a $900 soundbar to perform so poorly in this regard is frustrating . I have a Samsung 2019 Oled tv  Any suggestions on a fix would be a Christmas miracle at this point  . Let me know if there are any

Did you call Sonos?

I reached out to support and have received the generic turn on the dialogue / adjust EQ settings responses .  What does live support do ? 

I noticed my sound issues were most notable with streaming services. Your tv settings may be causing the issues with the center channel sound volume. On my LG C1, selecting "pass through" under digital sound output in the advanced sound settings has made a HUGE difference. I think any other settings are double processing the audio resulting in the muffled voice. Not sure for other tvs, but I'm guessing any settings other than pass through are causing the issue. Even "auto" settings seem to still negatively process the voice audio. At least with LG...

I've also done some comparative testing. For me, native apps in the tv produce better sound than the native apps in my Xfinity cable box. Disney+ plays in Atmos with the LG app and 5.1 with the Xfinity app. Atmos processing seemed to be most improved selecting pass through as well. Not sure about a Roku or Firestick as I only have old ones of those.

Also in advanced settings, make sure the HDMI iaudio format for each input is set for bitstream. You may have to do some testing to get it to work. My Switch needs to be set on PCM to get audio to work with pass through settings. Not sure about PS5 or Xbox since I don't have those.

Good luck!

With so many complaining about the crap dialogue and piss poor replies back from Sonos basically trying to say there’s nothing wrong it’s everyone’s set up problems, it’s clear to see they do not give a *.

so disappointed 

there was a stage at some point where this was not a problem and the sound was brilliant but then it all went to * and they can’t admit it😓

*Moderator Note: Modified in accordance with the Community Code of Conduct.*

Any Sonos Bar set up is a compromise for convenience over a AVR based HT wired speaker set up with a dedicated centre channel/speaker and this is one of the prices paid for the compromise.

One workable solution is to use subtitles for dialogue. It does not take long to get used to it.

Turn on subtitles, because our $900 soundbar isn’t capable of producing dialogue that can be heard consistently?   You can’t be serious.

Yes. still have dialogue problems, never bee fixed, just ignored by Sonos. Still the amount of times I have to turn up the volume to hear the dialogue and then turn volume down when action etc kicks in. Need some sort of centre channel control.

Came here to say I’m also experiencing the same faults. Had this unit since it’s release, but now I’ve been at home on holiday and watching more movies, it’s become quite apparent that there’s a serious problem with voice dialogue and yeah, I’ve tried most of the processes to improve audio.

 

Was watching Dogma yesterday and was just annoyed having to up and down the volume on the TV, as we’re in an apartment and have young kids which don’t need waking up!

 

This thread has been here for years with the same faults, yet Sonos has done diddly squat to respond, let alone fix.

Have you provided them with hard data, via a diagnostic, and called them so that they will look at it?

I, too, get frustrated, but it’s always with the audio mixer for the original source, and not Sonos, as I can duplicate the issue on non-Sonos setups.

Why should I have to do their job for them? It's not hard to replicate. 

 

So many people are having the exact same issue to the point they could easily say "you might need to check that your TV or media player settings allow this or this feature to help clear up voice" 

 

Seeing that it's literally only the Arc having the problem, it seems pretty clear where the focus needs to be, including better customer service, regardless whether it's a forum or not.

I really see this as a Sonos problem. Yes the bad audio levels aren’t Sonos’ fault, but with an AVR system you can easily boost the center channel to correct for bad content.

No idea if the center level is adjustable on other sound bars or not but if it is that is a selling feature for them when compared to Sonos.

 

 

Unless it’s something that they have not been able to replicate? I don’t know, I don’t work for Sonos, but if I’m going to complain about an issue, I’m going to try to be part of the effort to fix it, rather than waiting for someone else to maybe figure it out. It’s affecting me, I’m the one who should be helping figure it out, especially if, by some odd chance that it’s an issue with my personal setup. I’ve always assumed bugs get prioritized by how much data is available. That’s certainly one of the key components we looked at when I was managing a software group. A lot better chance of figuring out what the cause was, with multiple data points to look at and compare. Nothing worse than tasking a programmer to look at an anecdotal bug, with no data to support the investigation.

Just complaining isn’t my style. 

I was on the point of contacting Sonos before reading this thread, as I have been experiencing the exact same problem with my setup, being the Arc paired with the Sub Mini. Listening to music is fine, but it’s as though there is no mid-range on the Arc… Dialogue is scratchy / squeaky and on modern films, like Oppenheimer, I gave up halfway through as 50% of the dialogue is totally inaudible. I’ve tried changing the TV set up, splashing out on a very expensive HDMI cable… and continually adjusting the EQ…. I have now given up… so will be listing the Arc on E-bay

I see this is your first post here, but before I even consider bidding on your device, how do you know it’s perhaps not a defective product, or even if your TV output is the issue? 

On my LG C1, selecting "pass through" under digital sound output in the advanced sound settings has made a HUGE difference.

This worked for me. I have a Beam Gen 1, Sub Gen 1 with pair of One SLs connected to an LG NANO91 and an Arc, Sub Gen 3 with pair of Era 300’s connected to an LG C3 - both use Apple TVs as source of content.

The Beam sounded consistently deeper and more pronounced than the Arc.

I’ve tested with and without Trueplay, tweaked heaps of settings, but today tried the above while watching Top Gun Maverick and it was a huge improvement.

The Era 300’s are amazing but they were constantly drowning out the Arc. Now the sound is significantly more balanced and the Arc finally draws your attention forward.

For me at least, this doesn't sound like a ‘Sonos issue’.

I believe I have fixed the dialogue problem on my Arc. Just got my system over the weekend.

I tried a posted fix above but couldn’t because I don’t have that particular sound adjustment. So in my settings under the sound settings, I selected reset sound. I of course had to adjust the default tv speaker selection to receiver…but now I can hear and understand the dialogue! 
 

I'm going to check out more types of programming to make sure but this is great. Perhaps I won’t return my Sonos system after all.
