Low Volume- Sonos Arc

To me this looks like a cross product fault on the products, the fact that on TV normal view the sound peaks at 80db at 100% but on spotify app from the same tv at 50% I get 92db, that’s a huge difference.

Clearly the speakers themselves are capable but I suspect there is a software bug effecting all sonos products. When you read text from Reddit and this site people mention several brands of TV on both the beam and the arc. 
 

Until the community shout loudly enough there won’t be a fix, instead I imagine internally they are blaming TV manufacturers etc. Which I see a lot in electric cars - charger company blames the car while the one blame the charger. result is very little action until buybacks are used. then suddenly they work together to find both are partially at fault.

That is the sad truth of for profit companies they are hear to make money. that said I like sonos products the build quality is nice, I like the idea of building up a system over time, sound quality is good to my ears - it’s just this issue that’s ruined the experience, it feels like the systems been kneecapped because of it.

I can see there's a problem here. To me it seems you're a bit quick in pointing at the speakers, especially when your conclusion is that there's “a software bug effecting all sonos products". Only some people's systems seem to be affected and since Sonos is depending partly on your TV, there's another possible cause here.

My Beam and Samsung QE65Q90 are not affected.

maybe, but faults are really 100% hit rates, even major recalls 75% of people wont have experienced the issue. yeah it could be an issue with the TV but then again LG are just as likely to say that’s it’s not an issue with their TV because it works with other bars etc. Probably like the electric car issue - both parties have a part to play.

Only sonos knows but their customer service has no been helpful atm, I’ve got another call with them today to try an progress the issue but I’m quickly coming up to the end of the return period - ideally i like to keep the system so hoping that eventually they say something like they know what the issue is an working on a fix which I would happily take but atm it’s is night mode turned on, turn it on and off etc, send us a session number etc.  That’s why I’m frustrated.

I had a similar issue. Muted audio and unclear voice in songs on youtube music. . Airplaying the same song directly to Sonos played the expected clear and loud levels. So the issue was not in Sonos.

Setup was Roku Ultra → via HDMI → Samsung QN85DA → via HDMI eARC → Sonos ARC .

Solution:

1. Go to Roku → Audio → - Digital output Stream to “Passthrough” 
2. Go to Samsung or your TV and set digital Audio output to “Passthrough” as well

It’s not an Arc problem. The sources upstream are applying their logic/codecs to pass modified audio downstream. Let Arc do all the handling. 

Went to the local lab today and they told me that after checking with manufacturer setting - all is ok with the ARC. 
I told them I am playing music at 80-90% of the volume at my living room and they didn’t know what to tell me… 

I have the same problem. I do not expect Sonia customer service to respond. Since going public CS is poor!

I agree. I just purchased the arc to replace my playbar. Don’t know why I spent the money, it sounds no better than my playbar!

Hi,

I have the same issue with my New arc, works fine since 2 weeks and now volume are very low in netflix or myCANAL and high in YouTube for example.

applications are in my Apple TV 4K.

the only things who change is my Arcana HD fury who receive the HDMI for the sound, I don’t use my Sony TV who have not eArc.

i can’t activate the pathrough mode.

I spoke with a Sonos rep and we discovered Comcast’s cable audio output (via “Settings” ) was set to PCM, not “auto”. I changed it to Auto and saw significant improvements for cable. I’m now able to hear at 25, not 50. I later played with some Samsung native apps like Netflix and saw improvement there by switching the audio on a show itself from “English Original” to “English Original 5.1”

Same issue here...sonos customer service was pretty good with looking at 4 diagnostics from my system...they didn’t see any faults on the diagnostics and one CS rep told me that this is unheard of and said it was a defective unit...so i get another ARC….no change….the technician said it probably has something to do with software up stream and has seen this issue with some other customers….thanks everyone in this forum as I have tried many different options here….I will keep an eye on this as I think Sonos should have fix here!!
