Sonos Arc Muddy/Bottoming out Bass

There are multiple layers to the software. Some layers are installed at the factory and are not part of a user update. What if there are multiple production stations and one of them installed a defective software layer?

I don’t think that we yet know if this is a hardware or software issue and what percentage of the shipped units exhibit the issue.

Even at light speed it will require a few days to get a unit back to the lab and start researching the root cause. Due to COVID-19 concerns, the lab is probably not working with a full staff. If an engineer needs to travel to the production facility, there could be delays.

I am aware of another manufacturer’s product where a model had a nearly 100% failure rate during or just after the warranty period. The manufacturer took care of its customers and most were pleased and willing to purchase more of the manufacturer’s product. This is certainly an embarrassment for SONOS, but it does not need to be terminal.

Patience is required.

So I've been following this thread since the begining and was afraid this would include mine. Just got it and tested it out with previous examples as mentioned here. Mine does not have the issue. True play was on and loudness. Did not hear any issue with the bass. So I guess it's a batch problem?

Went from beam to this one and I have to agree that it requires higher % to have the same volume as beam

Mine was delivered and bought in Norway. Arrived today to the shop from Danmark. 

I don’t have it all the time.

Oh.. So I guess I have to test it a little more then. Anyone got good song examples? Or movies with what time in the movie? 

I tried a hardstyle song and them it happend to me. JeBroer - Engeltje is the song.  (Dutch)

not my normal cup of tea

• What are you watching or playing that you’re hearing this on? Be as specific as possible please and let us know if it’s only with music. For music, it helps us build a list of tracks and sources that we can recreate the issue with. jeBroer - Engeltje

• What volume do you experience this at? Does it only show up after a certain percentage or do you notice it most of the time? Noticed it with higher volume > 50%

• Is your Arc wall-mounted? No in front of tv

• If wall-mounted, does removing the speaker from the wall bracket and setting it on a credenza or table improve the issue

• Are you using Trueplay, and does it go away if you turn Trueplay off? Using trueplay. Not tested without yet

• Do you have the Bass EQ setting flat or adjusted in some way? +3

• If it’s possible, can you share an image of the setup? 

• Please submit a diagnostic from the system with it happening and let us know the number 1100352809

Also the toy story 3 one someone else I know with one seemed to think he initially had it in stereo it wasn’t as evident as when he switched to 5.1 so make sure it’s at 5.1 or atmos at 50-70%
