How far is the left Era 300 from the side wall? How far is the right Era 300 from the other side wall?

There are shelves on either side.  These are wall mounted on my back wall and my head is on my bed, a foot lower than the speakers, and they are roughly 7 feet apart.  Equidistant in all directions.

And didn’t I mention MANY times that I did not have this issue AT ALL WITH MY ARC?  It was only until I pulled out the Arc and put the Arc Ultra in its place on the app version prior to 80.14.07 (which is 80.12.03) which did a system update and it worked fine.  But when I upgraded to 80.14.07 and did the system hardware update within the app (and which I check for new versions of, daily), it completely messed everything up, HORRIBLY!  So bad in fact it was ACTUALLY WORSE THAN ANYTHING I EXPERIENCED ON DAY ONE OF THE NEW APP DESIGN WITH MY SAME EXACT SYSTEM WITH THE ONLY DIFFERENCE BEING I WAS USING THE ORIGINAL ARC INSTEAD OF THE ARC “ULTRA”.  Another note of mention, when TruePlay is turned off, you can hear the full musicality of the Arc Ultra and nice stereo separation.  But after running TruePlay on it either with QuickTune or Advanced Tuning (which I’ve done on the system at least 50 times now of each way, AND THE SOUNDS IT PLAYS DURING THE TUNING ARE PERFECTLY BALANCED IN VOLUME ON THE LEFT AND RIGHT ERA 300 SURROUND SPEAKERS), the musicality is about ¼ of what it is when TruePlay is turned off, and even trying to compensate for it with EQ adjustments and speech enhancement levels, which I find best on high.  After TruePlay tuning I find it much more bass-present in the center channel which is great for dialogue but not for music, and a noticeable drop in treble on left and right soundbar channels, even when I increase the treble.  (It also increases the midrange and mid-bass in the rear channels and makes the rear volume louder than the front by a wide margin!)

CAN THEY NOT SIMPLY REVERT TO THE APP VERSION BEFORE 80.14.07, (WHICH IS 80.12.03) AND ALLOW ME TO REINSTALL THAT APP WITH IT’S PARTICULAR SYSTEM HARDWARE UPDATE?!?!?  That should, in theory, fix these problems!!  (I would hope…)

And putting the Arc back as a temporary fix wouldn’t work now, as the two Era 300s and the two Sub (Gen 3)s all have the most recent system hardware update.  So even if I didn’t system update the Arc, the other speakers would still act the same, as well as the horribly updated and damaged TruePlay software – and of course the Arc Ultra and overall horribly poor and DESTRUCTIVE system updates, because as I mentioned earlier, when I change channels on my Xfinity XG1v4 (4K) DVR cable box made by Arris (which is one of the best cable boxes in the industry and which worked perfectly fine with THE ARC, of course it was before the system hardware update in app 80.14.07 and worked fine with app 80.12.03 and its system update) or start/stop watching a recording on my DVR box, the entire system MAKES A DISTORTION THAT SOUNDS LIKE A VERY LOUD (5x as loud as the volume is set to) TEARING OF PAPER THAT I KNOW WILL DAMAGE THE DRIVERS EVENTUALLY!! 

CAN I PLEASE GET A REPRESENTATIVE FROM SONOS TO REPLY TO MY QUESTION (and read this reply as well)?!?!?  I WOULD REALLY APPRECIATE IT BECAUSE I LIKE THE SPEAKER BUT NOT WHAT YOU DID TO THE SYSTEM UPDATES AND THE TRUEPLAY UPDATES!!

•  Otherwise, I’ll have no choice but to sadly return the $1000 Arc Ultra for a full refund with you paying for shipping, too, and I’ll also have to start posting about this on my audio forums as well as no longer being able to recommend SONOS speakers – at least until such point as you stop fixing problems and then damaging them again.  You should be testing this on your BEST, MAXED OUT system like I have (but I’m sure you’ll use the Sub 4s, which don’t sound any different, but I’d prefer you try it with two Sub Gen 3s like I have).  I have over $4,400 invested in SONOS and another $950 to a professional home theater installer (and his assistant).  So please fix this very serious problem immediately!

Thank you very much.  

Hi ​@Bellatone 

Thanks for your post!

Sorry to hear of these issues you are having with your Arc Ultra, and the surround speakers connected to it.

I recommend that you remove the surround speakers from the Arc Ultra in the app, then add them back on again: Settings icon » nRoom with Arc Ultra] » Remove Surrounds. Please also remove the Sub(s) at the same time with the Remove Sub option.

Please then bond the Sub(s) and surrounds back on to the Arc Ultra with the Connect Sub and Set up Surrounds options in the same section of the app.

If this does not clear the issue(s), I recommend you get in touch with our technical support team who have tools at their disposal that will allow them to give you advice specific to your Sonos system and what it reports.

I hope this helps.

Thank you, Corry.

Which should I remove first (subs or surrounds) and re-add first (subs or surrounds)?

I assume I will need to redo the TruePlay advanced?

Please advise.

Thx.

Hi ​@Bellatone 

It should not make a difference, but there is anecdotal evidence suggesting that things go better if you add the Sub after adding the surrounds. I don't think it'll make any difference which order you remove them in.

If any change is made, TruePlay Tuning will be lost, yes.

I hope this helps.

Thank you.  How about the order of removing them?

oh, and an interesting thing happened last night.  I’m using 8K HDMI hologram certified 1/2” diameter cables on all 4 inputs including the eARC for my Arc Ultra (and worked perfectly fine with the Arc) but I woke up last night (half asleep) to about 2 hours of staticky sound in my Arc Ultra until I unplugged the HDMI and plugged it back in to the Ultra end.

im beginning to wonder if the Arc Ultra is defective.

Hi ​@Bellatone 

This is strange. If this happens again, please submit a support diagnostic while the staticky sound can still be heard, then do what you can to fix it. Then, at your convenience, please get in touch with our technical support team who have tools at their disposal that will allow them to give you advice specific to your Sonos system and what it reports, and give them the number of the diagnostic you submitted. Hopefully, it was a one-off.

I hope this helps.

It’s not a one off.  When I change TV channels or start/Stop a DVR recording, 1 out of 2-3 times, it makes a very loud, distorted tearing paper-like sound on all speakers that is about 7x louder than the volume I’m listening at, and I know from audio experience that it will eventually destroy the drivers in the speakers.

(I also build high-end audio cables and power cords under the name Bellatone, and built my own $80,000 balanced headphone amplifier and linear regulated power supply based on the AMB Labs Beta22 and Sigma22 plus tons of customization like extra PCBs that I designed and a remote control system for a stepped attenuator, only 0.01 ohm output impedance, dual chassis, 105 lb. total, and I graphically designed the front and rear panels as well as the CAD work, and all text/graphics are laser bleached at 600dpi instead of crappy silk screening;  I have a $140K headphone system and nearly $40K in high end headphones.)

Corry,

You’re a genius!  I don’t know about the tearing sound yet, if it will do it again, but I fixed the surround issue!  However, I made sure to UNPLUG ALL OF THE SPEAKERS FIRST, INCLUDING THE ARC ULTRA (and I unplugged the Arc Ultra before ALL the others), after I first removed the subs and then removed the surrounds.  When I added back the surrounds, I fortunately picked the room it assigned to my right surround (as the previous times when it asked me where the sound was coming from it was always the left one), but this time the tone came out of my right surround.  Then I added the subs and didn’t have to do the NFC thing again since it only flashed white on all speakers and not green/white, so it obviously held them in memory.

Then I did the advanced TruePlay and the SURROUNDS ARE BALANCED!!!!   I’m so happy!!!

Thanks so much, Corry!  (Btw, are you a M or F?, just curious due to the spelling of your name.  And how old are you, if you feel like answering? I’m 45, but people always think I’m anywhere from 27 to 35.)  You really helped me out a lot, and I’m keeping this thread UNANSWERED for the moment to make sure A) the distortion tearing sound is gone, and B) so you get a chance to view some of my headphone equipment.

Eventually if there is no more distortion (as there was none with my Arc), I will mark your post that gave me the instructions as answered!
