Ever since upgrading Arc to Arc Ultra, my left Era 300 is 10x louder than the right one!! (If not resolved before my return date I will return the ARC ULTRA!)
I always upgrade to the newest app the day it comes out but I already had the current one at that time which was the one before 80.17.09 and 80.17.07, and it did a system update to my new Arc Ultra. The rear speaker balance sounded fine after I ran a full TruePlay on my system with two Era 300 rears and two Sub (Gen 3)s.
(But why with the Arc Ultra is the option not allowed, greyed out, to adjust distance between surrounds which I never had different before anyway but previously I had it on 2ft to 10ft, and now it is greyed out on more than 10ft, or not allowed to change the phase of my subs, which should be independent by the way — as should volume, balance, bass, treble, and height controls be SEPARATE for Arc Ultra/Subs and SEPARATE for the Era 300 surrounds?)
But once I did the system update to my hardware in 80.17.07 came the problem of the left era 300 being 10x louder than the right era 300 surround speaker!!!! This is worse with TV Video than with music, as with music the left rear is only 4x louder than the right which is still horrible! AND THIS MAKES NO DIFFERENCE IF TRUEPLAY IS TURNED ON OR OFF (but I’m glad you restored the option to turn it off and a separate option to retune like it used to be with the Arc, BEFORE YOU CHANGED TO THE NEW STYLE APP LIKE 10 MONTHS AGO OR WHENEVER IT WAS)!
I have begging for this to be fixed along with another problem THAT DID NOT EXIST WITH THE ARC! I had zero issues with the Arc in my system, and the Arc had a wider soundstage due to its midwoofers and a fuller but not taller height. The stereo speaker sound is obviously better with the Arc Ultra, but I now have to turn my bass up higher than before for better dialogue.
The other problem is that now when I change TV channels or stop/start a DVR program recorded in my Xfinity XG1v4 4K cable box, it makes a distortion sound like tearing paper at 20x the actual volume level which will eventually destroy the drivers and it does this in all the speakers!!!! This never happened once with the Arc!!! The ONLY CHANGE WAS PUTTING THE ARC ULTRA IN PLACE OF THE ARC!!! And also when I need to switch certain settings on my TV for other reasons than sound, my screen will go black for 5 seconds before it comes back on and again THIS NEVER HAPPENED WITH THE ARC AND THE SAME OTHER SPEAKERS IN THE SYSTEM!!! Oh, and now 3 TV channels are much lower volume than the rest, and I notice in the app that it tells you if it’s Dolby multichannel 2.0, 5.1, DD+, or Dolby Atmos.
On my AppleTV, it only seems to be playing Dolby Atmos from the AppleTV+ area, and none of my movie apps that are broadcast in Dolby Atmos!! This never happened once with the Arc, and there is a very audible difference and you can easily hear when Atmos is on, without needing to read it under TV Source window in the Sonos app.
There are other issues as well but these are the most pressing ones. For example, now I need to turn my volume higher on my TV channels than with the Arc and much lower than on YouTube app built into my TV which formerly the volume was at 12-14 (as the volume only moves in levels of two numbers at a time; you can choose 1-99 or 2-100, but only 50 options with TV remote).
THESE NEEDS TO BE FIXED IMMEDIATELY OR I WILL BE RETURNING MY ARC ULTRA BACK FOR A REFUND!!!
