When did this update that you speak of come out? I have auto updates on (though it doesn't seem to stay on top of them) and my system is fine. Granted, I have all first gen Sonos products. Perhaps it was only for newer gens?
There were several updates that hosed things. 14.6 caused many people, myself included, to have surrounds and subs to drop out frequently, requiring a system reboot, only to have it happen again (primarily when switching inputs, but not always - in my case I never switched inputs and it still happened).
14.10 addressed most of those issues, but also introduced a lower level voluming issue. For some peeps, they have to really crank it just to hear the subs. I bit the bullet and finally updated and while voice quality is improved (new feature - I can tell a slight difference), audio levels are a bit down and I have to jack it up a little more than before.
That being said, I have an Arc, two Ones as surrounds and two Gen 2 subs (or whatever the latest are - I forget).
Sonos is not a high-end out of low-end surround systems (like someone else mentioned). With the exception of a few firmware updates that took a little too long to get resolved, my system rocks. I consider it high-end surround system.
Yes, I know it's a "soundbar" system and not a true 5.1, 7.1 whatever, but in my little living room it kicks butt and when I open the front door, sit on the porch with music playing, it can shake things and wake neighbors. Atmos movies sound great.
Sonos needs to be little more transparent with firmware issues - 14.6 took months to resolve and Sonos support lvl 1 techs said it was a "network issue - something is wrong with your wifi" which was total crap. Enough people complained (myself included) and they finally figured it out and addressed it.
My advice, turn off auto updates (I did) if you own a Sonos anything and check the Sonos forums for info about any updates. If it ain't broke...
And, if they do release a mini sub, I just might bite - can't have too many subwoofers IMHO. Then again, I have tinnitus and hearing loss (not that bad - I was also a musician so I have an ear(s) - just not as good as when I was 20) so what do I know
