Sonos AMP subwoofer level adjustment appcrash

@fforssell: How do I downgrade my Android Sonos app?

@MG-Craft , have you provided a diagnostic for Sonos to look at, and told them the number to look at? Most engineers I work with want hard data to look at when hunting bugs, and not just anecdotal evidence. I don’t doubt your conclusions, just think that providing a diagnostic after a crash would give them a lot more data to look at. Especially if they’re having difficulty reproducing the issue locally, your logs might help them understand much more quickly. 

A quick google search will tell you that “Open the app that you wish to downgrade. Tap on “Uninstall.” This will remove the current version of the app from your device. Tap on “Security” and check the box next to “Unknown Sources.” This will ensure that your system accepts third-party apps. Head over to ApkMirror and download the desired version of the app.”.  Furthermore, you need to disable auto-update for the app in Play Store, otherwise you will end up with the current version reasonably quickly.

This is probably something Sonos absolutely dicourages you from doing.  Me nor anyone else will take no responsibility for the results or the security of said procedure, so proceed fully at your own risk.

@fforssell: Thanks!

@Airgetlam: I have the logs but have not yet opened a trouble ticket with Sonos. Will do now… Thanks!

@Airgetlam The support chat already told me that the issue was known, without asking for a diagnostic number, and I didn’t insist on providing one.  Should I doubt their answer?

That’s up to you. I’m a big believer in ‘more hard data is better’, along with the obverse ‘there sometimes is more than one issue that can cause a symptom’, so to me, providing them the opportunity to either say ‘yep’ or ‘huh, that’s different’ is important. 

I have worked with a bunch of interesting and extremely talented engineers over the last several decades. Giving them hard data has always been better than any other approach. And sometimes, the issue hasn’t been what was assumed, but something completely different, either unique to my setup, or issues with the way I was doing something, etc. which wouldn’t show up in the ‘telling’ part, just in the logs. 

He guys… quick update.

With my Sonos desktop app, I just completed an uninstall, reinstall, and update cycle and - much to my happy surprise - I discovered that the app was updated and the problem was fixed… at least on my Windows PC.

Last night:

This morning: 

Will turn back to the Android app issue later… back to work for now.

Thanks for your input along the way.

[SOLVED FOR MY CONFIGURATION] My original configuration was just an older Playbar. Later, I added a pair of Ikea SYMFONISK Bookshelf speakers to this Playbar product, a single "Room". Side note, which I'll discuss later - I don't know if I could have added the stereo pair of surrounds separate from the Playbar.

I next acquired the Amp and added Sonance architectural speakers and a pair of third party speakers in a new "Room". I recently added the Gen 3 Sub and associated it with product Playbar (with its attached SYMFONISK Bookshelf speakers.)  With both Rooms grouped together the Sub audio level menu as accessed from product Playbar worked fine.

As much as the Sub added a great new dimension I thought I might be able to get more control over it by disassociating it from the surrounds (where it is physically located near) and connecting it to the Amp instead. This turned ou to be a mistake as this now rendered the Sub audio menu unusable and crashed the Android S2 app. Deleting and reinstalling the app had no effect. (btw, I had no interest in reverting to a previous app version.)  In my new configuration the Sub, while continuing to function at the same audio level (as previously setup) was no longer controllable in its Sub Audio Level menu from product Amp.

My solution was first to remove the Sub from the Amp product. Fortuitously, I also removed the SYMFONISK stereo pair from product Playbar as well.  Sonos then offered to add the Sub which I then connected back to the Playbar as before.  Sonos now offered to create a new SYMFONISK stereo pair: "Surrounds (L+R)", now completely separate from the Playbar.

At this point I now have three Products grouped together in "Living" Room:
1- Amp+Sonance+Front-3d party associated with product Amp
2- Playbar (+Sub) associated with product Playbar
3- Surrounds (L+R) associated with products SYMFONISK Bookshelf (Right) and SYMFONISK Bookshelf (Left).

This configuration allows the Sub Audio Level menu to function correctly when accessing it from its associated Playbar product as before. In retrospect I ended up just removing the Ikea SYMFONISK Bookshelf speakers from Playbar and creating a new surround pair separate from the Playbar. I don't recall having that option with my original configuration as I believe the surrounds needed to be associated with a product - someone correct me.  The end result is I have the better control over the Sub that I was originally seeking.

This solution worked for me and hopefully this helps someone diagnose and solve their problem with the Sub Audio menu crashing their Android app.

Good to hear the setup is working well for you, but if the problem is that the app crashes when the sub is associated with the Amp, it doesn’t sound like the problem was resolved — it’s just being avoided by not associating the sub with the Amp? Apologies if I’ve misunderstood.

it should be noted that the speakers you refer to as your surrounds are not actually surrounds anymore since you’ve removed them from the Playbar, they’re just a stereo pair. If you group them with the Playbar when you’re watching TV  you won’t be getting 5.1 surround sound anymore; they’ll just be playing the same audio as your Playbar, possibly with a noticeable delay. All good if that was your goal.

No fix with 14.0.2 on Android, still not able to adjust sub volume on my Amp.  Otherwise the system works just fine, subs and all.  Using iOS is the recommended temporary workaround, surprise surprise.
