I’m one of those smug, self-satisfied people who has auto-update turned off, and who expected to be able to stay with the old app until this mess has been sorted out. But no - even with auto-update set to “off” my app has been updated and now my TuneIn stations won’t work and my Network Shares won’t work. Just the helpful error message “Something went wrong”.
However… the open source client NOSON still appears to work perfectly. I can still play tracks from my Network Attached Server, can set alarms, can play all of my TuneIn based radio stations - can even play music from the PC’s local disks.
Of course it’s only a solution if you already run one of the common versions of Linux (you can install a current version of NOSON for free straight out of the standard repositories), or with Windows/Mac, if you’re willing to run it under something like VMWare - not technically difficult but a bit of a pain to have to do.
But it did make me wonder - if a one-man development team can do such a great job and keep NOSON running and updated for a decade, is it possible that someone could port it onto Android? That would give a long-term fallback, in case this current debacle is not just ineptitude on the part of Sonos, and instead an attempt by them to show us, the customers, that they control our devices, and not us?
