I've been struggling with my Sonos installation on and off since I've had it - two years now.
I gave up with the wireless link and ran a cable directly from my router some time back and that fixed some of the poor connectivity. Recent software updates now mean that the IOS apps connect every time, instead of occasionally, so that's an improvement.
Now onto the recent issue - no more music library.
Re-scanning the library after the recent update meant I've lost connection to it, and I cannot figure out how to get it back.
It's not the Windows 7 firewall - I've added a line in the "inbound rules" for the 'sonos.exe' in program files.
I've un-installed and re-installed Sonos.
The radio stations still work on Sonos.
When trying to add the music libray using \\pc-name\share-name, and 'next' with or without the username or password, it fails, both on my IOS app and on the Windows Software.
I'm wondering if there are some old settings within the PC software that are wrong and stopping this working. I rather think it would be useful if there was a tool to remove all the Sonos settings (PC software) - probably there should be an option when un-installing it to remove all user data (or not). Each time I un-install & re-install it, it has remembered my playlists and favourites, and I wonder if it's remembering some other stuff that is causing the problem. I went through my 'appdata' folder and removed all references to Sonos, and also in the registry in desparation to no avail. On re-installing I still get the Serverstack/Error 900 (I did make that reg change a year or so ago, btw) and I still have my playlists.
Anyone else figured this out yet?
