Sonos Music Library won't update

Provider shouldn’t make a difference, should it (although you say new hardware, too)? I mean, even if you disconnected from the Internet, the Library (and Connect) should still all operate internally.

(I can just hear the network engineers’ brains seizing up: Why would you ever be disconnected from the Internet?)

Yes, provider doesn’t really matter, but new gateway and home configuration is an additional variable, plus TV support is now over wifi instread of separate coax connected set top boxes.

I also had a lot more kit RJ-45 wired to my router in the previous configuration.  Now it is predominantly wifi connected.

Hi all,

This is a very long shot (almost tangential) for this discussion, but I’ll offer it in case it helps someone find a solution.

I was led here with a Google search for “iTunes Music Library.xml.” I’m wondering if Apple has changed something in the structure of the XML file, rendering that file incompatible with some equipment. I’m experiencing some problems described here but on a different device: 1) changes to my music library are not being picked up, and 2) I am (somewhat) without my library. 

Although I own Sonos equipment, I’m currently troubleshooting a Garmin smartwatch.

(Please understand, I’m not asking this group for help with my Garmin device. I’m simply offering these details since the symptoms are somewhat similar, and I’m wondering if the XML file might play a part.)

I use iTunes on Windows 10 to manage my music library. Garmin’s software no longer sees any of my music when I use the current iTunes Music Library.xml file. However, I can pull up an old XML file from several years ago, and the Garmin software still reads that with no problems.

For the original poster and others in this thread with problems, did your Sonos problem appear after a specific iTunes (Windows) or Music (Mac) update? My old-but-still-usable xml file was created with an older version of iTunes. I’m now running the current Windows version of iTunes, 12.12.2.2, which was released October 29, 2021. I’ve recreated the file multiple times, but my device does not recognize anything from the library (songs, playlists, artists, albums, etc).

As I said at the opening, this is a long shot. However, IF Sonos does use iTunes Music Library.xml to get a current snapshot of the user’s music library, AND IF the structure of this file has changed somehow with a new version of the software, that MIGHT be a contributing factor or at least something worth considering.

Good luck to everyone troubleshooting. I know it’s frustrating.

Hi

So I have some good news to report. Doing some online reading I discovered the http interface to my individual SONOS components and was able to understand a bit about the topology and where my problem was.

Basically http://x.x.x.x:1400/support/review  where x.x.x.x is the IPv4 address of the component of interest and once there you can click on network matrix.  Typcially a class ‘A’ (10.x.x.x) IPv4 private address.

One thing I had not realized was that the spanning tree that the SONOS network converges upon can see an individual component using both the wifi and the wireline interface.  In my configuration it meant the hardwired play 3 in the office was also the root bridge of the spanning tree and was using wifi as well. From the network matrix reports (going through the components one by one and simply looking at the color codiing) I was able to discover it had a high ANI (ambient noise interference) value to some of my components. So the longer it took to catalog my library, the higher the liklihood of an unrecoverable communication error. Simply repositioning the play 3 in the office to get a lower value cleared things up.  Mentally envisioning line of sight to the other components helped, so try to avoid large metal objects like fridges and bathtubs. So while I had great bandwidth to some of my components as measured using tools on my iPad, the actual connectivity was crap from the POV of good enough for music.

So all is good in my world. Hope this helps!

In a similar boat here. The controller will no longer recognize my external drive and i am without my library. Very frustrating. 

Hello! Did restarting your router help you?
