This just started happening to me, my Sonos won’t update my music library. If i delete my music folder and re-add it will be have everything in there that should be, but if i add more music (mp3s, which i do almost daily) and have it update, none of the additions show up.
my music’s on a macbook running big sur 11.6
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!
