Hi, I recently added a new pair of Sonos SLs to my system that had just one pair, and noticed I was getting time outs from my NAS when trying to play music from my Music Library on the NAS. The playlist would skip about 10 or 20 songs and then finally play one. I’ve traced this problem to the elected sonos speaker in each pair opening up a large amount of SMB connections to my NAS (more than 15 each). On some older NASs, there is a max connections limit (mine is just 50 per share), and over time considering other stations may connect as well, it exceeds that limit.
Why does Sonos need to open up 20 or so connections for each speaker that is playing music from the local NAS Music Library just to play a single song, and is there any way to limit it? I can’t see that it would need 20 connections from a performance perspective.
Here’s an example of what I see on the NAS server coming from the lead speaker in each pair:
