Hey @Cyclopops,

Welcome to the Sonos Community!

Sorry to hear that Sonos cannot play your music from your laptop anymore. While I’m not using a music library with Sonos, I do use OneDrive and know about a sync setting that might be the solution to your problem: “Always keep on this device” is an option when you sync OneDrive. This way OneDrive has a copy in the cloud, but you also have the files available locally for things like Sonos to access.

I think the best way forward would be to get in touch with Microsoft to help you out on that. Let us know, how this turned out.

Hope that helps!

Thanks Gabrial, I fumbled around and decided I’d copy my music files back to a new music folder on my C drive that Sonos was able to see and that works. 

Cheers

Hi,

I have been using your system to allow access from SONOS to OneDrive successfully since I had to abandon my MyCloud network disk (I have a SONOS 1 system and components so can no longer access it)and for this I'm very grateful so I'm emailing you with information which may be of use to you rather than a complaint of any sort.

Earlier this week suddenly I couldn't see all of the music subfolders in my OneDrive main music folder (called "Any Music"): SONOS would show about half of them and then no more. I have circumvented the problem by copying the ones it wouldn't display into another OneDrive music folder (which I have called "Any Music from K").

It seems that somewhere between the files in my OneDrive folder accessed by your system and SONOS displaying the available music a limit of 100 subfolders has been imposed. I say imposed because if it were a programming issue I would have expected the limit to be a power of 2 but I may be wrong.

I confirmed the limit of 100 because by coincidence I had 199 subfolders in my original "Any Music" and 100 in the new "Any Music from K" so I copied one more into this second folder and ... the last subfolder disappeared.

It was always the case when scrolling through "Any Music" within SONOS on my laptops there would be a pause at the point where the system now stops displaying, as if something was buffering, but then it would display the rest. This didn't happen if I accessed SONOS via my iPhone.

As I said I have circumvented the problem and will post this information on the relevant SONOS community noticeboards in case it is helpful to anyone else.

Thank you again for providing the SONOS-OneDrive solution, Tony Cornah
