I am getting the same error, but I did not re-index the folder.

Some recent update to the Sonos app caused my local music library to disappear from available services. I went to the Sonos app on my Windows 11 computer to try to share the folder, using “Music Library Settings” from the “Manage” menu, clicked “Add”, navigated to the folder containing the library, and clicked “Next”.  After a few moments, I got the error “Sonos was unable to add the shared folder”, with the error code 913.

As with the previous user, this is in Windows, so the suggested solutions for MacOS do not apply.

Sonos, please fix this bug ASAP!!!!

What is the use of spending several hundred dollars on speakers when they cannot play any of my music??????

Why don’t Sonos comment publicly on these issues and make their next steps clear for all users?

SONOS is great, until it stops working, and then it’s crap. One hour waiting on the phone to figure why my music library disappeared and won’t let me reinstall it. ERROR 913. Thanks a lot, Sonos.

I got mine to work again about a week ago allowing all possible sharing options of my Music folder with the Sonos system on Windows. Yesterday evening, when swapping from music played from the local library to a Line-In for watching TV from an old Laptop (yes, I know… it’s an interim setup), I could see that the local library had disappeared from the new app on my phone, and voilà this morning it had also disappeared from the Windows Desktop App. I have no idea what’s exactly happening there and why it works some times and other times it doesn’t :( 
This is more than frustrating for someone who is very particular about the music they listen to and gets irritated easily by the wrong song on a radio station…. I dearly hope they can address the local library issue quickly with a new update

A quick search around the forum shows the following as the fix for error 913 - it’s  just a folder permission error on the PC…

1. Right click on the Music folder and click on PROPERTIES at the bottom of the menu.

Click on the SHARE tab and then click on the first SHARE button…

1. A new window opens and you click on the ‘v’ drop-down list option next to the ADD button.
2. Click on "Sonos Wireless HiFi System" then click on the ADD button and finally click on SHARE.
3. Open your Sonos app on your PC and add your music library.

I have this issue too.

I have returned the one Sonos unit just purchased. But would still like the make the others work while I research alternates to Sonos

According to Sonos support, the reason for this breakage is that they have, without warning, ended support for http and SMBv1 protocols for accessing network drives, out of a supposed concern for our security. Your network share must use SMBv2 or SMBv3 protocol. This is something you would adjust on the device which is doing the sharing. If, as in my case, this is not a Windows system, the proposed fix for Windows PCs will not be useful even if you are using the Windows application. So for instance, in my case, since my music is on a flash drive plugged into a Netgear router, I would go to the router administration page in my browser (192.168.1.1 in my case) and see whether there’s a way to select the SMB version level.

Hello,

I have received the exact same message and was unable to connect to my “Music” folder on my PC until I performed the following steps:

1. Right click on the “Music” folder
2. Select properties
3. Select the “Sharing” tab
4. Select Share
5. Select “Sonos Wireless HiFi System” in the dropdown box
6. Click on “Share”
7. Back at the top “Music Properties” dialog box click on “Advanced Sharing”
8. Click the “Share this folder” box in the upper left corner
9. At the bottom of the dialog box click “Apply” and then click “OK”
10. Go back to the Sonos controller and add your local “Music” folder

This worked for me.

Hope this helps.

This is a complete  joke for a product that is not cheap . Access to your own library should be a simple task . Not spending hours with tech support trying to resolve. I’m sure the CEO of Sonos is having a lovely weekend in the Hamptons while loads of us won’t be be to listen to music this holiday weekend . Why the hell don’t Sonos actually make a comment on this instead of leaving it to the customers sort out . Ahhhhhhhhrrr. 

I bought the One SL to playback from my music library. So impressed I bought another for he full stereo experience. Not cheap, but more than happy with the set up. Since the recent update I now have a very expensive stereo radio. Not happy anymore.

THIS WORKED!  Thank you!

I think that is my case: my NAS is a bit too old and it’s using SMB version 1 protocol. When visiting it from a Windows terminal I can adjust it for the connection, but in Sonos app there is no such option or known possibility, although I completely accept this security risk. I don’t have the plan to replace my NAS because I have too many devices connecting to it. I guess I have to replace my Sonos to another brand, then.

They did send out a warning, but IMHO, it wasn’t sufficient.  It merely stated that SMB v1 and HTTP sharing will no longer be supported.  They should’ve done more to let people know in less technical terms what to expect and how to rectify.

Did not work for me. This is an insidious issue that Sonos should have solved a long time ago.

Finally stumbled on a fix, I hope… for my Windows 11 system anyway. 

Give all the proper permission for file sharing in both the Share tab and the Security tab to the additional user and Sonos Wireless Hifi System. For good measure make sure SMV1 is turned off but it comes as default for Windows 11 anyway.

My Sonos S2 is Sonos_79 1-53290. Yesterday (!!) it allowed three options for the music folder to reside in: OneDrive/music; ”Another folder or drive connected to my computer”; NAS.  As a Hail Mary, I copied some MP3s to the first option and it worked. Today(!!) the first option disappeared from S2. But moving the music folder to OneDrive/music continues to work. Why it makes a difference between Option 1 and 2 I don’t know. Sonos help desk missed this one. I just stumbled on it. But for someone who does not have large enough storage in your PC C:\ drive, you may be out of luck.

How can Sonos churn out such garbage software? Wait till they roll out another new version of the controller and we will have to do it all over again. I still haven’t begun to tackle my Play 3 issue yet. I don’t have the energy to waste my life on Sonos so soon. Maybe I should burn my Play 3 and go back to cassette tapes and a boom box.

Thanks

I have a Windows 11 PC S2 controller. Three pieces of Sonos (crap), an old Play1, a Play 3 and two Roam SL. Having spent quite a few hours fixing another issue 2 weeks ago, now new issue of PC music folder unable to be recognized by S2 … same thing... Error 913. What started it was my Play 3 got kicked out of the system for no reason. Then using the now infamous Version 80 mobile app (there is no other choice), I tried to add it back to the system. It said my Play 3 was not registered. 

To simplify matters, the Sonos help desk, and I agreed, unplugged the Play3 and concentrated on Error 913. No dice. They claim they have escalated this and someone will email me to set up a time to problem solve it. Have not seen this yet … they probably don’t know how to fix it yet!!

I did what worked for some above -- gave permission to “Sonos Wireless HiFi System” ---this is completely new to me. I had to type Sonos and search before it even comes up. Does not work.

The Sonos help desk did something else as well -  under Windows Setting/Users, it added another second user besides myself … his claim is then just sharing the music folder with this second user will bypass all the Windows/Norton firewall issues. Same thing, gave all the permissions. Still no luck.

Anyone found anything else? Why do we have to go through this twice a month. It’s simply casting music off your hard drive!!

Thanks

Down On Sonos

That worked for me also after a long wait to get to tech support and not being resolved. Thanks, my music plays again!

Realised later on that I just had to re-boot my laptop. It’s all working again but it appears that it keeps crapping out every now and then, potentially related to updates in the new app interfering with the existing setup. So, making sure that from the Windows side, the music directory is shared to the Sonos system at multiple levels appears to salvage playing of local libraries. With the occasional hickup Should get us through until the June update for which they promise local libraries back, though :)

Thank you! The music file sharing instructions as given by several of you in this thread worked for me (Windows 11). After countless “error code 913” tries I can once again play my iTune music files on what I was calling my expensive paperweights these last few weeks. Why couldn’t anyone from SONOS provide this relatively simple solution?

Having read many of the posts about this problem, and having it myself, I have sent the following email to the CEO. It will be interesting if I get an answer, and hopefully a solution:

Good morning

I have returned from a business trip to find that I can no longer play my iTunes library through my Sonos system. I have used this facility succesfully for at least 5 years.

I have tried everything to remedy this, but the iTunes folder will simply not load - and error code 913 is shown every time. I have checked the file, and sharing is enabled / allowed. I run Windows.

Looking on your forum, I see this is a new problem and everyone seems to have it who tries to play their iTunes library through Sonos..

What are your plans to rectify this please? If you are not going to rectify it, my Sonos system is no use, and I really would not expect that.

I would also ask, why does Sonos not reply to the thousands of comments on your own platform (Sonos community) relating to this issue?

I look forward to your reply, and a solution.

And what's the entry you have for what I assume is ‘Music’ in the app for the library? 

Ahh… and that on your Microsoft OneDrive?

What happens if you create a new directory under c:\users\richa\Sonos for example and share that ? 

Part of the issue could be sharing what is not a local drive out again over a network… guess, but have seen double sharing cause issues on many things before… 

Actually here is what I am trying to add but when I hit next the infamous 913

If it says “expected wait time” of 75 minutes by the automated answer, it will be at least an hour and a half before Level 1 picks up! Don’t bother, they simply don’t have the answer. They read about the fix (for most Windows users) from here just like us. I am supposed to get a Level 2 scheduled appointment (re-escalated a second time) but they have not honored that commitment -- I think Level 2 has no idea either. Sonos is truly disrespectful of its customers. Fend for yourself seems to be the answer. It will be a Harvard Business School case soon on how to destroy a franchise.

Thanks

Thanks to some extremely good comments in this thread I was able to solve this.

From this it is clear to me that with some clear and well articulated instructions, and some warning in advance, this would not be a problem.  As it is -- Sonos has really created a giant clusterfork for nothing.  What a ridiculous fiasco.

I never received any warning.  And just stating that is ridiculously inadequate.  They should have given detailed instructions.
