Hello. I'm new to Sonos. Just bought a Bridge and Sonos 5 system. I'm using it with a Linksys router.
I am having problem importing music into my library from my computer. I keep getting the "computer cannot be found" message. I have turned off the firewall, so I know that's not the issue. Any suggestions would be appreciated. Thanks in advance.

Standard advice is to ensure that the computer name does not have any apostrophes, spaces, or special characters in the name and is 15 characters or less.

Try removing the "-" in your computer name.

Welcome to the forums.

Sonos doesn't appear in MS Network Places. Please describe your network for us. Include everything, and say how it connects (wired, wireless, etc).


Hi ratty, thanks for you reply.

I'm on Virgin Media cable which enters via the WiFi cable router they supplied. Both my PC and the Sonos ZoneBridge are plugged into the router with ethernet cables. A Sonos:5 speaker is attached as a wireless component.

Thanks

Internet Connection Sharing has no place here, so disable it.

A bit of background please: what firewall do you have, and are you using any kind of VPN software?

I take it that you've downloaded the installer for the Desktop Controller and have installed it afresh. Is the problem that you can't see the Play:5 in the controller, or are you having difficulty with adding a shared folder to the library containing your local music?

Eliminate the Sonos wireless temporarily by wiring your Play:5 to the Bridge's second port, and then please report back.

Hi ratty

Thanks for your help. I will try again to resolve this issue when I return from holiday. (I tried to send you a private message to this effect but my Post Count didn't qualify me.)

Thanks anyway

Hi.
I have the same problem as the rest of you guys.
Have tried removing special characters from my computer name, turning off firewall, sharing the D:drive where my music is, moving a copy of my music to my c:drive and trying to Add the music from there... nothing worked.
My PC is connected via WIFI so I wonder is that a factor?
Please help!

It certainly could be, and in fact Sonos won't officially support a WiFi-connected music library owing to WiFi's variable streaming performance. Despite this many use such an arrangement successfully. Improve your chances by noting the recommendations about keeping WiFi and SonosNet apart in this earlier post.

Hi ratty

I am using Windows firewall, and I have checked that Sonos is selected in the application exceptions list. I have also tried disabling Windows firewall altogether.

I do have VPN software installed, but I'm not currently running it.

My problem is that I cannot add any of my music folders to the music library, either on the local C: drive or on an external USB hard drive. In all cases, I get the error mentioned earlier in this thread, that my computer cannot be found. The folders seem to be shared correctly as fas as I can tell.

I've tried connecting the Sonos:5 player to the second port of the bridge as you suggest, but that didn't make a difference. Having said that, I couldn't seem to remove the room it was in before from the Desktop Controller, so I don't know if it's still trying to communicate wirelessly. But, in my opinion, this seems to be unrelated to the problem, which is the Bridge being unable to see my computer.

Kind regards
Angus

This is peculiar and suggests some network problems. Did you simply plug the P:5 into the Bridge, or did you add it again by pressing Mute/Vol+?

But, in my opinion, this seems to be unrelated to the problem, which is the Bridge being unable to see my computer.

There are two sorts of network communication between your computer and Sonos: from the Desktop Controller to the player(s), and from the player(s) to the shared folders containing your music. They are entirely independent of one another and I'm trying to see which exactly is failing. The picture I have thus far is that it's a bit of both.

1/ Is File and Printer Sharing ticked in the Windows Firewall exceptions list?

2/ Sonos doesn't get on terribly well with VPN software. If it's not in use try removing it entirely. Simply disabling it usually leaves the driver loaded.

3/ Give your network a full restart. Power everything off, start the router then work outwards. Wait for each device to boot fully before moving on to the next.

If this still brings no joy, submit a new diagnostic after another failure and file a support request quoting the confirmation number.

I was having the same problem as the other people in this thread on a mac with OSX 10.6.8. I tried changing the computer name, the WINS network name, changing the wifi channel both for router and Sonos, tried to access the share via \\machinename\Music share, etc.etc. Nothing helped.

Then I thought using the IP address, and I tried to enter \\192.168.1.65\Music as a NAS shared folder, and this worked. Note also that even though my system is in Italian, and therefore the music folder is shown as "Musica" I had to use the english name (which is probably the real name of the system folder).

Overall, a pretty awful user experience, but at least I'm happy I had it working. Now I' m only hoping that the router won't frequently assign a different IP address to the machine.

I just thought I would report that here for other people to try the same workaround.

You should be able to set the router up to either a) give an indefinite lease time to the IP or better b) associate a single IP address with the machine via the MAC address of the network card

Infinite leases are not recommended. Devices effectively 'steal' the IP and never give it up.

I solved this by using the IP address instead of the name of the machine. There seems to be an issue with the name resolution over wireless but the IP address worked fine.

Same problem. Diagnostic number 3244015.

The Sonos will stop playing in the middle of a song.

I do hope you didn't wait for 4 years from the last post to sort this!

Nope it was the first Google result so thought I'd update it so someone else could find it if they had the same issue 😃

If you haven't already, install the PC/Mac software and try the install from there. If that is failing, make sure your music folder is being shared. This means you have to turn on sharing and enable the folder for sharing. Then do a manual setup of your music library and when prompted, browse to the music folder. If this doesn't work, something unique to yor system is blocking you and the best bet is to contact Sonos support. The will get you running in no time; they really are that good.
Ben_From_DC,

The firewall FAQ can be found at https://sonos.custhelp.com/cgi-bin/sonos.cfg/php/enduser/std_adp.php?p_faqid=692

Some VPN software can also give rise to the reported behaviour.

A clash between WiFi and Sonos can account for these symptoms too if the computer is operating wirelessly. Note that accessing the computer's music library via WiFi is not officially supported. It can work, but one compromises the benefits of SonosNet. Best results are usually obtained by setting WiFi to channel 1, 6 or 11 -- choosing one not used by Sonos -- and avoiding '40MHz'/'wide'/'turbo'/'up to 300MBps' modes.

Hi,

I am having a lot of trouble setting up my new Sonos Play: 5 system.

Whenever i try to add a music share (my iTunes music library), i always get the following error:

Couldn't share music in the folder ~/Music/iTunes/iTunes Music.

The computer "MACBOOKPRO-0F3E" cannot be found.
Make sure that Window sharing is turned on, and that the computer is on your network. Please also check your firewall settings.

Now, if that error doesn't come up, i get another one of the Sonos desktop controller itself at the bottom saying:

'//MACBOOKPRO-0F3E/Music' is no longer available. No indexing was performed on this share.


I have turned off the firewall completely on our router (home hub with BT Infinity) as well as on the mac.

Followed all instructions in the set up enabling File sharing etc. Also running all the latest software/firmware on the devices.

Im running it from a MacBook Pro running Lion.

Ive sent an email to support, but thought i'd hit the forums to see if there are any home remedies 🙂

Hi Mitchy,

I've sent an e-mail to your registered e-mail address to get in touch regarding this issue, I have a feeling I know how to take care of it, but need a diagnostic to confirm.

Hi Guys/Gals,

Thanks a lot for your quick reply!

Its safe to say it all working now.

Turns out the problem was with my computer name "Darryl's MacBook Pro". Changed the name to "Margerie" (we have a tendency to name things) and it just worked after that.

Thank you so much, you have reduced the amount of grey hair I am yet to receive!

Hi Guys,

I tried removing characters from my computer name as well but this problem still persists.

Any other ideas?
