Sonos Can't Find Music Library (Computer Not Found)

Similar problem here. Suddenly Sonos PC software and iPhone/iPad controller were unable to find my music library on my NAS, what it did for month. It took me two days reconfigurating, deleting, reconnecting and suddenly, without an understandable reason the library was found under the same route....... very strange

I've had numerous calls with Sonos over the last two months, and what is emerging is that there is a problem in the sonos interface with Mac products overall. I'd be interested to know if those who are writing here are on Macs or PCs. My problems started to arise when I migrated from a PC to a Mac. The last tech support person with whom I spoke said directly that the SBS form of file sharing that Sonos uses does not interact smoothly with Mac products, but "hangs up," so that, if you are trying to use the sonos controller on an iPad or iPhone, it may not work. He had a workaround for this (turn off file sharing on the PC, wait a bit, turn it on again), and it seems to work, but of course this defeats the point of using the iPad or iPhone controller, and doesn't at all address the underlying problem of trying to play directly from the Mac computer. I urge everyone to raise this if you call tech support, as it appears this should not be treated as an individual problem specific to each of us as users, but rather is a wider problem that needs a systemic fix.

I am having exactly the same problem and am at my wits end. Having persuaded my wife that she could listen to all our music in one place and having thrown our 15 yr old CD system out, I'm looking pretty stupid. What a nightmare... the error message I get is The computer "(null)" cannot be found, Help please before divorce proceedings commence

Hello, The network name that Sonos is finding for your computer, "(null)," is most likely not matching what your computers name is under Sharing. To fix this problem you will need to rename the computer by clicking on the Apple icon > System Preferences > Sharing > Computer Name. Type a computer name that is 15 characters or less with no spaces or punctuation. Once you have made the change you will need to restart your computer. After the restart try to add your music library to Sonos again by going to Manage > Music Library Settings > Click the "+" icon. If you receive an error message please submit a diagnostic.

Scott: Nice of you to respond to those of us who are having this problem. Just as an FYI to you, Sonos worked with me to change the computer name twice (even though it was fewer than 15 characters to begin with), and the problem nonetheless persists. Please see my comment of about 5 days ago on information I've gleaned over time vis-a-vis this problem. It appears to be systemic and may be specific to Sonos interface with Mac products. (FYI, I am going to have another support session with a level 2 tech upon my return from traveling, and we'll see what transpires, but I pass this along for troubleshooting purposes in the meantime, as the problem does seem to be systemic, not individual.)

I am having this problem as well, and I am using a Windows 7 PC. I have changed the name of the PC and updated my firewall settings. Still no luck.

Hello Michael, What is the error message that you receive when attempting to add the music library? Could you try adding the music once again and submit a diagnostic of your system after receiving the error message once again? You can find instructions on how to submit a diagnostic here: https://sonos.custhelp.com/app/answers/detail/a_id/142.

Same problem, firewall is fine, computer name has been shortened and contains no special characters, and still get the error message that my mac can't be found. Diagnostic #: 3038051 Any help totally appreciated.

Ok in the end we contacted the company who fitted all our sonos stuff after months of trying on my own to fix it! If there has been a power cut at any time ie storms etc it can cause the connections to only go to default. Therefore not accessing the full misic library. Inspire who fitted mine took the box away rebooted it and hey presto I now have h full access to my music library and a whole lot more. It can also be a lost connection don't ask why they just wear out Apparently!

I have the same problem - diagnostic submitted - 3047318
