When squeezecenter installs it creates a user ’squeezecenter’ belonging to the group ‘no group’. This can be a permission problem if for instance, like me, you have squeezecenter running on a server where other users may be the owners of music folders and files that you want squeezecenter to see.
I have various Windows machines that map to the server music directory under a specific user group, for instance ‘media’, that the squeezecenter user is not a part of. Squeezecenter cannot see files created by users in the ‘media’ group because my Samba config file specifies that users creating folders or files on the server not give read access to users outside the group.
The solution:
Add the squeezecenter user to the ‘media’ group.
open a terminal and become root.
type
‘addgroup squeezecenter media’
where media is the group that users connect to your server under.
Changing the Samba config so that the create permissions give all users access to files should also work.
