I’m having a problem with sound files. Or more specifically the data held within them such as artist, genre, title etc. I say the sound files as the problem occurs across different applications (Rhythmbox, totem player, and anything else) I can't change the data, such as the artists name. I can get to the point to where I can see it but can't make any changes to it. It looks like something simple but I've looked around and can't find any settings. I even logged in as root and - same thing. This sounds like a simple problem. Any ideas?
