[phobos]

Hi to all!
i have a small but irritating problem, wondering if someone knows the answer.
i have re-installed LM7.0 this mornnig.  it all went well exept for one thing: 
i can only play cd's (music) when logged in as a root.  every time i get error
mesage re: permissions on my cdrom.  i have tried changing permissions but it
didn't solve the problem.  any advise will be greatly appreciated
