I have that same problem with SuSE... I can get sound out of the CD drive in Windows, but not Linux. What I've found something that works, if you have XMMS... Right click on the xmms box that comes up, and pick Options, Preferences. In the I/O section, pick Audio CD reader. Then try playing through XMMS.
I didn't figure it out myself... I found it by googling and now for the life of me I can't remember the site, but whoever's site it was, thank you immensely...
Don't know if it will work for you, but I guess it's worth a shot.
