CDrom will not mount sound or music CDs; only sound CDs, for data and video CDs it mounts and plays them correctly.

[MTA]

I had a previous CDdrive that gave me that problem,that is,it stopped mounting sound and music CDs,
so thinking that it was the fault of the CDdrive,I bought a new one and installed it, but the problem remains exactly the same as before.It mounts and plays data and video CDs correctly but does not mount sound and music CDs.A line appears on the side of the file menu that reads "Audio disk" but when I click on it it says that the location is not mountable;when I rightclick it a menu
appears that gives me a few options like mount,eject,format,etc.,but when I click on mount a message appears that says "Unable to access audio disk Location not mountable" and no icon appears on the screen.When I asked for help,"Ask Ubuntu" had me to install "regionset" and I set it to 2 and some other deencryption program which I do not remember how it is called which,by the way, I think it is giving me troubles with video playing;but that did not help neither.So here I am waiting for some help.Thanks.
