Music Cds

Hi all.

Something strange is happening with my 10.3 system. I can play and listen DVDs, I can burn CDs and DVDs, I can play and listen all kinds of audio and video formats, but my system cannot recognize audio CDs...when I insert any of them nothing happens, if I do it with a data DVD/CD or with a film in DVD everything goes fine.
What can it be? Thanks.

Ok, I think I know now at least part of the problem: it only happens to me with very recently bought CDs...I have just tested it:

1. I insert a very new one....I get the problem
2. I test an older one...NO problem at all !

I can repeat steps 1 and 2 as many times as I want, and the results are always the same. I guess new CDs have some kind of protection that my system 10.3 cannot break.
So, the question is now: is it possible to overcome that protection? Anyone has ever had the same problem? Could you also test and then comment it here?
