About a year ago odd things started happening on my stereo, for some reason some of the newer music CDs wouldn't work, the stereo couldn't detect the tracks, however they played OK in a different CD player and on my laptop. This would occur consistantly for a CD even if it was brand new (no scratches or dirt). Sometimes one disk out of a two disk set would play and the other wouldn't! I tried burning a copy of an affected disk to see if it was a fault with the actual CD (CD-Rs normally play fine in the stereo). The copy has the same effect on the stereo as the original. My stereo is quite old, have their been recent changes in CD formats that might account for this effect? Copy protection perhaps? Though I don't see why a company would go to the trouble to copy protect one disk of a set and not the other(s). Has anyone else encountered this?
A few thoughts Check that the lens is clean on your stereo cd player and not clogged with dust. An old Denon player of mine was very difficult to clean due to a lip around the lens. It could be something to do with copy protection but in theory this should not be affecting an old audio cd player. Copy protection systems vary but most seem to incude the idea of creating a multisession cd with the final session left open or pointing erroniously past the end of the disk. This is intended to fool multisession aware players - whether it does or not depends largely on the hardware - but simple audio cd stereos should be unaffected as they just read the information from the first session. Take a close look at the cd covers. Information about copy protection is often included in very tiny print. Rather than copying an image of the cd, it might be a good idea to make sure you have a clean copy of the music data, for example by ripping the data into wav files with cdparanoia -B then using your favourite burning utility to write the files to a new cd in a single closed session.
