Check first if the direct audio cable is propperly switched to the CD
drive and to the motherboard.
If you get a system freeze you should check if the disk is OK, damaged
CD's can produce what we call 'trashing' and stay in 'uninterruptable
sleep' mode, which makes that you will be unable to kill the process,
as it is in kernel mode.
Another cause for this are dirty or damaged lenses.

You cannot access the CD drive with an audio cd is inside anyway either,
audio CD's des not belong to a file system which normal OSes can
handle, you can surely get a track list, but this is not accessing the
drive.

This only confirms that your OS is OK and that the drive has (prolly)
no hardware failures.

This is what I told you: "uninterruptable sleep", this is a feature
related to the linux kernel and the hardware itself, it can also
happen on windows, if you have a windows version available try to play
the same CD. Antoher cause of failure could be a damn DRM-protection.

Nope, it's hardware related and involves the kernel, the disc, the
drive and probably the DMA chips.
If it is a DRM issue, try installing the DRM modules shipped with SuSE,
if this solves the problem it's 100% sure that a cop protection is
isntalled, complain to the manufacturer, as a consumer you have the
right to be able to play the CD wherever you want and these protections
can avoid playing the CD on your car's drive or on some normal
non-computer based hardware.
