Probably, your CD-player has it's own way of handling audio throught
hardware, mp3 needs to access the /dev/dsp device, which I asume you
don't have (check by typing: cat /dev/dsp). This will probably generate
an error message. The solution may be to either locate the proper module
to insert, or recompile your kernel. Try: modprobe sb
It might also be a matter of IRQ collisions or something, since a
Mandrake installation really ought to detect such a card. Check by
typing cat /proc/interrupts
Typ modprobing the module with different irq= flags.
good luck!
