The two ways an optical drive can send audio off of a disk are:
1. Use the equivalent of cdparanoia to read the data off, do
error-correction and play through the DSP hardware
2. Command a CD DAC on the drive to emit music through an analog
connection to the machine's mixer.
If your usual method was (2), then a broken wire on the analog
connection is the likely cause. OR, perhaps the mixer input is
muted or turned to zero.
Try xmms, turning on digital audio extraction (CD-audio plugin
options).
