Well, interesting you mentioned this. I have this audio cable installed
and after cdcontrol "told" the drive to play the audio CD, it is on the
CD audio channel of the sound card (and the mixer channel CD, of course).
I'm not sure how this is handled via the ATA cable where the CD drive
usually is connected, or the SATA calbe, if it's a newer drive. Or, to
make it more complicated, when the drive is a SCSI cable; I don't think
SCSI transmits audio data via the SCSI cable...

At least the drive should show the typical "playing activity" which can
be checked using a headphone on the drive's front connector (if it has
one).
