In those days CD drives could output the audio as analog or digital signals separately from the data bus, using a cable that connected directly to the sound card for zero-overhead music. Commodity CD drives on the PC go back to about 1992 and playing CD audio would have been prohibitive overhead for contemporary CPUs

It was quite surprising for me when I found music from the CD drive kept playing after I shut down Windows 95.
