No.

Audio CD's are played by turning your CD-ROM reader into a "dumb"
player. The CD Reader itself engages and plays back the Audio CD.

Output takes the form of either (or both) a DIGITAL, or ANALOG signal
coming from the back of the CD-ROM reader. This signal is fed to the
sound card via a separate cable. If your CD-ROM reader and audio cards
are SPIF capable, you actually might have two separate small audio
cables running from the player to the sound card.

One is an Analog cable, the other provides digital output.

When CD's are played back the audio signal feeds into the sound card's
on board mixer and then goes out to the speakers. This circumvents the
CPU altogether, placing almost no load on the computer. If you powered
your CD-ROM reader directly you actually wouldn't even need the
computer.

Certain Rippers on the other hand can grab the digital data directly
from the audio cd. They do this by utilizing code that can interpret the
audio data as a file system. The computer then can copy the audio data
to the hard drive (or software) without passing thru the sound card at
all, or undergoing D/A,A/D conversion.

The resulting MP3 files that the rippers create can be listened to on
your computer via software that directly feeds the sound card's D/A
converter.

Thus you can have a CD-ROM reader which may be missing it's audio
cables, yet you can still digitally "rip" your audio music to MP3 files.
You can also play those files back without problems and hear them fine.

However if you insert an audio CD into the player and attempt to play it
directly, you hear nothing, since the feed cables are missing.
