First of all, the cdplayer has to have the cable running from the
audio port, on the back, to the appropriate spot on the motherboard
or sound card, or there's no hope. Assuming it's cabled correctly,
the next stop, after "cdplay play", is the mixer chip...

"mixerctl -a" will tell you the knobs available on your mixer. You may
need to turn the mute off, with "mixerctl -w inputs.cd.mute=off", or
you may need to turn the volume up, with "mixerctl -w inputs.cd=255".

Actually, you can listen to audio, even without the cable, using the
"mplayer" front-end to "cdparanoia", but the straightforward way is to
run the cable to the motherboard.
