CD-ROM drive. The headphones will not pick up other sounds generated from
your computer or any external device connected to the computer, such as a
MIDI (Musical Instrument Digital Interface) keyboard.
When your headphones are plugged into this jack, use the volume control on
the CD-ROM drive to adjust the volume of the headphones. This volume control
adjusts the volume of the headphones, but not the speakers . If y ou wa nt to turn
the speaker volume down while using the headphones, use the volume control
program to do it.
