1 Setting Up and Using Your PC
Connecting Audio Accessories
If your PC does not have multimedia capabilities and you want to listen
to audio CDs on your CD-ROM drive, you can use the headphones jack
and the volume control on the front of the CD-ROM drive. To access
these controls:
1 Remove the CD-ROM drive’s font bezel by carefully pulling it off.
2 Replace it with the universal front bezel.
You will find a spare universal front bezel inside your PC (refer to page
38), or you can order one from an authorized HP reseller.
