CD-Recordable (CD-R) and CD-Rewritable (CD-RW).

software’s documentation and check that the hardware 
configuration meets the program’s needs.

Sound system problems 
No sound is coming from the computer’s speakers.
Adjust the volume control.
Try pressing 
Fn + Esc
 to see if volume mute is disabled.
If you are using external headphones or speakers, check that 
they are securely connected to your computer.
The computer emits a loud, high-pitched noise.
This is feedback between the microphone and the speakers. It 
occurs in any sound system when input from a microphone is 
fed to the speakers and the speaker volume is too loud. Adjust 
the volume control.
