Sound In Problems
1 Audio recording quality is poor, a high level of background
noise is noticeable, or no sound is recorded.
2 Open the Simple Sound Control Panel (found under the Apple
Menu). Select CD Quality under the Sound menu to minimize
noise on the internal microphone. Did this solve the
problem?
Yes: If the initial sound in problem was with the sound control
panel; the problem is solved.
No: Go to next step.
3 Reseat the 5-connector audio cable on the outside of the A/V
Interconnect board. Looking a the A/V Interconnect board
from the outside, the audio cable is the black connector
located on the left.
4 If the background noise continues, install the microphone
gasket (922-3679) that provides an improved seal. The
gasket is placed on the front bezel, around the microphone
opening. Refer to Take Apart, “Installing the Microphone
Gasket” or TIL article #58053 for additional information.
