Adjust the volume control.
If you are using an external headphone or speakers, check that
they are securely connected to your computer.
In TSETUP, check that the sound function is enabled.
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

Mixer Utility (default Enabled), may cause feedback. Revert to the
default settings.
