Operating Basics
Using the microphone
You can use the built-in or an external microphone that connects to the
microphone jack to record monaural sounds into your applications. It can
also be used to issue voice commands to applications that support such
functions. Since your computer has a microphone and speaker, "feedback"
may be heard under certain conditions. Feedback occurs when sound from
the speaker is picked up in the microphone and amplified back to the
speaker, which amplifies it again to the microphone.
This feedback occurs repeatedly and causes a very loud, high-pitched
noise. It is a common phenomenon that occurs in any sound system when
the microphone input is output to the speaker (throughput) and the speaker
volume is too loud or too close to the microphone. You can control
throughput by adjusting the volume of your speaker or through the Mute
function in the Master Volume panel. Refer to your Linux documentation for
details on using the Master Volume panel.
Wireless communications

LAN and Bluetooth devices.
