Audio – Microphone Port Testing
The onboard audio MIC-IN port was tested using a Logitech Internet Chat Headset. Spoken words were recorded from the Windows Sound Recorder found under the Accessories\Entertainment folder in the start menu within Windows XP. The recording was made with the Microphone Boost option disabled, then enabled. The Microphone Boost option is found within the advanced menu under the microphone section with in the Volume Control Menu.
The microphone playback was inaudible without the microphone boost option enabled (edit by me: should have said disabled I would think). When enabled, playback was audible and distortion free. There was also a Front Panel Mic option that was enabled by default. When this was enabled, no sound was audible in playback, and there were no level readings.
