I received this computer today and the internal microphone hasn't worked so far.
I have tried Google hangouts, Skype, Audacity, and just runningto record audio. All I hear from the microphone is silence with an occasional crackle.Code:arecord test.wav
When I plug in a USB headset with microphone and select the external microphone in the Sound Input tab I can record sound just fine.
I currently suspect this is a hardware problem. Is there anything else I should do to further test this hypothesis?
