Bug Description
I'm not sure if this is in alsa-driver, I think I'm using pulseaudio. Also, I'm not sure why this shows up as "Realtek"... I think it's Intel HD Audio or something.
I don't hear anything I'm actually trying to record, just a loud high-pitched whine / squeal. Same result with arecord, Skype, gnome-sound-
Sound playback works fine using the built-in speakers.
Using a USB Headset, sound recording (and playback) works fine.

Hi Adam, could you try the following:
Open gnome-volume- control (by clicking speaker icon, then sound preferences). Go to input tab and make sure "Internal Mic" is selected.
If this does not help, could you open a terminal, execute the "alsamixer" command, navigate (with arrow keys) to the "Input Source" item and make sure it is set to "Internal Mic"?
Please report back and tell us if it helped or not. Thanks!
