Audacity - Record and Playback way too fast

Megan was trying to record using her EQ laptop and Audacity.
The files recorded played back way too fast.

The solution (After research and random computer button pushing)
Untick everything in the Transport menu

No idea why check boxes associated with what look like signal routing would affect recording speed.  Bug?

 "Software Playthrough" should not cause a "Chipmunk" effect, though I can see why it might.
If the computer has difficulty keeping up with full duplex sound then it is likely to cause bits of audio to be missing from the recording (drop-outs). If the drop outs are occurring very frequently then the resulting recording will play too fast because there is only a fraction of the data that there should be. As most consumer grade sound cards are intended for little more than playing computer alerts it is not terribly surprising that the sound card drivers are often not optimised for full duplex high quality audio.
 Maybe too many windows open and too much EQ security overhead?
