Select the Audio tab and make sure the Sound recording default device is set to Line in/Mic in.
Click the Volume button in the Sound recording area.
Set the Recording volume to be as low as it can possibly go without being all the way down.
Leave the recording control mixer dialog open and go back to Biopac Science Lab.
