Unable to locate audio profile '0

I the "Introduction To Torque" tutorial when adjusting the "Master Volume" in the Option Dialog, there is no sound. I check the Torsion "Output" window and get this error:

Unable to locate audio profile '0'

When stepping through debug it gernerates the error on this line:

$AudioTestHandle = alxCreateSource("AudioChannel0", expandFilename("~/sounds/testing.wav"));
alxPlay($AudioTestHandle);

I thought it could not find the .wav file, so I changed it to this and I still get the error.
$AudioTestHandle = alxCreateSource("AudioChannel0", expandFilename("~/data/sounds/testing.wav"));
alxPlay($AudioTestHandle);

being new to the Torque Game Engine. Why isn't this working?
