AC97 sound card needs "external amp" ?

[Sean Bruno]

Just ran the sound card detection app to see if audio is working.  For
some reason I need to check the "external amp" selection to get any
audio at all.  

I don't think that this is correct, but can someone else check to see if
this is true for them?

00:1f.5 Multimedia audio controller: Intel Corporation 82801DB/DBL/DBM
