I've made a crude recording of the Soundblaster card and of the
Integrated Sound system doing AFSK RTTY.  I had to record the sounds
from the computer speakers on my iPAQ and then transfer back to the
computer using the iPAQ and computer mic - all things considered, you'll
get the point.  Goldwave will let you choose different devices for
recording and playback, so at first I thought maybe I could use the
Soundblaster to directly record the output of the Integrated Sound, but
I never figured out how to make that work.  The recording is about 0.5
MB and is at http://wa9als.mystarband.net/soundcards.mp3.  The AFSK is
being generated by MMTTY.  I rarely use AFSK anymore, but this was
another way to look at the wierdness of the Integrated Sound system -
thanks Chen.

As someone suggested, I think it's time to ditch the Integrated Sound
and get a 2nd Soundblaster card!
