Anyone have a suggestion for a decent sound card? I've tried three
(the internal, a Creative Soundblaster external, and Turtle Beach
Audio Advantage SRM) and all have severe, but different, problems.

It would help if you told us what problems, and what you want to do with
that sound card.

It's used in a audio test fixture (http://www.ymec.com/) to set up
a hybrid circuit. The internal sound card has sort of 5MHz
oscillations that feed through the audio circuits (still don't
understand it completely) and screw up the distortion measurements,
though the sweep is clean. The SoundBlaster external has about
20dB of amplitude modulation on its outputs when the software is
sweeping. The inputs see the same sort of thing but not even in
phase so I can't just divide the two. The Turtle Beach unit has
horrible distortion (they dodn't even specify the codec - wouldn't
be surprised if it were only 8 bit).

I have 2 Creative soundcards in this PC, the cheapest one is the best one.
Problems? What problems? It all works...

I do not understand how your problems are occurring, it is rather
contrary to the basic design of these sound cards.

No, the primary design consideration of PeeCee quality sound cards
is COST. The secondary design consideration is also COST. All
other considerations are way down the list behind COST.

Just the same try looking in the semi-pro low-pro audio region like
RME Hammerfall. The kind of equipment used to make a compromise home
studio.

Others have suggested some alternatives, as well. I'm making do
with the Turtle Beach SRM but my distortion measurements are
useless. I'll see if the boss wants to spend money. Too late for
this design though.
