Double check your settings in the Sounds applet [on the control panel]. The
couple of problems that I had with setting up two sound cards were all
related to Windows. I had only two sound cards installed but Windows gave me
three choices when selecting my default card. One of them caused my whole
system to choke and the other two were the actual sound cards. I'd check
this setting and make sure that Windows hasn't grabbed your other sound card
[for whatever reason] and made it the default. I also found that which PCI
[I'm assuming these two cards are PCI] slot the cards were in made a
difference. As a last resort you might want to try swapping the two cards
around.

Another solution for the ground loop problem that I've heard [from this list
I think] is to connect the chassis of your computer to the chassis of your
amp. I haven't tried this yet but I think someone else on this list has.
It'd certainly be worth a try, and would be cheaper than buying an isolator
from RS. Although if your computer is far from you amp it might not be worth
it if you have to run another wire.

  I tried the two sound card thing with a SB AWE 64 as default and a D-man
card with RCA in and out to play mp3 with cdj.  Well, It worked right the
first after install.  However, after that the default card took over and
played everything, including mp3 with cdj!  The settings in cdj still showed
the auxilliary card in control, but the proof is in the pudding.  Any
thoughts about this?

  Also, I have a terrible problem with hum when I put my audio out from my
sound card intomy Denon receiver for playback.  I have moved the unit and
even tried a Pioneer receiver and even changed sound cards and still no
help.  You Slinker's out all talk about your mp3/cd playback mixes,!  Are
you putting up with a pretty noticeable hum or have you got some magic
bullet?

  I have even tried digital out but that is a maze of output types like
spdif and electrical spdif and optical and even a new sony output from the
new SB Live! 5.1 card

  Thanks,
  Carl

    I use two SB PCI cards. They have two slightly different model numbers
but from what I can tell are exactly the same. The setup was much easier
than expected. My HA server runs Win2K Pro, and already had one SB working.
I just added the second card, Windows found it, and everything pretty much
worked. I was ready for some major problems, but I didn't run into any.

    You set one of the cards as the default sound device. Windows will use
this card for all of the system sounds and most other programs will use this
card for their sounds. But if you have a program that supports using a
different sound card, like CDJ [thanks again Colby], then you can choose
which sound card that program uses. If you're writing your own program
there's a document on Microsoft's site that explains how to choose different
sound cards using VB. I haven't really looked at it but on first glance it
seemed pretty straight forward.

    On my HA server I have all of the system sounds go to a small set of
desktop speakers, CDJ sends MP3 output to the other card which is connected
to my amp.

      There has been some talk about using two sound cards on this list.
Many questions come to mind.
      Do the choices of cards matter?
      What settings are needed?
      Can you direct different sounds to different cards?
      Thanks for your help,  carl
