Curious, is there a particular reason why two soundcards are in use at the same time on this computer? I'm not sure since I don't own one(I have a Chaintech AV710), but an Audigy 2 ZS should be able to output to two sources at the same time one way or the other. My soundcard does, by means of either two analog line outs because it hasn't been set up to make use of any 7.1 features (Does the AV710 have any common use for 7.1?
I though it was better suited for stereo...), or by one analog and the other as digital by optic cable.
I have my rig set up this way because I use my headphone amp primarily off the DAC inside my soundcard, and because I have a speaker system wtih digital input and a card that can spit out analog and digital versions of the same signal at the same time. It's also set up so that I can use my headphone amp with my reciever when I want to have a higher quality output than my reciever offers out of its 1/4" jack when it's not pushing multichannel surround sound.
What you might try to do is find out if using the second card is even necessary, because one card is usually enough, unless you run musician-intensive applicatiions on your computer (running multiple midi keyboards, mics, DAT decks, amps, things like that). If you can use your Audigy to drive two devices, that should be more suitable, and if you want to disengage the other card to see if this is right for you, its not hard to do:
1.Go to your control panel
2. Go to system settings
3. Go to device manager
4. find the soundcard you want to change settings for
5. click disable device (in hardware profile)
6. Shut down your PC
7. remove the soundcard you just disengaged from your system
8. restart
This should remedy things for you, because more often than not running two cards is just not necessary unless it has to stay in there for reasons beyond your control. In that case, you just follow steps 1-5. In any case, try to consult the manual that came with your Audigy and see if it supports being hooked up the way you need, this might answer your question and make things easier for you.
