Mike, While the Windows XP OS will not have a problem with a second sound card, the same cannot be said for all sound application programs.
I had a problem with DXLab's WinWarbler when using a second sound card. The problem is that the D44 input and output channels are not equal. Many programs that use sound cards expect the input and output ItemIndex number to be the same. If they are not, then problems can occur. Below is an example of the problem on my system. These are the sound devices listed by a program called MixerInfo16. Wave-in Devices' list: Microsoft Sound Mapper SB Audigy Audio [FEE0] M-Audio Delta 44 Multi M-Audio Delta 44 1/2 M-Audio Delta 44 3/4 M-Audio Delta 44 Mon. Mixer Santa Cruz(tm) (Note: ItemIndex 5) Wave-out Devices' list: Microsoft Sound SB Audigy Audio [FEE0] M-Audio Delta 44 Multi M-Audio Delta 44 1/2 M-Audio Delta 44 3/4 Santa Cruz(tm) (Note ItemIndex 4) Note the Santa Cruz ItemIndex numbers. They are not equal because the D44 has 4 in devices and 3 out devices. Any devices after the D44 will have different ItemIndex numbers for their input and output devices. Programs that use a separate setting for the In device and the Out device will work correctly. Unfortunately, if a program expects the ItemIndex to be equal there appears to be no way around the problem (that I know of, Help anyone!) except to define the device as the default device (ItemIndex 0) which will move it up the list so that it occurs before the D-44 devices. I haven't figured out what Windows XP uses to determine the order, but it does not appear to be based on device installation order. You can force a temporary order change while installing a driver, but on reboot the order will be as determined by Windows XP. 73, Bill NJ1H -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Eric Wachsmann - FlexRadio Sent: Monday, January 16, 2006 4:10 PM To: 'Mike Monnier'; [email protected] Subject: Re: [Flexradio] Second Sound Card Mike, There is no reason that you can't install the Turtle Beach card along with the Delta 44 in your Optiplex machine. Windows handles multiple soundcards fairly well in my experience. I have had as many as 5 devices attached concurrently without a problem (besides confusion about what is connected to each!). I agree that the archive link is not as easy to find as we'd like it to be. Since we are using the mailman software to run the reflector, I am not sure how easy it would be to modify the digest links. If anyone has experience with this, please let me know privately. In the meantime, we will add a link to our website (not sure where just yet). Thanks for the feedback.
