Two sound cards supplying same output.... Possible?

I have an MSI P965 Platinum w/ onboard Realtek HD audio and a PCI SB Live 5.1. Is it possible for these devices to share all stereo output simultaneously? I can't seem to find any information pertaining to this specific scenario. I have a stereo splitter and understand that that will work, but I'm really trying to sync the line out on both cards. Can anyone help me?

You just want 1 line out from each card-or are you trying to get 5.1 sound out of each?


If you are just trying to get 2 identical stereo outputs, you can accomplish this in a couple of ways using the kX drivers (This does mean you would have to uninstall the Creative drivers). The latest version 3538M is available in this thread.

With the kX drivers you could send 2 identical stereo signals out of the SBLive, one out of Front Out, the other out of Rear Out.

You could also, by connecting the 2 cards via SPDIF cable, link them and send the output out of each card.

Thanks, although I don't usually use 3rd party drivers, that would do the trick. I'll take a closer look at that.

Hello to All,

Why two cards? Have you ever thought about gaming with the game sound being directed to your desktop speakers while your TeamSpeak sound is directed to your headset. Two applications working independent of each other to collectively maximize your gaming experience. On a second note if we stop to think of where technologies is heading, it is naive to think that while listening to music you would not want to communicate with your acquaintances via VOIP. You mean to tell me teenagers don't ever listen to the radio and talk on the phone at the same time. So I would ask the question, why do you not have two sound cards or more appropriately, why does Windows not support directing digital information to whatever output you want? I thought this was the reason for digital technology versus analog. Thoughts?
