I need a new soundcard...

The new computer we got for audio editing at the radio station has a sound card that is incompatible with Audacity. It's a Sigma Tek and does not allow for "stereo Mix" recording (the only sources you can choose are mic, rear mic and line in). Is it difficult to replace a sound card? Anyone know if any other sound cards have this problem?

Haha I think I have one of your shirts, from Scott from Secret Santa. It's not difficult at all to replace a soundcard. You just unscrew the computer case, pop the card out of the mobo, and install the new one. And if you're looking for recommendations the Chaintech AV-710 comes HIGHLY recommended by audiophiles and the like; and it's only $30 or so.
