Wing Commander CIC

I tried looking for a thread on configuring GOG's Dosbox- both games run pretty well and have joystick support on my setup (My old Microsoft Sidewinder, Windows 7, NVidia 8600 GT, Realtek High Def Audio). However, I can't get the authentic audio from either game- both games sound like they are being played through a low end midi card, as opposed to a high end Soundblaster. Any suggestions from anyone on how to fix this? A thread search didn't seem to help. Thanks!
