Bryan,
I'm having this same issue with my computer. I can't play normal media files on my computer because they won't go through the Krystal card, and the option to choose another sound card is grayed out.
How can I make the Krystal card the primary sound card for all audio media files, such as MP3s in Windows Media Player or Winamp? I get error messages whenever I try to play files through those programs.
I'm running ME5.5 on a P4 with the Krystal DSP 1200 card version D.
Thanks,
Laura
