Is this card being actively maintained? I've seen several reports of problems with this card (occasional metallic sound when recording, SPDIF passthrough not working on some receivers, etc.) but haven't seen any responses about possible solutions.
I wish I could volunteer to improve the driver for this card, but I think my technical skills to be able to do so are lacking :( I personally replaced my cs46xx-based card with a SoundBlaster Live! 5.1 because of the problems with the cs46xx driver.
