John:
I don't have an answer on how to get your sound card recognized
again. I got a late start today because I had 2 doctors appointments this
morning, no bad news, looks like back to work mid-March. The USA and U.K.
sites weren't available so I downloaded the updated beta drivers from the
Australian site. Currently I'm using the X-Fi driver 2.13.001 dated
12/28/2006, driver ID 6.0.1.1261. The updated Audigy 2zs driver that I
downloaded 2.12.001 dated 1/7/2007, driver ID 6.0.0.1241. I updated to the
new beta driver through device manager, after rebooting there were conflicts
with the Creative Audio Console and my sound wasn't right. I was lucky to be
able to roll-back to the X-Fi driver. Just a thought on my part is to scrap
the Creative beta drivers and use the X-Fi drivers until Creative
straightens out the mess. This is more of a headache than we had with
Creative drivers with x64. Have a great day.
