Hi Yannick, Thank you very much for your response. I finally got my 
sound input working by following the steps you outlined here. Have you 
had any other issues with your Mobo? I rma'd mine once due to losing my 
ethernet link between the mobo & modem. This happens very 
infrequently-maybe once a month. The only way I've found to correct this 
is to shutdown the computer, then remove power for about 1 minute, 
reapply power then restart computer. A simple reboot won't work. Asus 
tech support can't help-they suggested a possible bad solder point. That 
might seem reasonable once, but twice? I also got a new modem from 
Qwest. (my internet provider) Another issue I've had is the irqbalance 
causing loss of keyboard/mouse control. I've seen from several posts 
that this type of mobo seems to be re-occuring. Thanks again for your 
help. Dan
