I have had to do the same thing.. along with boost the color level to
about 80%, and the brightness to 60%, on every channel. Also, I don't know
if it's more the card or the software, but I found the default sound
configuration to be very low quality (you could hear the compression), so
I am now running with uncompressed audio.

Did you set the default mixer volume level in the setup?

Did you mute your line-in?
