I have an external sound card on Windows 7 32 bit installed on a HP notebook from 2008. The initial work (also) using the latest drivers of the Creative website very well. But unfortunately the entrance is only 1 channel / mono and has a bad signal to noise ratio, on my system about 50 db. At first I thought an error and did so my system is reset and the card installed, with no change. The support from Creative announced then on request, after 4 days, with that that would be so. So very useful to hear, but if you like I want to record in good quality, unfortunately unusable.
