I've been trying to change my default audio format from 48kHz to 44,1kHz, but somehow the card won't allow me to do that (the drop down list is disabled). I googled a bit, but wasn't able to find any solution to the problem. Perhaps there is some tool to override default settings, or to change the sound card's .inf file?
I have Vista x64 Business with integrated AC'97 sound card.
Any help is appreciated.
