Hello Geeks,

My Dual core PC running windows 7 with Mercury PIG31Z mainboard isn't giving out any sound. Will it be possible to attach an external USB sound device for both mic & speaker ?
It actually stopped sound after windows 7 installation. The Realtek AC97 driver installation is blocked by windows security.
This is bit urgent please advice.
