Disabling monitor speakers with HDMI connection

[beboppin]

I just received a 24-inch HP monitor and am dual-screening with another monitor. In order to be able to use both, I connect the HP using HDMI and the other using VGA. Unfortunately, I am getting audio only from the 24-inch monitor as opposed to my regular speakers, which are plugged into a dock, into which my HP notebook is connected. I tried to disable the HDMI monitor speakers through control panel but sound still does not come from the speakers. Please let me know if there is a simple solution to this and that I am just being an idiot (I sure hope so...).

I am using Vista 64-bit if that is relevant at all.

Thank you!

Did you ever figure this out?
