OK I had already posted in the Vista forums but didn't get a good answer. After I installed my Visiontek 4850 my sound stopped working. So I went into audio devices to re-enable my speakers, knowing it would default me into the HDMI set up that the cards have. Only to find that I have no other devices showing now, no speakers, no headphone, nothing. I have the box checked that says "show disabled devices" and "show disconnected devices." I had formally been using my onboard sound as well.
I couldn't find a spot in the CCC to disable it.
Also I am not knowledgeable enough to know what I should do if I tried to fix it in bios. If someone would want to walk me through it that would be great.
