OK so my computer is a hp pavilion a1230n and when i upgraded it to windows vista, the sound card suddenly stopped working! i looked around, and my sound card doesn't seem to have any drivers for windows vista. i looked at the model, and i think this is it :integrated ati radeon xpress 200. my device manager says no device has been installed, but it's there because it was working with windows xp. i was wondering if there's any way i could update it or something. please comment! help would be much apreaciated (couldn't remember how to spell lol)

Hi armageddan and welcome to the forums

According to the HP website, your sound/audio solution is of the AC'97 type. You can obtain generic drivers for this from the hardware manufacturers - in this case it will probably be Realtek (link given below). To verify that this is the case, you will need to look in 'Device Manager'. Click the start orb and type 'Device Manager' into the search box and press enter/return. Click to expand the category 'Sound, video and game controllers' as shown below (this is from my system). If it shows as being a Realtek device then follow the link below, otherwise reply with this information so that we can locate a suitable driver for you.

Realtek

it says it's an ads integrated hdtv pci, i don't think it's realtek i'm not sure here's a pic

What you are looking at is a HD video capture card, not the on board sound card.
