|I might have stumbled on a clue, nordeng92.|
It looks like that 'Media controller' thing that you found in SIW might be the audio adapter. It appears to be a 'HD" audio adapter. I'm not familiar with HD stuff.
What were the numbers and info that it showed for it?
(edit) It might be that it's installed ok, but maybe there is some setup that is necessary to get it working. I'm not really sure. This is out of the range of my experience.
Just a guess. How about checking your manual to see if it has anything to say about setting up your audio controls. That might be a problem since the switch was made from Vista to XP.
(edit again) Which SP level are you at? It 'might' be that it needs SP1, SP2 or SP3.
(edit even again) I'm still trying to get some information about this High Definition stuff.
I see things about a "microsoft UAA bus driver for high definition audio". I haven't been able to determine if it's required or not. Do you see it in the Device Manager? If it is needed, it can be found at http://forum.jayceooi.com/viewtopic...
I have found some people who fixed their HD sound problem by uninstalling their sound (Media) driver, installing the MS UAA driver and then reinstalling their audio (media) driver. But I still wonder if SP3 is all that is needed.
Check in the Bios to make sure that the OnBoard audio adapter is not disabled. I don't remember ever seeing a Bios with that option, but I guess there are some.
