Install the MS UAA driver BEFORE your laptop's audio drivers? If not, no sound.
Example install order is noted at http://forums.cnet.com/5208-7587_102-0.html?hhTest=1&forumID=69&threadID=271360&messageID=2699006#2699006
Notice the line "Harold 3"...
Hello, I'm running windowsXp on an ibm netvista 8303-hue. I recently installed linux on a different partition and my sound works fine there. It worked in windows before the installation of linux. Now I have no sound in XP. Except whats coming out of my internal speaker. I know i have the right drivers installed. This one has me stumped. Any help would be greatly appreciated. -Thanks
