I'd install the motherboard chipset then the audio driver.
Hello.I am trying to upgrade a mx3560u for someone and after installing the Vista H P I can no longer here sound? I know the sound works I put in another hdd with xp and the sound worked. When I had the XP hdd installed it had the 8086 x 24c5 driver installed. Which I am pretty sure is AC'97. I tried installing the AC'97 for Vista off Cnet and a few other sites and it would get stuck 3/4 the way through and I would also get warning signs about an untrusted download or connection? When the Vista is installed all drives work except sound. The sound drive automatically installs Intel82801DB/DBM AC'97 driver but no sound.I troubleshoot and says all speakers and devices are working properly. Any help would be appreciated. Thanks
