I just upgraded to Vista SP2 on a HP Pavilion dv9700. I now have no audio device. I have a "Audio Device on High Definition Audio Bus" in Device Manager I have tried installing the 3 below drivers. None have worked.
Conexant High Definition SmartAudio 221 Version: 184.108.40.206
Conexant High Definition SmartAudio 221 Version: 220.127.116.11
High Definition Audio Device
I have uninstalled it rebooted and tried reinstalling it but it will not install just errors our with "Windows encountered a problem installing the driver software for your device" "This operation requires an interactive window station"
