Hello, after completing the Automatic Updates the sound on Lenovo T61 XPSP3 "disappeared". The "Sounds and Audio Devices" show no audio device present. The Audio Device on High Definition Audio Bus has a Yellow "!". Tried the following: 1. installed KB888111 obtained from MS hotfix. 2. Tried to install the Soundmax audio driver package (7KA114WW) obtained from lenovo support website and got the following message: "Audio Driver Installation Failed" 3. After that Soundmax is not installed at all. I've checked different forums and web-sites and nothing worked. Installed Driver Detective which pushed the same 7KA114WW from Lenovo as solution for the Audio Device on High definition Bus. I can't backup the updates using System Restore (tried few different check points) as it is not find any changes. Any suggestions or help? Please, any ideas before restoring the system to the factory setiings?
