just did update the audio device now No audio output device

[johnp126]

installed...

not sure why. found a ms kb article did the download but it says does not apply to this system. i deleted the device and then the driver, added it again still same issue (briefly during the install the device came back). when it does not work in dev mgr you get a yellow ! point thru it. running x301 vista 64 latest lenovo patches installed and win up to date
