Audio Quit on P40 Yoga

2017-10-22, 22:31 PM

Hi All,


I have a Lenovo ThinkPad P40 Yoga laptop running Windows 7 64bit that is about 1.5yrs old.  Today I was playing music on the system, and when I unplugged the power cord the audio output stopped and has not returned.  I tried plugging the computer back in, restarting the computer, updating the audio driver, and disabling/enabling the driver with no luck.  This was all done to the Conexant SmartAudio HD driver.  I honestly don't know if this has always been the default driver or not - never paid any attention to it.  The problem applies to both the internal speakers and the headphone output.  Even "testing" the device via the Properties option in the Device Manager yields no output.  Any help or suggestions would be greatly appreciated.
