Thank you so much for the suggestion. I did install it, but still the same problem.
I fear that maybe somehow the fluid from the soft drink may have either shorted out the speakers caused some kid of problem. I don't see anywhere where the sound comes out of the computer, no sound grate or anything, and it was a very small amount of fluid and just on top of the close computer. I suppose some may have gotten on the bottom. I am not sure. do you know where the speakers are in the Envy laptop?
The audio driver seems to be working correctly. I do get sound out of the Head phones, and out of the HDMI.
Thanks again,
