HP Pavilion dv7-6153nr Entertainment Notebook PC - just received an update for windows 7 last night, watched several movies, then restarted the computer . There isn't any sound.
When I ran the trouble shooting it gave me a message that "ATI High Definition Audio Device says "not plugged in" and that Windows can't verify the digital signature for the drivers required for the device.
I checked each driver to be sure they were updated. Checked the PORTS. Even did a system restore. No avail.
ll drivers are updated according the system. Any thoughts?
