I have a dv7-7270ca notebook and since a restart due to windows 8 updates I now have a red x on the speaker icon. I installed the HP driver for this model but it has an error in device manager that says:
Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. (Code 52)
Any help with fixing this would be greatly appreciated. I did run an audio test using the shut down-F2 and passed and could hear the sounds in the test. Thank You!!
