HP High Definition Audio Device Code 10 Error -- Causing HDMI Sound Problem

Hey guys, my laptop is an HP ENVY TouchSmart m7-j010dx Notebook PC, running Windows 8.1.

When I connect my laptop to my LG Smart TV through HDMI, I cant change the playback device to play the sound from the TV. The HDMI option does not appear in ¨Sound¨.

When I look in Device Manager, under Sound, video and game controllers; the High Definition Audio CODEC has an error which says (Device status):  

This device cannot start. (Code 10)

{Operation Failed}
The requested operation was unsuccessful.

I have tried reinstalling and updating the drivers, cleaning and defraging the registry, optimizations etc.

I followed steps from other posts with similar problem as mine and nothing seems to work, I do not want to reinstall my windows just for this! I am running out of options, I tried everything I could for the past week. I would really appreciate some expert advice.

Thanks!
