Hey!
First things first, I'm running an Aspire V3-772g laptop.
Microsoft High Definition Audio Driver
After the recent Windows 10 update, I was having issues getting past the lock screen (took AGES to get to the point where I could input my password) and it had been a while, so I reformatted ('reset my PC' deleting all files) - this actually didn't solve my problem, so I used Rufus with a Windows 10 iso from Microsoft to delete all partitions and REALLY start fresh. Ever since, the laptop is running like a dream--in all but one respect.

Dec 29, 2011 NEW: How to fix Audio Device On High Definition Audio Bus Drivers problem, This isn't a fake vi.
It seems like no matter WHAT I do, I CANNOT get my HDMI audio / TV to appear as an option in Playback Devices (yes, disabled devices is ticked). Looking in Device Manager, the High Definition Audio Device has an exclamation mark is throwing a code 10 - device unable to start. I've tried uninstalling it, tried installing all drivers from Intel's V3-772g page including chipset, updated my graphics driver / Realtek / Intel HD audio drivers... and yet, nothing. Ran /sfc, ran /chkdsk, nothing.
I read something that led me to believe .NET framework might be part of the issue--and I did actually have quite a bit of difficulty getting 3.5 installed / functional, but I finally did...... and still, nothing!!
I'm seriously losing my mind. I'm having to run my surround sound through an auxiliary cable into the laptop, which is just sacrilege and a fraction of the quality.

If there is ANYTHING, ANYONE can suggest beyond the above, please do!!
