Hello DugKing,
I asked one of our HDMI support engineers to review your post and here is something you should try:
1. Uninstall the Intel HD Audio driver from Device Manager and select checkbox to remove the driver files.
2. Uninstall the graphics driver.
3. Then re-install the latest graphics driver from https://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&DwnldID=22872. This will also reinstall the HD audio driver.
Let me know the results.
Regards,
Lois H.
