New kid here, who posted this first in the windows 8 forum, but probably should've put it here. Oops.
Pulled my graphics card as a test because it may have been causing problems, but that isn't for this post. My problem is a "disappearing" intel hdmi audio driver. My monitor is connected with HDMI, so once I pulled the graphics card I installed the "Intel Display Audio HDMI1" driver. Worked fine, EXCEPT every time the computer sleeps the driver disappears and I must reinstall. I've now set the computer not to sleep. Win 8.1 64 bit, I7, Intel 4000 onboard graphics. Thanks, Mike
