Sylvia,
I'm still experiencing the issue. I have tried all graphic drivers, BIOS versions, etc. available. I built my system 3/20/14, your new drivers are 3/11/14. I didn't even try the older drivers until I discovered the issue with HDMI audio and rolled them back. The problem still persists.
Gigabyte GA-H81M-HD3
Intel i3-4330 Haswell HD 4600
Philips 105S2 52"
There's another thread about this that I've been following the past day or so, and while some success has been reported, it's largely still an issue. Over at that thread a user has reported success with my particular board and an alpha version of Gigabyte BIOS. I don't know what's going to happen to all these other people who have different motherboards and still have this issue, but I will update as I can.
