Audio problem on HDMI output on Asrock boards

[bgt]

I get no audio output through HDMI on the following boards:

H81M-ITX/HDS
B85M-ITX
Z87M Extr.4


Although they work through DVI you still need a convertor from DVI to HDMI if you only use HDMI-HDMI cables. For HTPC this is a nuissance.
The Asus H81T works ok through HDMI.

Did you enable HD Audio in BIOS? I don't remember the specific tab name, but make sure everything is clicked on.

DVI works ok so HD is on.
