Zotac Zbox ID82 HDMI Sound?

I am totally lost at this moment. I hear several people on this forum which have the same Zbox like me having HD audio over HDMI. I cant get this working.

If i check device manager i see 2 devices named:

High Definition Audio device (realtek/amd high definition audio for SPDIF or the green stereo plug)
Intel R Display Audio (HDMI)



If i check the sound device below Windows 7 Control Panel i see this



If i open the settings from the Intel R Display Audio and i check the codecs there are no HD audio codecs listed.



If i check the setting for SPDIF i see HD audio codecs (DTS, Dolby Digital, WMA Pro Audio)



The only thing i have different with the others users is that i do not use any reciever between my Zbox and TV.

I have my Zbox directly connected through HDMI to my Sony KDL-26S3000 (yes i know its an old Sony TV).

So why the others have/can bitstream HD Audio over HDMI? Even zotac saying the HDMI supports HD audio. I readed the wiki, but thats all about the realtek drivers and settings. The realtek drivers only work for the SPDIF and green stereo plug port, not the HDMI port which use Intel R Display Audio.

I am confused
