[robo989]

Hey, I do have a problem with AE as well.

I own an Intel Core i3 with an H55M-Mainboard. Buy a H55M they said ... it has native bitstream support for HDAudio they said....

Well everything is working nearly fine. MP3 and AC3/DTS Sound is working fine - AE detects the HDMI and the Receiver correctly.
What does not work are the HD Formats DTS HD Master / True HD

here are some additional Infos:

Let me know if you need more infos

Last but not least: Awesome work! Thank you! Where's your 'donate' Button?

Not sure who told you any of that, the only way of getting DTSMA decoded is through an nVidia graphics chipset bitstreamed to receiver for decoding, currently, on Linux at least.
