build 7264 and TrueHD audio problem

[VampyreGTX]

I've been using W7 since initial Beta on my HTPC with no issues until I went to RC 7100 build. Since then, I've had NO TrueHD sound output from the HTPC to my AVR. All other audio sources work (DTS-MA, DD, etc.) just not TrueHD. Info in both TMT and PDVD show the audio source as TrueHD; however, no sound is actually transmitted. Does anyone know if this is still an issue in the latest builds? Has anyone tried it? I rip my Blu-Rays onto my HTPC for ease of use (near one-click to play functionality) so they're all in Blu-Ray folder or .iso format with only the main video, HD Audio and main subtitles.

Well, I upgraded to build 7264 and no fix for the issue. Still no TrueHD sound from Blu-Ray's. Interesting. I may consider a clean install; however, has anyone else experienced this? I was wondering if it's just my system or an actual issue in W7.
