Sytem details: H55M-UD2H, rev1.0, F10 firmware, Intel i5-660 using on-board video, 8 gigs ram DDR3-1333, Sony Optiarc 5600s bluray drive, Arcsoft Total Media Theater 3 Platinum, Samsung TV LN46C650, same HDMI cable as has worked on previous build. All chipset and audio drivers provided by Gigabye updated as of today.
HDMI audio works by choosing "Samsung" as my audio output device in Win 7 (pro-64bit). The regular HDMI audio device appears in the sound devices list, but cannot be enabled because win7 says the device is "not plugged in" - but this is the on-board HDMI device. Video over HDMI is perfect.
DVDs and all other media play fine except BluRay.
When I play a bluray, the sound works in the menu, but when I start the movie, I get a very loud high pitched beep for a second or two then just very loud static thereafter. Is this a HDCP issue? If so, how do I convince the system that it is HDCP compliant? Or is this motherboard NOT HDCP compliant?
This is a new build using this new motherboard. The bluray drive and decoding software were used on my previous build without problems so I know they work. Software patches and firmware updates have all been applied. I have NOT tried using other audio output methods as I don't have cables, but I want HDMI to work in any case.
