In 05/06, I posted a succesfully play with DTS-HD and TrueHD with your help. I was very very happy!
But - without changes - saturday, the HD sound didn't work :-(
Checking the windows HDMI properties, the SO support for HD audio WAS GONE (see image). Before, it displayed also "DTS-HD" and "TrueHD" on list
None change was done to stop working.
My receiver Onkyo is DTS-HD and TrueHD compatible. I tried conect in other onkyo HDMI port, but the problem remains. I tested a Samsung BD player and the HD sound was ok. No problem with Onkyo
Help me again. I very frustrated!
UPDATE: My motherboard is a Intel dh57jg (supports HD bitstream)
In other forum, I found the solution.
For Intel mobos, it's necessary "Intel Manageability Engine" (IME) installed for HD Audio be enabled.
I installed it ansd everything works fine now.
I'm with a very strange problem here.
I have a HTPC with bitstreaming DTS-HD, Dolby TrueHD...
My motherboard is Intel DH57JG connected by HDMI 1.4 in a Receiver Onkyo HT-S380 (Suports HD audio)
Software: Win7, MediaPortal 1.1.3, Codec SAF 5 or 6
When I install a fresh windows with drivers, I have all formats enabled in HDMI properties (see image 1).
But during configuration, something (not yet identified) kills the HD audio formats (see image 2). Only DTS and Dolby remains...
I reinstalled drivers (originals and recents), codecs, firmware etc. Nothing solves. Only I get them again, if I format and reinstall windows, but the problem repeats with configuration. It's a circle of terror!
I also tried to create a mirror (using Norton Ghost) of a "enabled" situation, but when I restored it (look, from a 'good' situation), HD audio DON'T appears too. It's very strange!
Yes, I'm sure.
The recent H57 chipset is HD audio enabled (DTS-HD and Dolby True-HD)
By the way, when I install a fresh windows with drivers, all audio formats are there (see image).
Something in configuration 'kills' them
"HD Audio and gigabit Ethernet are native to the chipset as well. The DH57JG enables comprehensive 10-channel sound (7.1-channel + two independent multi-streaming channels). Moreover, it’s able to bitstream Dolby TrueHD and DTS-HD Master Audio over HDMI, making the board a shoo-in for home theater PC designs with Blu-ray drives. Though most mini-ITX builds won’t warrant discrete graphics, the DH57JG does sport a 16-lane PCI Express 2.0 expansion slot able to house any add-in board you choose to deploy, enclosure permitting."
