Hello everyone. I have a problem with my Intel NUC HTPC that I'd really appreciate anyone being able to shed some light on. I'm using an Intel NUC D34010 (Intel i3 processor, Intel HD graphics 4400) HTPC connected over an HDMI cable to an Oppo BDP-103 BluRay player. The oppo then connects over HDMI to my TV panel and via RCA connectors to my power amplifiers to drive the speakers. I'm not using the Oppo to play BluRay disks, it's role is to decode the audio and pass the video signal out of the other HDMI port. I'm using XBMC 13.1 to playback content.
My problem: I get video, I can play DTS and Dolby Digital (AC-3) fine but I can't get HD audio to work.
The issue lies on the Intel NUC. If I look in the Supported Formats tab in the Sound control panel, under Encoded Formats I don't see any of the HD formats (DTS-HD, Dolby TrueHD) listed. I've:
Updated the drivers to the latest versions from the Intel web site - I definitely have the latest Intel graphics drivers, v10.18.10.3643
Updated the BIOS to the latest (0027)
Disabled the Realtek output and removed the driver, just in case that was interfering with the Intel HD Audio
Confirmed that I'm using an HDMI 1.4a cable between the NUC and the Oppo
Powered-up the Oppo before the NUC to see if the HDMI handshake was the issue
None of these make any difference, still no support for HD Audio
Any ideas? I'm running Windows 7 Home Premium 32bit - the fact that it's 32bit not 64bit, would that make any difference?
My thoughts are to try dual-boot with Xbmcbuntu (but I need a bigger SSD for that, so not a cheap/quick option) or maybe buy a Gefen HDMI Detective Plus in case it's a protected pathway / HDCP issue (but they're $80 and I'd rather rule everything else out first before doing that!).
Hi Dark, thanks for the reply. Yup, I have that installed. My understanding is that the Intel Management Engine is a necessary component to allow the protected pathway in HDCP to work. When I look under the Device Manager all devices are working properly and I see Intel (r) Management Engine Interface listed under System Devices.
