No HD Audio with New Build

post #1 of 8
Thread Starter 
I've been troubleshooting an issue with the build posted here http://www.avsforum.com/t/1487058/home-theater-makeover-build-replacing-many-components

It is very annoying because the sound device properties in Windows lists that it is compatible with DTS-MA and Dolby TrueHD. Using Arcsoft TMT 5 connected to the Yamaha RX-V775 I'm only getting Dolby Digital or DTS, no TrueHD or MA. I think I've ruled out the computer as the issue because I tried a Blu-ray player and it only did Dolby Digital even though I selected Dolby TrueHD. My guess is the rather dated Panasonic PT-AX100U (720p HDMI connection) causing trouble. I also tried turning off the projector and only connecting a VGA monitor, but still no HD audio even though that probably isn't the best test.

Any ideas on what to try next? I thought about grabbing a flat panel TV from another room and using it in place of the projector to see if that works. Or I could bring the AVR to my house and swap it with mine and test (we both have Yamaha AVRs).

Have you installed the intel management engine driver from motherboard install disc is tmt 5 set to hdmi in sound settings.
Also have you got the latest update for tmt 5 being such a new chipset cpu may require update for tmt 5.
As a side note have you set the hdmi settings in blu ray player to bitstream on hdmi and have you set yamaha to only pass video to screen.

Thanks for the suggestions. The version of TMT 5 that I'm using is the last one without Cinavia. Since the Blu-ray player didn't work either then I'm thinking the HTPC settings are fine, but I do need to double check the Blu-ray player settings. I'm going to have to make another troubleshooting trip to his theater. I may have to bring the HTPC and/or AVR back to my house to test in my system. Out of all the testing before delivery, the HD audio was the one thing I didn't think of checking.

After doing some research I see that the projector is HDMI version 1.2a. It wasn't until 1.3 that HD audio was supported. Need to try a DVI to HDMI converter or his other TV if it is HDMI 1.3.

If op is using an AVR, it doesn't matter what his TV supports. It only matters what his AVR supports.

I am using an AVR that supports everything (even 4k). But the sound playback device is registering as the projector.

The sound device name is not that accurate. It can be anything (your TV/PJ or AVR). On my laptop, it even shows up as an old AVR that I have already replaced. If the TrueHD and DTS-MA showed up in the supported formats, you are fine. The problem is probably at playback software side.

As for your BD player story, you should know most BD players default to NOT bitstream HD Audio at all. You will have to make configuration changes (typically turn off secondary audio) to make it bitstream.

After a couple hours on site troubleshooting I finally got it to bitstream HD audio. I took my laptop with an Nvidia 660M and a known working HDMI cable with DTS-HD MA and Dolby TrueHD known working test files. Plugged it in and it worked. Tried the same test files on the system and it still didn't work. I finally double checked the Intel Graphics Driver by manually selecting the HD 4600 Win7-x64 option, before I think I may have started with the one on the ASRock download page and then did an auto-detect on Intel's site yesterday and it found an update. With the manual download it said it was an older version even though it was the latest selected. Once I installed it the test files all played HD audio. I guess the ASRock driver wasn't for the HD 4600 on my i5 or something or had a bad audio portion included.

Now my next issue is that TMT 5.146 didn't play HD audio on either my laptop or the HTPC, but it does work fine on my own HTPC. My HTPC is a Sandy Bridge i5 so maybe there was a patch along the way for newer gpus. My laptop as mentioned is an Nvidia 660M and the other HTPC is a Haswell i5. I guess I need to try a new version of TMT, but I was hoping to not deal with Cinavia.
