Bitstream audio not working properly

[Dennis99]

I have the following setup:

- Receiver AVC Onkyo TX-SR309
- AMD Radeon 6450 -> connected with HDMI to Onkyo
- Windows 7 32bit
- Shark007 Codec pack

Spend a zillion hours to get bitstreaming working properly, problem is:

Dolby Digital 5.1 -> works
DTS -> works
TrueHD -> no
DTS-HD -> no

So everything higher than DTS is not working, FFDSHOW audio icon says: "Bitstream HDMI audo TrueHD" but screen stays black and no sound, if i disable the TrueHD decoder in FFDSHOW the movie plays correct with the dolby digital 5.1 track included in the MKV.

In properties of sound in Win7 I have AMD HDMI selected with 2 channels, on the tab supported formats everything is ok.

I have tried every possible combination in shark007 codec pack but it has never worked.

A donation is on the way for the person who can fix this

did you install an audio driver separately from the graphics driver?
what version of graphics driver did you install?

I installed Catalyst 12.4 yesterday with the included AMD HDMI audio driver, the version of the AMD audio driver was februari 2012 I think, it didn't work after that. I tried today the latest Realtek AMD HDMI driver R.2.67.It didn't help

I have found on the internet a solution to override the EDID. I will try this tonight. Do you know this solution ?

be sure to uninstall the realtek driver.

For Control Panel | Sound, you say "on the tab supported formats everything is ok"
To delve further - you see the HD audio formats here?


Also, for testing, try this
press [Reset All] and then on the Audio TAB, select TrueHD/DTS HD-MA
test with no other changes

Are you sure your testfile contains HD audio?
use the button on the Misc TAB to [Analyze a media file] to know

Solved after months...

If you have a similar setup as mine, the problem lies not in codec packs but in communications between AMD videocard (AMD HDMI AUDIO) + AVC receiver + TV

You have to update youre monitor INFO file for the correct EDID (to override it), download the file here:

in the list pick the right one or a similar setup, and follow the instructions for installing (really simple) after that use reset all in Shark007 pack and choose bitstream audio. thats all, and it works !!

hope I help someone with this
