Hi guys
I have a strange problem that I don't know how to fix.
A little of the story telling first... I'm updating AVStream driver that worked
perfectly under XP, but it fails under Win 7 32bit (vista not tested).
The driver copies buffers manually as the the card has a hardware bug and it
needs a specific copy protocol for it to
work... so everything is manually copied in DPC.
Now the symptoms of the problem is that I don't receive any stream pointers for
output buffers...
I get them for inputs, but the sound still doesn't come through.
After some debugging I've noticed in WindDbg that I get a strange warning:
---------------------------------------------------------------------------------------------------
Launch of AudioDG.EXE as a protected process failed with
STATUS_INVALID_IMAGE_HASH
This usually means that there is a problem with PEAUTH, because an unexpected
DLL was added to the audiodg.exe process
To find the offending binary, please do the following from an *elevated
window*:
1. \\showtime\public\pmp\tools\MSInternal\ConfigKeys\EnablePEAuthLogging.reg
2. Reboot the machine
3. \\showtime\public\pmp\tools\MSInternal\PEBinCheck\PEBinCheck.cmd
The output file on the screen will contain the offending binary.
To get the build to boot, audiodg is being restarted outside of the protected
environment, audio will continue to function, but playback of protected
content will be disabled
For more information, please see:

---------------------------------------------------------------------------------------------------
Normally I get this the first time I press start on any audio player.
Then DPC starts doing it's thing, but as there is no data nothing happens.
Now the thing is even more drastic that if you press stop or even close the
application, the stop command wont be send to
the driver, so the only option to stop it is to restart the machine.
I've rechecked if the Audiodg.exe files are corrupted on the machine...
compared to notebook running also running Win 7 32bit
and the files are identical... same size and same date of creation.
I've also checked event logs and there was a strange event for WMP that it
could not load DRM stuff, because debugger is
running... is this related to AudioDG.exe?
Has somebody already come around something like this or is there something I
can set (a flag or something) that would give me some more detail of what is
happening?
So that I can fix it...
Any help would be REALLY appreciated.
