Protected WMA music and Daniel K Driver

Question

I have been using Daniel K. drivers for my Audigy 2 ZS, X-FI Fatality and even my Audigy LS Windows XP and Vista. These drivers have exceeded my expectations their performance as always. Here is my issue that I have solved and I hope it helps others.
First, I bought nearly 00 .wma songs purchased from MSN Music in the last four years. I have played those songs through many formats, dri've partitionings, operating system changes, etc. I have went from XP, to Vista and now to Windows 7. Originally I used the Audigy LS with standard drivers from Creative and everything played fine. ? After formatting I would have to reauthorize my computer to play the songs, othewise I would get an error. Once the machine was authorized the songs would play fine. Now I use an Audigy 2 ZS, and the card worked well with XP and I authorized songs the same way to continue playing them. Using Vista though, I started using Daniel K.'s drivers for my system. The songs would no longer play, and I could not figure out why.
MSN tech support is awful and they gave me about fifteen knowledge base articles and finally said, "We will refund you for the songs you have bought. We have no solution for you."? Well I am glad they game me back money, but I still believe the songs could be played. After reading many many websites Here is what I have found:
These are the errors I received in XP and Vista:
error C00DB?C00D759: The policies that the Input Trust Authority requires to be
enforced are unsupported by the outputs.
And here is a compilation of the solution I found:
This is quoted to reflect the words of the original author ?
" The crux of the problem is that in my computer the DRM subsystem does not
trust the audio devices so it refuses to play protected content. It took me
a while to find the origin of the mistrust. In first place my sound drivers
were signed by microsoft nonetheless! so that should take care of that issue
no?
Wrong, it turns out that most important than having signed drivers is to
have the Operating System actually enforcing that! If the OS does not force
the audio drivers to be signed the DRM system will not play protected music
(even though your drivers are signed).
So lo and behold, my windows vista was shipped from the factory with the
signing checking disable. I guess that the reason is that most of the drivers
out there are still unsigned (because of the recent release) so the OEMs
prefer to disable the checking to make sure that a lot of old hardware still
works.
The registry entry that controls wheter or not windows vista enforces signed
audio drivers is in the following path (use regedit to examine/change it).
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Curr entVersion\Audio
And the entry is called
DisableProtectedAudioDG? (((<---------The key may be somwhere else in the registry, just search for DisableProtectedAudioDG---->))))))
When it is set to , the system does not check for signed drivers and the
protected content refuses to play.
So I only changed the value to 0, and restarted windows, now Vista does
enforce the protected audio and my protected music plays !!! (my normal music
also plays).
Be careful though, if your audio drivers are not signed, then, changing this
value to 0 will probably disable your music playback (not 00%).
So if your problem is that you don't get music at all, then try setting that
to , but if your problem is like mine (no protected music and you do have
signed drivers) then set the value to 0.
I hope this information is useful to any of you."

+ Hi,
I've also used some of daniel_k's driver pack. For the DisableProtectedAudioDG entry that you mentioned, I've found that it is added in driver pack where he did some modification to the original driver. My guess is the modification made the driver unsigned and so this entry is required (daniel, please correct me if I wrong)
