Audio.script in Win 7 PE do not copy crucial files from installation source

Dear core developers,
Would somebody of Us tell Me, why audio.script, which is included inside The latest available and stable WIN7 PE download package do not copy crucial files from The installation source?
Why somebody of core developers make this kind of Winbuilder script, which do not work for users with basic computer knowledge?
It is very sad strategy and i would like to know its aim.
Here are The warnings. I have analysed resulted .wim file and really, files do not exists in Windows\system32

I use The Windows 7 SP0 as installation source, .iso image is mounted by using Imdisk virtual disk driver.
Is it because i did not extract The .iso image with Windows7 SP0 X86 to The separate folder?
I believe, that this non functioning audio.script will be repaired, because users who do not know Winbuilder so much do not have chance to repair this script.
I have tried to include The script, because i have thought, that script is excluded from The project by default.
But it did not help me.
Many thanks for Yours analysis and steps, which would make audio.script fully usable.
Thank You very much.
With kindness regards.

You already gave the answer:

I have analysed resulted .wim file and really, files do not exists in Windows\system32

which gives usual suspects:
- customized (none official) source [ a very usual suspect for a regular user)
- a weird or new wim mounting trouble

It is very sad strategy and i would like to know its aim.

It is very good strategy that serves well its purpose.
Windows7 have 6 editions, and also a SP1 , and also x86 - x64 ---> 6x2x2=24 ,
 don't expect every plugin to be tested with all 24 editions by any developer for Win7,
  in addition there are customized and sometimes ms updated sources,
   we do not have such a tech team around, all you have is pure hobby work which is developed by individuals.
    feedback by end users required, which as you already did, aim success.

With all different sources, a perfect work have been done by ChrisR and JFX with the available time they have,
 it is very normal small things happens time to time, especially with rare used plugins like Audio.

Also, extracting would give you ( Utis\Extract Wim Folders) better result to be sure nothing wrong on mounting wim,
 As you already know such option exists, Why did not you first try that option !! .
   It is really very sad not using all provided options, which would give better feedback on such topic.

Aside we do not know what source you are using, maybe a customized one,
 it is sad strategy to ask feedback without providing all information. (so far all we know you have a Win7SP0 source, god knows which editions, which architecture, or customized one....)

Anyway,
 On main plugin page of Win7 ,
  There is a button "List of Official Windows 7 ISO from Digital river"
    Where you will get official sources, which developers used on developing plugins.

And as one should already be aware, after Win7SP1 , plugin development more continued from Win7SP1 source,
 it is natural flow of life, as in all nt6x projects around, after latest, plugin development continues with latest.
  (Ex: Currently more development with Win81 source on different project)
    so I would advice you to download one of Win7SP1 sources to test with.....

Nothing I wrote above is anything special for a regular & carelful user.

Dear Lancelot,
I Am very sorry.
I did not realized that it is so complex and that there are so many variants of Windows 7 CDS. I AM deeply appreciating all developers about this project, but i have got sad mood.
So i will download official iso image from digital river. I have used official Windows 7 SP0 trial edition downloaded once a pony time from Microsoft WEB site. It is multi edition basede system, so user can choose The edition by specifiing The edition during installation.
So i will just try to download by using direct link from digital river.
ANd i Am very sorry to You and others. I will clean my bad results from The project folder and i will start completely from scratch.
Because MR Chris have made working Windows 8.1 with NVDA, my goal is to make functioning one for Windows 7.
