Hi Sajid,
To answer you questions, see below:

The "Audio Device Manager" is just a generic name for the code that sits
between applications using the wave API and audio device drivers. The "audio
device manager" manages audio devices (big surprise), and includes the
kernel mixer, audio compression manager, and wave mapper, and also handles
various aspects of security, interprocess communication, application
callbacks, etc.
> 2. What does the "Audio compression Manager" do ?
The "Audio Compression Manager" is documented in PB help. Using installable
codec modules, it allows recording and playing back compressed audio formats
such as GSM6.10 in a way that makes the encoding/decoding transparent to
both the application and device driver.
There is a topic in Help titled "Audio Compression Manager". Here's the
link to it on MSDN
http://msdn.microsoft.com/library/en-us/wcemultimedia5/html/wce50conAudioCompressionManager.asp?frame=true
There's also a little bit more overview content for the ACM mixed in with
the audio driver documentation around about here:
