The answer to 3 and 4 is no. Just like the readme says, "LFX and GFX
APOs operate on a single input or output stream. They cannot be used in
"full-duplex" mode to process both input and output data." That's not
the intended use of this feature.

I don't know the answers to your other questions.

Subject: [wdmaudiodev] Vista APOs

Hello guys, 

I am trying to build Vista APOs from WINDDK 5112 samples. As is
documented, I followed the instruction " ReadMeToBuildAndInstall.txt"
from Sysfx directory, but couldn't get the right answer. 

These are my questions. 

1. Below are the instructions from the text file. Is it all true?
Because some are ambiguous for me. Could some one verify it?

2. assume, after setting all the path and copied all the data to the
proper path. How can I build it? What's the build command? Same as DDK ?
such as >build -ceZ ( or build -ceF )... 

3. Is this able to capture play out and record in stream both? Because I
want to capture both streams at the same time and process some data and
put it back to stream. 

4. If 3 isn't working, How can I capture the both stream? ( because I
saw this sentence in the attached sysfx.doc 

"LFX and GFX APOs operate on a single input or output stream. They
cannot be used in "full-duplex" mode to process both input and output
data"

5. Somehow if we can make a channel between play-out and record-in, how
much of system delay would be, because I want to do some DSP processing
which means the system delay is very important for me? 

Thank you for patience.
