I have a customer that wants to process 7.1 sound but to a new 2.0 device
that is using Microsoft standard drivers i.e. no driver package.
They started creating an APO (SFX). I have helped them modify it so it can
do surround virtualization and it now can accept 7.1 in and send 2.0 out.
No problem.
The problem is legacy applications that use the mix format or look at the
device endpoint channel count. The question is if they want the big
solution (handling new and legacy applications) what is the best way to go?
Do they have to write their own driver for the product?
