First time post on this forum. Driver / APO development is not my usual 
playground (hence feel free to elaborate and bare in mind I might not use the 
right terminology) but I have a question for the experts in this field.
Browsing the archive a bit I see that the one to one association between APO 
loaded on a device is there to stay. What is less clear for me is whether 
different "logical" devices (if such things exist) can be created on a unique 
piece of hardware (with possibly different APOs associated with each). 
To provide a bit of context to the request (which may help provide solutions 
entirely different than the proposal above), the ultimate goal would be to 
allow a microphone device to be used for VOIP solution with appropriate 
parameterization and processing, as well as for speech recognition purposes 
(with different parameterization and processing), without forcing user to 
change parameterization for one use or another.
If at all possible, a clean solution is preferred but for prototype uses I 
could consider hacked solutions as well.
