Hi,
I had the same issue at hand a little while ago and i wrote to a company who
just writes DirectShow filters, they responded by sayin that this cannot be
done using DirectShow filters and then i found out i need to write a upper
filter for audio.sys. I am not pursuing this project anymore but just
letting u know of my findings which will speed up ur decision making.
Let me know if u need further help.
btw i m still interested in coding it , if u agree we can do it together .
Regards
Raza
