That is what I am worried about. I am willing to believe that direct show uses the acm drivers to decode the audio. I have not found anything to prove that yet but it is my gut feeling.
Well, there's dlls/quartz/acmwrapper.c. That won't necessarily be used depending on which other filters are installed on a specific setup, but I don't think there's any guarantee that it won't.
