Hi. This might be irrelevant or wrong, but I recall reading that as part of digital rights management (DRM) enforcement Microsoft makes it impossible to access audio from an output e.g. to route it to an input, except in a suitably signed driver. I'd be interested to know if I'm wrong here. M

Subject: [wdmaudiodev] Solution for MSVAD loopback interface

I am having trouble sending the data from the output pins into the input pins. I want to be able to capture system sounds using MSVAD as the capture source. I've tried using rtlcopymemory to send the buffer from copyto to copyfrom, but I just got silence. Has anyone implemented MSVAD in this fasion? What are the changes that need to be made?
