I'm just digging in to the creation of a GFX APO, and I'm looking for a few debugging tips.I don't seem to see my OutputDebugString output in dbgview when my DLL is loaded into the audio engine service. I do see the messages when it gets loaded by Control Panel, but that's not the interesting case.How can I insert a new version while I'm debugging? Even if I disable the Windows Audio and Windows Audio Endpoint Builder services and disable my HDAUDIO device, my APO DLL remains loaded in one of the service host processes, and I can't copy a new version into place while it is loaded.Any debug hints from folks who have been in the trenches would be appreciated.
Well, for what it's worth, I can get the debug messages if I attach a debugger to the audiodg.exe process itself. I still don't understand why the messages don't appear in dbgview.
And the issue about not being able to update the DLL seems to have been a transient thing. As long as I stop the two services, I can replace the DLL just fine.
