Hi, I would like to pass the sAPO DTM test with the PUMA (Protected User Mode Audio) Security enabled. To have audiodg to load my APO, this APO need to be PE certified as I red here : ( //www.freelists.org/post/wdmaudiodev/DTM-tests-for-APOs-in-VIst,1). For now my sAPO passes the DTM (now HCK) test with DisableProtectedAudioDG. To be certain that my sAPO is fully functional I would like to pass the DTM test with the Protected Environment. How can I do? Thanks,
