For some reason after I installed the newest driver when I enable Dolby Pro Logic IIx, Dolby Headphone or Dolby Virtual speaker nothing happens and it just stays in stereo mode without decoding anything. I tried uninstalling and reinstalling new and old drivers but it doesn't change a thing. Does anyone have this problem?
u need to select speaker channel as well, however dolby headphone is designed for headphones... and dolby vitual speaker is made for anything except under 5.1
both of these DSP requires dolby pro logic to upmix it into 5.1 b4 being decoded into these effects.
