If you can't bitstream DTS-HD MA can PowerDVD send it via PCM?

I have PowerDVD 18 and a Windows 7 computer with a Core I3 and H55 processor. At present, I have not found a Display driver that will send DTA-HD MA or Dolby TrueHD. PowerDVD will only allow me to bitstream DTS or Dolby Digital. The High Definition choice disappears when I play a bluray. But it does PCM and all 7.1 speaker lights come on on my Yamaha Adventage 2000. But is it sending DTS-HD MA?

To have the DTS surround sound, either your audio receivers have to decode the DTS audio, or powerdvd has to decode the DTS audio.

If your audio recevier is not compatible with the DTS-HD-MA bitstream, there will be no sound if powerdvd did not decode the DTS-HD-MA audio for you when playing movies.

So, if you did hear the surround sound normally with all your multi-speakers while playing DTS-HD-MA audio, it means the DTS audio had been decoded as PCM by powerdvd already.

My receiver is capable of processing DTS-HD MA. PowerDVD does bitstream DTS which is inside the DTS-HD-MA. However it will not bitstream DTS-HD MA because the graphics processor in my computer can not send it. So when it decodes sends the uncompressed audio via PCM is it DTS or DTS-HD MA?

Theorectically, you should have DTS-HD-MA in -> Linear PCM decoded audio (from DTS-HD-MA) out to your 5.1 or 7.1 speakers setup.

Set the HDMI audio output mode as "PCM decoded" in powerdvd audio settings to have powerdvd decode your HD audio anyway.
Play your DTS-HD-MA encoded movie, and right click on the playback screen to select the "Show Information" option.
It will show the audio as DTS-HD Master, and output as LPCM on the "Show Information" OSD.
