Thanks in advance for the help! I have a Dell XPS 17 (L702x) laptop with an Nvidia GT 550m card. I have ripped some blu-ray discs to MKV with MakeMKV. I am now playing back the MKVs on my laptop with it hooked up to my system but I'm not getting HD sound. I have it set up like this:
Laptop -HDMI cable- Pioneer Elite VSX-94TXH AVR -HDMI cable- Sony HDTV
I can play back the files fine and watch them on my TV but no HD sound. I can get the AVR to display DTS (or Dobly Digital depending on the movie), "stereo", or PCM sound but no bitstream HD audio. I don't really care that it's bitstreamed per se but I don't think the PCM audio is decoded HD audio (LPCM). The files definitely have the HD audio tracks as part of the file, every program I use shows the lossless track is there.
I have tried play back via VLC, XMBC (with and without the HD bitstream patch) and Potplayer. I have installed FFD show and LAV Audio. Still can't get it to work. I must be missing something. Please let me know what I'm doing wrong.
