Bro will the build you suggested be able to pass audio through hdmi to TV/receiver with blu-Ray drive?
No. You wont get sound from it if you wanna direct play it from disc.
To play back sound, such as DTSHD or Dolby TrueHD you will need a couple of things to work together in order to playback the sound.
*Reason, Bluray sound are encrypted in within the disc, and only a standalone player can decrypt it out. Normal Bluray Driver for PC do not have build in decrypt. Thus unable to play sound directly unless it is pass down to other external means.
1) GPU that has a HDMI sound pass thru
2) AVR with DTSHD or DTHD coder
3) AVR must have HDMI
4) A player such as XMBC
And lastly a few things you can choose from.
1) A EOL Asus HDAV 1.3 Sound card. This is the only soundcard in market and a surviving coy that has HDMI sound pass thru.
OR
2) You will need a external DAC that can pass thru the sound signal from the GPU to the speakers.
OR
3) Not directly playing from the disc, but to rip the entire bluray into the HDD. And playback from HDD.
OR
4) You can playback by using special license software such as Slysoft to decode the sound from the disc.
