I have a raspberry pi running openElec (latest version) which is connected to my Sony STR-DH520 AV receiver that is capable of decoding all the latest audio formats. When playing a file with DTS-HD or DTS audio my receiver only shows LPCM (which to my understanding means that the audio is being decoded before being sent to the receiver). I've compared the sound of a Blu-Ray with a Blu-Ray rip of the same film and can confirm that I'm not receiving true surround sound from the raspberry pi.
In the Audio config I have:
Audio Output = HDMI
Speaker configuration = 5.1
Boost volume level on down mix = Yes
Output stereo to all speakers = No
Dual audio output = No
Boost centre channel when downmixing = Yes
Dolby Digital (AC3) capable receiver = Yes
DTS capable receiver = Yes
Any thoughts on how I can force hdmi audio passthrough from the pi to my receiver? Thanks in advance.
