OpenELEC Testbuilds for RaspberryPi (Kodi 17.0)

I have found that non DTS or DD files will play fine as there is no "switch" to the DTS or DD needed.


If I play any material with DTS or DD sound I need to do the above if I use Kodi 17 but not any other.

Hope the above helps Smile

It sounds like you got yourself HDMI audio extractor. What type is it?

I have an old non HDMI (back from DVD days) 7.1 high current amp and I had to get one of those HDMI extractors. I bought no name true matrix 2x4 HDMI switch with stereo line out (used for headphone amp) and optical SPDIF audio out to my old receiver. Typically those extractors have 3 settings - 2Ch LPCM, SPDIF (DD, DTS over optical, coax) and pass through to TV. The selector switch or something similar supposed to pass the info to player (Raspberry Pi) to configure the sound properly over HDMI port. Mine is automatic detecting what is connected but it has a button on remote control to cycle through all 3 modes. On occasion (I don't think it's every time) I get the same issue as you described - no sound with DD/DTS. Anything that initialize the player will bring the sound back - "y" on the keyboard and select the player again, force new refresh rate ex. 24Hz from 23.97, disable pass through, or mode change on audio extractor. It's not a major issue but it could be related to the extractor switching or refreshing tags on signal delay or something similar.

The sound quality from my extractor is very good. No distortion or any digital noise from analog line our or optical port compared to Raspberry Pi internal stereo line out jack.

I'm thinking of getting one of those extractors with analog 7.1 LPCM RCA analog out. The similar unit with 4 x 3.5mm jacks analog out burned out when connected to my Epson projector. I had to return it for refund.
