How to passthrough DTS/DD/PCM through the HDMI

[alejandrovk]

Hi there again,

I've connected my RPi to my AV and this one to my TV. While image and sound are excellent, I can only get Dolby Digital from the RPi to my AV....is this normal? I tried some movies that I know they have DTS and still getting DD all the time...any clues?

Regards,
Alex
