I´m using the last Kodi/OSMC version for Raspberry Pi B+ and I´ve been testing the new feature that allows to get surround sound through HDMI (Support 8 channel DTS HD audio decoding) and I have a little question. I´m using wireless surround headphones (connected to the TV via optical toslink cable) that has lights to indicate the kind of surround playing (DTS, Dolby…). When I use mi Hifiberry Digi+ soundcard (connecting the toslink directly to it instead of the TV) this lights are on when playing 5.1, but with HDMI passthrough they do nothing. I think I get the same sound quality with both methods, but I would like to know if it´s normal that my headphones are´nt detecting the sound type or I should setup something.
Thanks a lot and best regards!
