I am using a Ouya to pass through 5.1 to a Bose v25 HTS. I supports almost all codecs; DD, DTS, Dolby True HD, LPCM 7.1(http://en.wikipedia.org/wiki/Bose_5.1_ho..._systems).*In Kodi I have HDMI AND 5.1 speaker configuration. Passthrough is enabled and have DTS decoding enabled. BTW, I do have the Ouya connected by HDMI 1.4 cable. I can not get any surround sound through my rear speaker, the effects sounds that normally come through them are now coming through the front speakers along with the other audio. I know 5.1 works because I can stream Netflix 5.1 with no problems at all. Hope you can help with this.
