I'm having problems getting surround sound to be passed through HDMI. My setup is I have the HDMI connected to my TV and then an optical cable from my TV to my amp. The amp is an old surround sound system that only takes coax/optical inputs. The XBMC version is 12.2 installed from the Team-XBMC PPA on XBMCbuntu updated to 13.04 though I've had the same problem with earlier versions of XBMCbuntu.
Surround sound is correctly passed through to the TV and then on to the amp when a DVD or Blu-Ray is played from my PS3. It also works if I ssh into the system running XBMC and use iecset to manually set the interface to none audio mode before playing a movie. I cannot get it to automatically change to data mode though. I've tried making several EDID overrides that append DTS and AC3 to the capabilities reported by the TV as well as the speaker layout without success.
I've made a debug log which can be found at http://xbmclogs.com/show.php?id=46413
Audio is configured in XBMC as follows:
Audio Output - HDMI
Speaker Config - 5.1
Boost on downmix - Yes
Output stereo to all - No
Dolby Digital - Yes
DTS - Yes
AAC - No
Multichannel LPCM - No
TrueHD - No
DTS-HD - No
Audio Output - HDA NVidia, HDMI
Passthrough - HDA NVidia, HDMI
Any suggestions would be appreciated.
