Hello everybody,

I am trying to get DTS-HD audio playback working. I got bluray-images where my AV-receiver gets a DTS-96/24 stream via SPDIF (optical) and everything works just fine. If I however try to play a 96/24 FLAC DTS-stream, XBMC somehow only sends a stereo signal. In the settings, the DTS-capability and DD-capability of the receiver are switched on. I tried to mux the DTS-FLAC-audio to an mkv-videofile, but i didn't produce any difference, still just stereo playback.

On some sites, I read that spdif is not capable of playing DTS-HD material because of bandwidth limitations. But why does it work with non-compressed bluray-images?

My system is:
Acer Revo 3610 (alc662 chip) via toslink
Ubuntu 12.04.1 kernel 3.2.0-36-generic x86_64
XBMC 11.0 from pulse-eight
no pulseaudio, just alas

Thanks in advance,
peter

Toslink wont do hd audio.

The best toslink will do its the dts core.

To do dts-hd you HAVE to use a hdmi connection.

Thats what I read elsewhere, but why does my receiver get a 5.1-channel 96/24-stream from bluray-images using the same connection (toslink spdif).

Not only that but Acer Revo 3610 is incapable of HD audio since it is a ION gen 1

case closed!

All dts-hd soundtracks contain a dts core soundtrack as well for hardware that cant do hd audio. Maybe thats what the receiver is getting.

All the ION will be doing is passing along LPCM up to 7.1
