You system should work with this

And I have not asked if you use any AV Receiver (5.1 DD or/and DTS decoder) connected to your TV over Toslink or SPDIF (Digital Optical or Coaxial output).

If Yes than your XBMC Audio output settings
Also make sure you have your TV Audio settings right, means you have to have Digital Output ON/Passthrough !!! If no than you would have your sound just from TV speakers.

Quote:Audio Ouput : HDMI
Speaker configuration : 5.1
Boost volume on downmix : Yes
Output stereo to all speakers : Yes
Dolby Digital (AC3) capable reciever : Yes
DTS capabale reciver : Yes

If No than your XBMC Audio output settings
Also make sure you have your TV Audio settings right, means you have to have Digital Output OFF !!! If no than you would have no sound at all from TV speakers.

Quote:Audio Ouput : HDMI
Speaker configuration : 2.0(try also 5.1 as the RPi out untouched sound stream and your TV should use built in processor to downmix the sound)
Boost volume on downmix : Yes
Output stereo to all speakers : (not sure, try both if you hear any difference
Dolby Digital (AC3) capable reciever : Yes
DTS capabale reciver : Yes

Thank you very much for the details. I will try all these.

I don't have any receiver connected. RPi connects directly to TV. I didn't not find any option to change HDMI audio in TV. On RPI when I run 'tvservice', it shows me that my TV supports DTS and AC3 passthorugh

yes your telly supports both DD and DTS (where when used with internal speaker or even with extended wireless speaker connected to your TV) the DTS will be downmix to 2.0!Thats the limit of built in sound processor which can decode DD to 5.1 but 2.0 in DTS format!
So you may leave the XBMC Audio output sett to HDMI 5.1 with external decoders ON and your telly should take care and downmix all to 2.0. So its much better in your case as the RPi CPU do not need to be used to downmix the sound so it should work much smoother

Hope it all make sense how I trying to explain
