is it possible ?
I'm streaming stuff from PC to PS3 - and its all AC3 - but no matter the settings I can't get the PS3 to not decode to 5 channel PCM
any ideas please ?
What software are you using to stream?
I stream HD movies with DD 5.1 audio with no issues using TVersity however i believe the PS3 will not playback DTS on streamed or locally stored media files (someone correct me if I'm wrong) If i get a video file with DTS i notice that MKV2VOB specifically re-encodes the audio stream from DTS to AC3.
Have you tried disabling all of the 5.1 and 7.1 PCM options in the PS3 audio settings? this worked for me
