Can you make the file available so I can look into it?bewa wrote:Has anyone seen if this is fixed?
The problem i get (which i think is the same or similar) is when playing 6 channel AC3 (Dolby Digital 5.1) and downmixing to Stereo.
The audio is all over the place.
I've played with pretty much every combination of Audio settings in OpenElec and I tried raspbmc and it was the same.
He's the audio info for one of the files:
