Hi I've read from assorted sources that accurate channel mapping of a AC3 stream through a A52encode to then produce output just doesn't work correctly? Is this still the case or is there a method to be able to work out which channel in the original stream should map to which channel on the output then be able to configure pulseaudio to output correctly? At the moment the front left/right appear to be coming out the rear and the centre seems to be coming from the left/right front speakers........rear and woofer sounds don't appear at all!! Any pointers or advice gratefully received. J
