Example: This produces "correct" left and right mappings extract_ac3 AC3TEST.VOB |ac3dec The following, however, reverses left & right: extract_ac3 AC3TEST.VOB |ac3dec -R Likewise, when playing a dvd with mplayer, things are correct if i merely use -ao alsa, but end up with left/right reversed if i use -ao alsa:device=iec958. It appears to be an error in Audigy2.conf - changing the line value [ 255 255 0 0 0 0 0 0 0 255 0 0 0 0 0 0 255 0 0 0 0 0 0 0 ] to value [ 255 255 0 0 0 0 0 0 255 0 0 0 0 0 0 0 0 255 0 0 0 0 0 0 ] as in Audigy.conf, makes the channels appear from the right speaker even when using the raw spdif device. ====================================================================== ---------------------------------------------------------------------- TheOrwithVagrant - 02-21-05 15:14 ---------------------------------------------------------------------- Yes, stereo sound gets reversed. AC3 passthrough, whether DTS or DD, has sadly never worked for me with any version of alsa, regardless of whether i leave Audigy2.conf untouched, or tweak it to fix the channel reversal as above. It was in my long toilings with trying to get _that_ to work that I noticed this channel reversal bug/feature. ---------------------------------------------------------------------- rlrevell - 02-22-05 03:59 ---------------------------------------------------------------------- FWIW, there is an open bug report for the same issue with the Audigy 2 EX.
