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. ====================================================================== ---------------------------------------------------------------------- pzad - 02-21-05 15:04 ---------------------------------------------------------------------- Do you mean playing stereo sound using spdif has swapped left and right ? Channel swap in Audigy2.conf is needed for AC3 (DTS) passthrough.
