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. ====================================================================== ---------------------------------------------------------------------- jcdutton - 03-19-05 11:46 ---------------------------------------------------------------------- A proper fix for this is using DSP code. I recently posted an email to alsa-user with a patch for people to try, who are having problems with AC3 out on the raw iec58 device. So, depending on their feedback, it will be fixed soon. ---------------------------------------------------------------------- perex - 05-30-05 13:41 ---------------------------------------------------------------------- Reporter - is this bug fixed in 1.0.9?
