Summary: Left/Right reversed when using the raw iec958 on
Audigy2
Description:
When using an spdif-attatched amplifier, the iec958/spdif raw device to
play a sound (or video file), the left and right channels end up
reversed.
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.

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.
