I can confirm the left signal comes out on the Ring of the jack, which should be right.
However if you input a signal into the Wizard (or Alchemist) and use e.g. the Gain patch: https://dev.rebeltech.org/patch-library/patch/Gain, then what goes in as left, comes out as left, and vice versa.
But now I've found the culprit: it's the footprint!
The pin highlighted green above should be the
OUT_LEFT signal, but in the connector it actually connects to Ring, ie right, of an inserted jack. Which is surprising, seeing how it is positioned nearer to the back than the Tip / left signal.
Since we use the same footprint for the input jack, this means we're swapping channels twice!
Fortunately the codec that we use, CS4271, has a Left/Right channel swap function. I'll try to come up with a solution and include it in the next firmware update.
