The left and right stereo channels were reversed for most cases of
audiobusio.I2SOutonraspberrypi. See the table in #10230 (comment) for details.This was not a problem for
audiopwmio.PWMAudioOut, and not a problem for Espressif on SAMDI2SOut. The problem was that the data was in the opposite channel order expected. Interestingly, the sample programinFixed by flipping the LRCLK in three out of the four PIO programs. Also I put the PIO programs into separate files which are checked in, for convenience. They are not yet built automatically -- we could do that later.
Tested on a Metro RP2040 with an Adafruit Speaker Bonnet.
