Mono isn't particularly defined for I2S at the best of times; the
clocking is inherently stereo.  You may just pick out the left channel
or you may duplicate things on left and right channels (at which point a
polarity change won't be noticed).  I wouldn't worry too much about it,
it's better to have things the right way round and fix up configuration
for machines that need it.
