Support for S16_LE could maybe be added if the tda998x specific codec
would fiddle with CTS_N predivider-setting (K select) according to the
used sample width. But it appears Cobox plays all the sample formats
fine without this change, so the question is if playing around with
CTS_N predivider would break already working support there (something to
