All I know is that using sox, -B is needed on output when sending to a
Touch feeding my M1 CLiC player.  I don't know how the data is formatted
from Touch to Player, and whether this -B is for compatibility with the
Touch or with the player.  I believe that the reason I had to upsample
my 16/44100 tracks (to 24/88200 rather than 24/44100) when using sox to
send 24 bit samples, is that maybe the Touch can't handle 24/44100 data
(my player claims to be able to do so when receiving UPnP music over
ethernet - LPCM format).
