I fixed the hanging/non-return issue, I can tail the fifo file and it is
being written but not being picked up by mplayer.

It does not seem to matter what I send mplayers stdout/err to (null or
the pipe).

So a little progress anyway. Could the backgrounded while-loop that
mplayer runs in be involved? It does not seem likely, player should
still see the pipe/file.

This is the guts of the loop, I need to send output somewhere to get
control back when I bg it, so I think the 'done' line need to stay as
is.

  while ....
   do
     ...
     ${MPLAYER} -slave -input file=/data/cm_temp/mplayer_cmds_fifo \
       -quiet ${TRACK} &> /dev/null
      ...
   done < ${PLAY_LIST} &> /dev/null &
