sleep 36000, double coffee and fixed in git.

There are plugins with 9 audio input and/or 9 audio output,
for example "Ambisonics Rotation" and "Step Demuxer".

There are also plugins with 0 audio in and 1 audio out and viceversa,
therefore the new syntax is

  [aout1, aout2, ..., aout9] dssiaudio ihandle, [ain1 ,ain2, ..., ain9]

and no segfault
