Inputs/Outputs with jack [RESOLVED]

Hi everyone.
I’ve an M-Audio Fast Track Ultra, it works fine with jack.
I do not achieve to have the 8 I/O in SuperCollider. Only in_1 and in_2.
Even if I add the env “system:capture_1–>8” to my bash_profile,
“scsynth -u 57110 -a 1024 -i 8 -o 8 -R 0 -C 1 -l 1” runs the 8 I/O,
but when I boot the server under sclang , it returns to 1 and 2.
A little help with this ?

Ok done, I’ve just add a sclang startup file.
