[LAU] Linux automatic startup question

[john gibby]

Here, by the way, is the crossover_3chan contents:

  nano 2.6.2                                                File:
crossover_3chan

#!/bin/sh
export LADSPA_PATH=/usr/local/lib/ladspa:/usr/lib/ladspa;
#          -a:woofer2 -pf:./woofer.ecp    -chorder:0,0,0,0,0,0,1,2 \
ecasound  -a:pre1                -z:mixmode,sum -z:nodb -B:rtlowlatency
-b:64 -f:f32_le,2,48000 -i:jack -pf:./pre1.ecp -o:loop,1 \
          -a:pre2,woofer -z:mixmode,sum -z:nodb -B:rtlowlatency -b:64
-f:f32_le,2,48000 -i:loop,1 \
          -a:pre2 -pf:./pre2.ecp -o loop,2 \
          -a:mid,tweeter         -z:mixmode,sum -z:nodb -B:rtlowlatency
-b:64 -f:f32_le,2,48000 -i:loop,2 \
          -a:woofer  -pf:./woofer.ecp    -chorder:1,2,0,0,0,0 \
          -a:mid     -pf:./mid.ecp       -chorder:0,0,1,2,0,0 \
          -a:tweeter -pf:./tweeter.ecp   -chorder:0,0,0,0,1,2 \
          -a:woofer,mid,tweeter -z:mixmode,sum -z:nodb -B:rtlowlatency
-b:64 -f:f32_le,6,48000 -o:jack


I've discovered that if I invoke this script using the /usr/local/bin path
by just typing crossover_3chan, it also does not work - apparently b/c it
is being run or owned by "root" instead of gibbyj.  I.e., if I run it from
/home/gibbyj/Downloads it works, but if I type "crossover_3chan" from some
other directory, and it finds the script in /usr/local/bin, it shows up in
ps -aux with "root", and it doesn't work.  But when I boot the computer,
it's not even sbowing up in ps -aux, with root OR gibbyj...
Thanks again...
John
