Hello,
How can I make Jackd always run? Right now I have to set it up in a
console window. I'd like to learn how to run it always at startup and
not have to start/stop it when I need it.
I use an init script like this:
andy@xfc:/etc/init.d$ ls -l jackd
-rwxr-xr-x 1 root root 852 Mar 11 21:50 jackd
For a SysV-style init, (most linux distros), add a symlink to start it up
automatically for the default runlevel (2 is the default runlevel for a
debian system)...
root@xfc:/etc/rc2.d# runlevel
N 2
root@xfc:/etc/rc2.d# ls -l S20jackd
lrwxrwxrwx 1 root root 15 Apr 21 14:39 S20jackd ->
../init.d/jackd
To see what is going on, run this in a console:
# /etc/init.d/jackd monitor
I include LADCCAD in the init script also.
----------------------------------------------------------------
case $1 in
'start')
echo "Starting Jack Audio Server with period of 256 samples."
# LADCCAD ...
rm -f /var/log/ladccad.log
ladccad 1> /var/log/ladccad.log 2>&1 &
# Jack Audio Server
rm -f /var/log/jackd.log
jackd --realtime -v -d alsa -d hw:0 -r 44100 -p 256 \
1> /var/log/jackd.log 2>&1
;;
'stop')
echo "Stopping Jack Audio Server."
killall jackd
killall ladccad
;;
'restart')
$0 stop
$0 start
;;
'start-monitor')
$0 start
$0 monitor
;;
'monitor')
tail -f /var/log/jackd.log
;;
*)
echo "Usage $0 [start, stop, restart, monitor]"
;;
esac
----------------------------------------------------------------
The above script should be tweaked as necessary for your setup.
