Revision as of 17:47, 2 September 2012

Install jackd1 (not jackd2 since it depends on dbus, meh). Make sure to enable rtprio and memlock permissions, the jackd installer on debian asks for this.

Put this in /etc/environment 

export JACK_PROMISCUOUS_SERVER=""

Make a new file /root/jackd_start, chmod to 755 and put this in it: 

#!/bin/bash

#make sure jackd is terminated when this script ends
cleanup()
{
  killall jackd
  exit 0
}
trap cleanup SIGINT
trap cleanup SIGTERM

#JACK_PROMISCUOUS_SERVER is exported here and in /etc/environment
#this tells jackd and libjack to use /dev/shm/jack instead of /dev/shm/jack-<uid>
#and to set the permissions to 777, however umask needs to be set to 0 first
export JACK_PROMISCUOUS_SERVER=""

#allow rtprio and mem locking
ulimit -l unlimited
ulimit -r 95

#start jackd with -l passed to su to make the environment a login shell, restart when it dies
while [ 1 ]
do
  su -l -c "mkdir ~/.jackd; umask 0; jackd -R -d alsa -d jack51 -r 48000 -p 1024 -n 2 -i 2 -o 6 2>&1 | tee ~/.jackd/jackd.log" || true
  sleep 1
done

Put this in /etc/rc.local 

/root/jackd_start&

At the top of /etc/init.d/mpd change 

#!/bin/sh

to 

#!/bin/bash

Then change 

# Exit if the package is not installed
[ -x "$DAEMON" ] || exit 0

into 

# Exit if the package is not installed
[ -x "$DAEMON" ] || exit 0

#JACK_PROMISCUOUS_SERVER is exported here and in /etc/environment
#this tells jackd and libjack to use /dev/shm/jack instead of /dev/shm/jack-<uid>
#and to set the permissions to 777
export JACK_PROMISCUOUS_SERVER=""

#allow rtprio and mem locking
ulimit -l unlimited
ulimit -r 95

Use this /etc/asound.conf file 

ctl.jack51 {
    type hw
    #card 0
    card Audigy
}

pcm.jack51 {
    # "asym" allows for different
    # handling of in/out devices
    type asym
    playback.pcm {
         # route for mmap workaround
         type plug
         slave.pcm "surround51:CARD=Audigy"
         #slave.pcm "surround51"
         slave.channels 6
         route_policy duplicate
    }
    capture.pcm {
        # 2 channels only
        type hw
        #card 0
        card Audigy
    }
}
