Setting the default audio output to jack

Question

I have a Raspberry Pi with PiPlay and I'm trying to set the default audio output to analogic, but It doesn't work. I tried to change the audio settings in raspi-config but It only works on the current session. Thanks!

SOLVED I edited the /home/pi/piamame/config/piplay-sound.state because I found It was a problem when changing from text mode to graphic mode and I changed from this:

control.3 {
    iface MIXER
    name 'PCM Playback Route'
    value 2
    comment {
        access 'read write'
        type INTEGER
        count 1
        range '0 - 2'
    }
}

to this:

control.3 {
    iface MIXER
    name 'PCM Playback Route'
    value 1
    comment {
        access 'read write'
        type INTEGER
        count 1
        range '0 - 2'
    }
}

According to How to make Raspberry use HDMI audio as default system output?, all you need to do is:

sudo amixer cset numid=3 1

To test your audio, you can run:

cd /opt/vc/src/hello_pi/hello_audio
make
./hello_audio.bin

NOTE: You will only need to run the make command on the first time.
