running jack and pulseaudio

Hey,
I use pulse audio, but wanted to write a couple of small jack programs (got interested in it somehow), but I can't seem to get it running (I'm trying with the dbus interface). Doing jack_control start and then jack_control status reports false. My idea is to run jack on my soundcard (pulse is the default device in alsa) and let alsa dmix it, but is it even posible?
Any ideas on what I might do, or how I can get more info? I don't really understand how alsa works.

Re: running jack and pulseaudio

You'd need jack-audio-connection-kit-mp for it to work together with pulseaudio, not the dbus-ified jack1.

You really don't understand how alsa works, jack wants full control of the sound-card (and can get it, if you give it hw:0 and are using the version I recommend, else you'd have to kill pulseaudio or set it to not use the soundcard you're interested in). Jack doesn't go through dmix.

Re: running jack and pulseaudio

Hi, had some trouble and now I'm back to this.

I installed jack-audio-connection-kit-mp, but when I do jack_control start it doesn't seem to do anything.

~% jack_control start&&jack_control status
--- start
--- status
stopped

and from using jack_control dp I can see the device setting is set (or unset, actually) to hw:0.

edit: this is my asound.conf

pcm.!default {
    type pulse
}
ctl.!default {
    type pulse
}

Re: running jack and pulseaudio

Try killing pulse before starting jack, maybe for some reason its refusing to release the soundcard. Also check your logs in ~/.log/jack/jackdbus.log for hints.

Next time, new issue should mean new thread. Clutters things, otherwise. Also people are normally more willing to read threads with 0 replies.
