Pulseaudio vs jack - annoying soundwar

Asked by EricDHH on 2009-05-21

Using 9.04 on 3 machines here, most apps are using pulse this days and audio mixing runs very smooth and well. But some apps depends on jack, this give us back the old soundwar with heavily blocked sound devices. If a jack app like lives calls jack, the pulse is blocked. No pulse app will play, firefox hangs without gui, banshee stood freezed. Some gnome desktop parts are blocked until jack was stopped, logout hangs several seconds cause it's blocked by jack.

I tried to switch jackd to pulse but there is no sink in the config, if jack is running all alsa and pulse are hard blocked. I feel back in stoneedge, like dos gaming with a specialized floppy for every game.

Is there a solution available?

When I record I use jack as audio server

In special situations like recording in windowze manner (everything stood still while one action is running) this maybe a workaround. But in normal usage we will run into several problems when software is using jack and pulse.

Both soundservers should work chained, without hard blockin, i feel this could be a bug.

If you believe could be a bug you report it
icp

The problem is that pulseaudio is in main and jack in universe, so Ubuntu can't build the pulseaudio-module-jack module. See bug #198048 and bug #109659.

I guess if you look around you might find a ppa that enables you to run pulseaudio on top of jack. Or you could build one yourself.

I will wait für 9.10, if this did not help i try an own build.

Thanks
