Blender shouldn't try to start jack if already started
Closed, InvalidPublic


I use blender under debian. For my sound, I use gladish, thus jackdbus and not jackd.

When I start blender, or when I select jack in the properties it tries to launch jackd, which is impossible with jackdbus activated, so it fails and I got no sound at all.

Please note that the debian's blender package behave as expected : it creates the proper jack outputs, without trying to launch jackd.

Thanks in advance.

All the best.

Joerg, can you please look into this? Thanks!

Jörg, any updates here? Thanks. :)

is the server is already? or is it that jackdbus is running but not the server?
what happens when you type "jackd" if jackdbus is running?

I talked back again to the jack people and here's what I found out:

[12:59:14] <nedko> having both jackd and jackdbus installed is receipe for trouble
[12:59:36] <nedko> in case they are both installed, jack server autostart must be properly configured
[12:59:52] <nedko> whether the user wants jackd or jackdbus is user preference
[13:00:47] <nedko> when jack is compiled with both jackd and jackdbus, libjack will use the the classic autolaunch mechanism, by executing the commandline specified in ~/.jackdrc
[13:01:08] <nedko> that can be made to start jack server through jackdbus, or even through ladish
[13:02:55] <nedko> the autostart feature configuration is described in the jackd man page

So there's not much we can do on the blender code side. Closing this for now.
