trouble getting jack to work...
« on: July 29, 2010, 11:14:23 »

Hi,

i am running a ubuntu jaunty kernel with ubuntu packages and I can't get MT to use the Jack audio driver.
First I tried MT v0.90.80 and it said: "JACK: Can't load libjack (is it installed?)"
... although these files were present in /usr/lib/ :

# ls libj*
libjack               libjackserver.so.0       libjack.so.0
libjack-0.100.0.so.0  libjackserver.so.0.0.28  libjack.so.0.0.28

libjack0.100.0:
inprocess.so  jack_alsa.so   jack_firewire.so  jack_net.so
intime.so     jack_dummy.so  jack_freebob.so   jack_oss.so

~~~~~~

Next I compiled v0.90.85 from source (with and without patches, makes no difference). The select driver dialog now offers: alsa | sdl_audio.

I get the following errors when switching between alsa and sdl_audio with different buffer sizes:

# /usr/local/bin/milkytracker
ALSA lib pcm_dmix.c:874:(snd_pcm_dmix_open) unable to open slave
E: socket-client.c: socket(): Address family not supported by protocol
SDL: Failed to open audio device! (buffer = 8192 bytes)..
SDL: Try setting "Force 2^n sizes" in the config menu and restarting.

edit: deleted the similar err. messages.

I wonder if jack support is present here?!

When building from source, Jack support will only be compiled if the Jack development libraries are installed on your system.  If you look at the output of the ./configure script you will see a message which reports whether this has been detected or not.

As for the error messages you pasted, it seems that SDL cannot successfully access the ALSA driver - you could try forcing SDL to use a different driver (see the readme_unix file for details of this).  I think Ubuntu uses Pulseaudio by default.

Thanks for the quick hint!

I got libjack-dev and everything is fine.

As for the sdl_audio/alsa errors: these drivers work also - jack was running using them (single client). I dont use pulseaudio here on puppylinux.

Thx a ton!
