lmms-1.2.0-rc8-linux-x86_64.AppImage : no sound with JACK

Created on 23 Feb 2019 · 14Comments · Source: LMMS/lmms

I have a bug, confirmed by another user on french forum, with lmms-1.2.0-rc8-linux-x86_64.AppImage on LibraZiK distro (based on Debian Stretch). If I choose Jack as Audio interface, I have no sound, I can see sound is working in the master track in the mixer, but no output. It works nicely with previous versions (AppImage rc6, rc7).

Jack does not appear to be installed.  That's OK, we'll use a dummy version instead.

Here's a build with /sbin added to $PATH per e54969c. https://github.com/tresf/lmms/releases/download/v1.2.0-RC8/lmms-1.2.0-rc8.8-linux-x86_64.AppImage

Are you sure that you've installed JACK? Without locally installed JACK server, the AppImage can't play audio via JACK.

Yes, Jack is installed , and as I said, it's works with 1.2.0-rc6 and rc7 (with Jack)

Then could you post the terminal output of RC7 with JACK?

It seems like your system doesn't have ldconfig, right?

PhysSong on 23 Feb 2019

It is normal that ldconfig is not available to regular users. ldconfig is not required for a working system either. cmake/linux/package_linux.sh.in should be fixed.

I dont know if there is another similar issue, but no sound with Vestige using pulseaudio output on rc8. I've tested on archlinux rc8 package (available in oficial community repo) and lmms-1.2.0-rc8-linux-x86_64.AppImage with same results. No problems with rc7.

ldconfig is installed on my system (in /sbin/).

sub26nico on 2 Mar 2019

The same thing happens to me but in my AV Linux 2018 distro. I can not use rc8 for this same audio error, and I do not know what to do, I do not see any connection of LMMS with Jack; however, I do not have that problem in rc7. rc8 has many improvements but it takes a long time for stable 1.2 to be released. right now debian users can not use rc8.

Is it possible to make a pr or a patch with this bug fixed?

I'll take a look.

Same here on Debian 9.7. If previous versions worked there may have been a bug see also fc9c3ea / #4186. Anyway, the ldconfig approach is our workaround and it's how we have to handle this for libraries that we can't safely bundle along side LMMS. I'll upload a build for testing shortly.

/sbin isn't in the search path and the AppImage can't use ldconfig unless it is, so I've added it to the search path, which fixes the ./AppRun: line 18: ldconfig: command not found problem. Should be fixed with e54969c. If not, we'll have to play git blame some of the recent commits to stable-1.2. :D

@tresf , i have quickly tested (just made a little beat in the drums and bass editor) this v1.2.0-rc8.8-linux-x86_64.AppImage, and it works with JACK, thanks a lot.

Working now again! Thanks so much for the quick response.
