Hello fedyarov,

thank you for your reply.

Exported .wav files are ok.

I've tried to launch ./lmms-1.3.0-alpha.1.102+g89fc6c9-linux-x86_64.AppImage from a terminal.

Startup messages:

Carla does not appear to be installed. That's OK, please ignore any related library errors.
Jack appears to be installed on this system, so we'll use it.

I'm currently NOT using JACK (with ALSA audio driver); what will happen when I install jack?... To be continued...

Question: do you have KXStudio repos enabled? Which version of JACK are you running? Ubuntu repos are often not up to date, whilst KXStudio's ones are (and contain many utilities - like cadence, catia, ...).
If the render is fine, that's the only thing that matters. :)

I also get those messages 'not an Ogg Vorbis file' when I try to render the recommended Greippi demo with LMMS 1.3.0-alpha. They are absent in 1.2.2. This may be a bug.

No, I'm not using any additional repos, except for http://ppa.launchpad.net/kivy-team/kivy/ubuntu (cross-platform programming framework I once tried) and http://repository.spotify.com, I don't think they make any difference here.

The 'jackd -V' command reads 'jackdmp version 1.9.12 tmpdir /dev/shm protocol 8'. The package manager mentions '1.9.12~dfsg-2'.

The problem may turn out to be that your system is actually too new, not too old... Here's what I get rendering one of my tracks with 1.3.0-alpha (sorry for the Ukrainian locale):
