Description

I use version 0.8.113 of zrythm under Fedora 30 64 bits
I use a realtime kernel with jack correctly configured.
When I start zrythm, I've got a lot of xruns.

The real time kernel comes from this repo:
https://copr.fedorainfracloud.org/coprs/ycollet/linuxmao/

Jack version: 1.9.12

#4 Updated by Alexandros Theodotou 3 months ago

strange, everything looks fine so i am not sure what is causing the xruns. needs more investigation. thanks for reporting it!

#5 Updated by Yann Collette 3 months ago

I use TuxGuitar and Guitarix with this jack settings without problems.
I will try to recompile a 0.7 version of zrythm to see if the problem was already there.

#6 Updated by Yann Collette 3 months ago

The problem was already there on v0.7.573 and v0.7.093/
v0.6.502 is segfaulting on Fedora 30.

#7 Updated by Alexandros Theodotou 3 months ago

does your DSP meter in the top right become full?

#8 Updated by Alexandros Theodotou 3 months ago

  • Target version set to 1.0.0

#9 Updated by Alexandros Theodotou about 2 months ago

  • Status changed from New to Rejected

i don't think this is a bug with zrythm - nothing to suggest that from the logs either. it sounds like a problem with the jack configuration

#10 Updated by Yann Collette about 2 months ago

I configured my Fedora 31 using https://github.com/raboof/realtimeconfigquickscan
I am able to record in real time audio + video without any xruns with a configuration which includes:

  • tuxguitar
  • guitarix
  • non-mixer
  • ray session
  • simplescreenrecorder
  • xawtv

But when I just start zrythm with qjackctl I've got around 10 xruns by seconds just by starting zrythm.
So, there is a problem with zrythm ...
