Linux: Pattern playback speeding up and going silent

[nemiush]

Hello,

I’m not sure if this is specifically a Renoise problem, but I’m not noticing this issue with any other program I use.

When hitting play on my project, after a few seconds of playing, it will suddenly go silent, and speed up, cycling through the pattern a bunch. This issue will last for minutes at a time, and trying to play a sound with my keyboard while paused still only elicits silence. Additionally, the screen will also cut to black for a few seconds. This happens for any project I open, new or old. It happens regardless of what plugins I use. I just tested it, and it doesn’t happen in a totally empty project, but as soon as I load in a sample, the glitch is triggered.

I am using Renoise 3.4.4 on Linux Mint 21.3 Cinnamon, and my audio device is ALSA.

Thank you for your help, and I apologise if this is not the right place to ask this question.

EDIT:
Steps to reproduce:

1. Open Renoise
2. Load in a sample or a VST instrument, doesn’t matter what
3. Begin editing in pattern editor, hit playback
4. Glitch occurs (either immediately after, or with a bit more editing)

For example, is it in performance mode?
It is possible that the buffer settings in pipewire’s quantum or other buffer settings are severe and need to be increased.
I run the following shell script with the window manager keybindings and use the performance mode and listening (powersave) mode depending on the situation.

$ sudo grep cpupower /etc/sudoers.d/wheel
%wheel ALL=(ALL:ALL) NOPASSWD: /usr/bin/cpupower
$
$ cat ~/.local/bin/cpupower-performance-toggle.sh
#!/bin/bash

if $(cpupower frequency-info | grep '"powersave"' > /dev/null) ; then
    sudo cpupower frequency-set -g performance
    pw-metadata -n settings 0 clock.force-quantum 192
else
    sudo cpupower frequency-set -g powersave
    pw-metadata -n settings 0 clock.force-quantum 2048
fi
$

However, it would be better to ask this kind of question here rather than here.

I think the community for the OS you are using is also an appropriate place to ask questions.

Ah, but with ALSA, the pipewire setting may not matter.

looks like you should check Renoise with its default settings.
Please exit Renoise, backup (rename) ~/.config/Renoise/V3.4.4/Config.xml and start it again to check.

Hi, thank you so much for your answer,

Replacing the config file seems to have helped. I can’t really tell what exactly caused the problem, but it’s all working now.

Yes, I am guessing that this is probably related to this area, but I am glad that the problem has been resolved anyway.
