Plugins with Effect Preview Causing Reproducible Crashes

Hi everyone,

This is my first time posting. I have used Audacity for years to record, repair, and alter audio, and this is the first time I have tried to use effects that caused the program to crash every time they are used. I don’t get an informative error message for any of these crashes, just an option to submit a debug report. I have no idea what’s going on, but I do know that I did not notice these issues until I upgraded to Fedora 29 and reinstalled Audacity. I have used Linux versions of Audacity since at least Fedora 27 without encountering these issues. I get the same problems on Fedora 29 with Audacity 2.2.x and 2.3.x regardless of whether I download the program from a repository or the Audacity home page.

What I have noticed about this problem is that the effects that are broken are the ones that offer previews of the effect prior to application. Most of the effects are working, but it would be nice if I could use Phaser and WahWah again. I’m not having any other trouble with Audacity. Recording and playback work fine.

Are there any fixes for this problem? Does anyone know what’s happening here?

A list of which effects work and stats about my computer follow.

Effects that do work:

Auto Duck
Change Pitch
Change Speed
Change Tempo
Fade In
Fade Out
Noise Reduction
Sliding Stretch
Truncate Silence
All plugins in the “Plugin 1 - 15” menu and “Plugin 16 - 17” menu

Effects that crash:

Bass and Treble


I’m using Audacity v.2.3.0 on Fedora 29 x86_64
NVIDIA Corporation GP106 [GeForce GTX 1060 6GB]
I am using ALSA audio and Audacity shows no option to switch to Pulse. Pulse is not even in the drop-down menu.
I’m using the audio output/input from my PC’s motherboard. I also have a small TV attached via HDMI that I use as a monitor, and audacity gives me the option to output through the TV’s speakers.
The error message I’m getting is not detailed. It is just an offer to submit a debug report. I am always able to recover Audacity and the file I’m editing.

This is a known problem in Audacity 2.3.0, and is one of the main reasons that Audacity 2.3.0 was released for Windows and Mac only. For Linux, the official release versions jumped from 2.2.2 to 2.3.1 (missing out 2.3.0). The bug was fixed on 2018-10-02.

As far as I recall, this was not a known bug in Audacity 2.2.2, and I certainly don’t see this issue with 2.2.1 on Ubuntu.

Thanks for the quick reply!

It looks like this is a problem with Fedora’s repositories more than it is a problem with Audacity. I was not aware of the 2.3.1 version because 2.3.0 seems to be the most recent version of the program Fedora 29’s repositories offer. I guess they do not know about the issue with the earlier version and included the .rpm for it anyway.
