Bug Description

Sometimes, almost always, Mixxx crashes when loading songs to first desck. Sometimes, even using auto DJ. The parent process is pasuspender. Further information in attached picture file.

My system is: Kubuntu 20.04. KDE Plasma 5.18.5 ; tested on another computer with same OS and different graphical environment (MATE) and same issue.

Please, fix it. I'm quite interested on setting up my own radio station and this program is superb!

Please upload you mixxx.log after a crash had happened. ~/.mixxx/mixxx.log

If you are able to reproduce that crash, a gdb backlog might be also helpfull:

Are all files affected, or only one special file or a group of files?

And the process using gdb doesn't really stop. I can't apply the command "thread apply all bt full"

Something relative to permissions? It seemed to work right under root account.

The output of gdb in terminal so far (normal user, not root ) is:

And the process using gdb doesn't really stop. I can't apply the command "thread apply all bt full"

Something relative to permissions? It seemed to work right under root account.

The output of gdb in terminal so far (normal user, not root ) is:

You have probably messed up your file permissions while running Mixxx as root. You didn't mention this before. This could be the cause of the crash.

From your initial post, I assume Mixxx immediately quits when crashing, right?
This should also stop the debugger for creating a back trace.

If this no longer happens, I suggested to use Mixxx as usually under GDB and wait for such a crash.

In case the issue is different, please describe what Mixxx does and what it should do instead when the issue occours.

Excuse me u both Daniel and Uwe. I read in Troubleshooting that Mixxx doesn't work under pulse in Linux. Even, it runs pasuspender to block it when running. I was trying to use "pulse" as output and input hardware to test the program.

Think that that was the problem. Congratulations to the programmers. Program is superb! Thanks. :-)

Thank you for you investigations.

For casual listening you can use the pulse device.
In order to that you need to start Mixxx without pasuspender.
This works, but has no good latency for scratching.

I must admit that this is not a good UX.

Is a bug already tracking the problem.
I think we can make this a duplicate.
If you have other issues, please file a new bug.
