Crashing seconds after starting on Windows 10 Pro

[BounceBruhni]

Bug Description

I installed Mixx for the first time.
When I started it the Mixx-Launch-Window appeared, but then after one second it crashes.
While Looking over the LOCALAPPDATA-File of Mixx, I found an XML-File named Connection 1.bcp.xml .
After reading it, I thought it could have crashed because I started it offline. But it didn't worked in Online-Mode too.

Version

2.3.3

OS

Windows 10

This seems to be an issue with portaudio.

The installed mixxx crashed on me as well (Win 10 Pro) with nothing in the log file. So I checked the event viewer, which showed an error in ucrtbase.dll - a buffer underrun, which messes up the stack so it is not the actual error. Then I fetched the code, compiled mixxx as portable using VS2019 and it crashed there as well, following the stack trace it pointed to soundmanager.cpp line 256 on a call to Pa_Initialize():

Now, I am not familiar enough with the code - I just downloaded it and build it, plus cpp ain't my main coding language. Thought about rebuilding portaudio, but then I have trouble figuring out the different versions used, etc. So I just looked for another one on my box, found one, copied it to the mixxx directory and it worked.

Obviously that is not a proper solution, even if it works for me right now. Maybe someone more knowledgeable could figure how to actually build the portaudio.dll properly. The portaudio.dll I used was from my FlexAudio installation. So for anyone having trouble, they could try downloading that and use this as a workaround.

That is all the info I can provide for now.

Indeed. I uninstalled FlexASIO after your comment. Replaced portaudio.dll with the one that come with mixxx and the application does start fine.
