First off, this problem is more of an annoying repeated error message than an issue. I’m no Linux expert by any stretch (let’s get that out of the way), I’m tinkering with my Raspberry Pi to have a self-contained recorder for jam sessions. I’m using Audacity 2.4.2 on my Raspberry Pi 4 4Gb running Raspbian GNU/Linux 11. Audacity was installed using PiPackages 0.1.0, if that is of any relevance.
At every launch of Audacity, I get the following error message: “An assertion failed! .'/src/AudioIO.cpp(973): assert “false” failed in AudioIO()”
The backtrace gives only the following:
ASSERT INFO: ./src/AudioIO.cpp(973): assert "false" failed in AudioIO(). BACKTRACE:  AudioIO::AudioIO()  AudioIO::Init()  AudacityApp::OnInit()  wxEntry(int&, wchar_t**)  main  __libc_start_main
It doesn’t affect functionality, I record input from a USB audio capture device using ALSA drivers.
The annoying part is that I uncheck “Show this dialog the next time”, but the message still reappears at launch. I’ve even run the program from command line as sudo, unchecked the box and clicked Continue, but the error still appeared the next time.
