I'm playing a video in firefox and want to capture the audio.
There are a maze of web pages about audio capture, all different.
None of the ones I've tried work. They all give the impression they
are capturing audio, but the resulting audio files are nothing
but silence.
Has anyone successfully captured audio from firefox on fedora 33?
Assuming you run PulseAudio, the tools that you want are Pavucontrol
and Audacity. Pavucontrol controls the paths through which sound moves
in the PulseAudio system. Audacity records it. Both are pretty
intuitive. When you start Firefox it will show up as a source in
Pavucontrol, similarly Audacity will show up as a sink.
