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.

Thanks. I'll give audacity a try next time I need this. I already used the Pavucontrol tool with gnome-sound-recorder but never got any audio. Also tried ffmpeg which never recorded any audio using any of the instructions I found.
video downloadhelper has been working well for me, YMMV,...

I've explained the details below about how to capture local audio, but as Jack mentioned, it might be easier to download the source video and extract the audio directly from that.

In audacity, click the record monitor so it opens a connection. Then in pavucontrol, go to the recording tab. Beside the entry for audacity will be a dropdown. The actual text depends on your audio device, but you want to select the "monitor of" entry. If you have something playing, you should see the volume monitor bar moving.

obs should work, though I've never captured without both video and audio. Once you have the captured file, you can extract the audio with mplayer, ffmpeg, or import it to audacity and then export the audio as a new file.
I have fullscreened firefox and used OBS to capture both the video and the audio, it seems to have worked correctly.

There's the brute force and ignorance method: Connect a 3.5 mm patch lead between line out to line in, and record the line in signal.
Obviously there can be some quality losses doing it this way, but they may be insignificant to you. And it gets around all technical attempts to stop you copying the sound.
