Here’s screenshot of the way Audacity and Gnome ALSA mixer is setup, and with which I can’t get any streaming in for recording.
I’ve tried lots output / input combinations - none work for streaming audio.
See anything that is messed up and needs changing?
I may have solved the problem. The “PulseAudio Volume Control” that I got during a download didn’t look like what is pictured in the tutorial you linked - there was no access to the tabs shown.
Just now I uninstalled what I had, re-installed, and got a “PulseAudio Volume Control” that looked like what’s in the tutorial.
I changed to “analog stereo output” in the config tab, and started getting recordable input in Audacity.
