Audio Recorder not recognizing built in Mic signal but PulseAudio Volume Control does. Linuxmint 21.2 Cinnamon installed on 3 computers. Recorder is installed on 3 computers, MacBook Pro laptop, iMac and Dell inspiron 1520 laptop. Configured the same on all 3. Does not work on Dell laptop. It did work on Dell laptop until I upgraded to 21.2. I reinstalled Recorder but still does not recognize signal from internal mic even though pulse does.
I am referring to the Pulse Audio Mixer (pavucontrol)
I did install and try "Recorder" simple audio recorder from https://github.com/alexkdeveloper/recorder which did not record anything either. Will Install Audacity to see what happens. Since pavucontrol gets input from the internal mic, that makes me think it is not a hardware problem. audio-recorder was working before I upgraded 21.2.
I am going to install 21.1 on another drive and see what happens.
Thanks for the information. The more precise the input, the more accurate the output.
I have no experience with that application and I regret to say that I don't have any clue as to what the problem may be, but I think your testing strategy is a good one.
I put a drive in the Dell laptop that has Linuxmint Cinnamon 21.1 on it. I installed audio-recorder from launchpad. It is recording sound from the internal mic.
