I'm trying to record audio on my laptop's build-in microphone. It worked fine before I installed Xfce. But now the audio recording always contains a bunch of unwanted noise even when I don't make any sounds in the real world. I tried plugging in my headphones and unplugging them, and the outcome is the same. It seems to be some kind of computer-generated noise added to the sound recording.
How do I get rid of this audio recording noise?
