I was trying to record a great new Dr. Jaynes music video on Audacity and I realized that the mic level was so low that I could hardly hear it. I tried adjusting the microphone level in audacity, but he slider would not budge. I just install new versions of both Audacity, and Ubuntu and nothing is works as it used to. It took me a little while to figure out how to change the mic level, to boost it to a reasonable audio level. I actually ended up having to go in to settings to fix this issues. This video show how to adjust recording audio level of the microphone on your computer.
