Comment 13 for bug 85547

I too believed that the problem lied with my mic, but i then realized the problem actually lies with the sound recorded in Gnome. The problem is simple: you can't play back the audio stream unless it's saved first, actually you can click the play button but you'll get silence in return. I guess a lot of people have stumbled upon this issue and reported their mic doesn't work. What's even more annoying is that choosing "save" instead of "save as" leads to a "invalid parameters" error.
