Besides what is in the basic help section, how else can I fix my mic not working?
My mic simply stopped working for this website. I can still google hangout, skype, record songs using both internal and external mics, and in general use my internal mic for everything except this website. What gives?
Check to see if you unchecked the "Use microphone" box in the Profile section of your Settings. If that's not the problem, allow Duolingo to use your mic. (I'm not sure how to do that manually though.)
