Should deal with audio input being muted in pulseaudio
Submitted by Guillaume Desmottes
I did a test call and was wondering why my voice wasn't recorded. I discovered that my USB microphone was muted in pulseaudio; unmuting it fixes the issue.
I never mute it manually so that way be a pulseaudio issue but, anyway, Empathy should deal with this case as that can be very confusing for the user.
I see at least two potential ways to fix this: a) Automatically unmute input when we need to use it b) Warn user using a GtkInfoBar or something and add a button to unmute the mic.
