We're using Skype, although I also encountered this last week when using
Mumble. Mumble users were complaining that my game sounds were coming
through instead of my voice whenever I hit the push-to-talk button. :)

I confirmed today by using pavucontrol that my friend had the Skype
input coming from the Monitor source, and switching it manually to the
microphone worked.

I can only pray that this 'race condition' doesn't occur again, and that
the selection stays that way.

God forbid he ever use Ubuntu's 'Guest session' feature to let a friend
sign in to Skype which will start up a fresh PulseAudio with no
remembered stream settings, and will probably have the guest session's
audio input go awry.

This seems to happen fairly regularly, so if I notice again, I'll
definitely do that.

Cheers,
Jeremy.
