Recording (audio) in Google+ Hangout?

view full story

http://askubuntu.com – There are a fair number of "recording video" questions, but the slight twist to this one is that all I want to record is the audio of weekly tutoring sessions I'm doing via Google Plus. The video wouldn't be all that useful (I'm learning Django, and my recall rate of what we actually did is pretty high, once I have the audio cue). I've tried Audacity twice -- once, it could only record my incoming audio (my tutor) and not my outgoing (me); the other time, it managed to not only record nothing, but deactivate my audio-in to the point it took a reboot to bring my mic back.
