+*** System audio limitations
+:PROPERTIES:
+:CUSTOM_ID: bbb-audio-limitations
+:END:
+
+Sharing system audio by changing the audio device to "Built-in Audio Analog Stereo" is very choppy, only gets captured in the recording if I'm using Firefox (not Chrome) AND there's at least one listener, and doesn't allow simultaneous narration from the speaker.
+
+Using pulseaudio to change the app's recording device to the audio monitor results in smoother audio (because it's pretending to be the microphone), but still doesn't allow simultaneous narration from the speaker.
+
+Combining microphone + system audio into a new virtual microphone source is probably more complicated than we want to walk speakers through.
+
+BBB says sharing system audio works only if you use Chrome on Mac OS X or Microsoft Windows (https://support.bigbluebutton.org/hc/en-us/articles/1500005315642-Can-I-play-a-video-using-screen-sharing). I tested it on Linux and sharing system audio is not an option. If you happen to know of any more elegant way to do this, I'd love to hear it.
