I'm streaming to Twitch.TV everything working great, except I either have desktop audio, or microphone audio not both.

How can I get both?

I'm using avconv/ffmpeg with -f alsa -ac 2 -i pulse

also tried with hw:0

I've tried pavucontrol with the ffmpeg on pulse I can then choose game audio from the desktop or the microphone but not both.

What am I missing?
