 Summary of the bug: While recording my screen and the output of 5 channels
 of sound I get very very choppy audio.

 My current work around is to create a loopback device in pulseaudio and
 output to my headset then record from that, but there is a tiny delay
 making it not sync up.

 How to reproduce:
