 > I did some Googling around of "ALSA underrun scheduler" and found
 https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/190754 and
 https://bugs.launchpad.net/ubuntu/+source/linux/+bug/188226. By enabling
 group scheduling and forcing all applications to be in one group by
 disabling per-UID scheduling groups, I can run TamTamMini for 10+ minutes
 with an average of < 1 underrun per second.

 I meant "< 1 underrun per minute", which is a large difference.
