I can change it in the next round of updates. Right now I'd like to
get some people testing it and maybe doing some patches to enhance it.

For example I know he code has a problem where about 5% of the time
the codec doesn't reset right on boot. Someone needs to put an
oscilloscope on the codec chip and tell me why it is failing.
