I went back over my setup and I think it's still somehow tied to whole 
channel change process.

I noticed that in my channel change script, it sleeps 2 seconds before 
it returns to myth.  My notes indicate I had that up as high as 2.6 
seconds.  I've increased the delay 2.3 to see if that makes a difference 
and may try it higher too.

Before I made that change I caught another of these errors happen this 
evening.  I was able to flip over to the console and verify with 
v4l2-ctl that the input was set to SPDIF.   I don't have boost audio set.

I think I may have tried those patches in the past.  I don't have them 
applied at the moment.  I'll take a look at them again.
