This is a start.  I had seen that but noticed that the script segment 
talked about Direct TV so I thought this may be tied to capturing 
external audio, not the audio from cable.  I noticed that the problem 
went away for a few days after a reboot too.  I just don't want to be 
rebooting since this always messes up the firewire on my DCT which then 
requires some fussing to get working again.  I'll try to reset the audio 
like in the Wiki on both tuners once I notice the audio chirping again 
to see if this helps any.
