I get a pop when entering a recording with AC-3 audio. It's because of  
this:

However, mine fixes itself just fine after the pop. If yours is still  
messed up and only sometimes, it sounds like whatever is decoding your  
audio (some sort of receiver I'm guessing?) isn't switching to digital  
every time. Is there a way you can force is to only use digital? I can  
do that on mine, but then I don't get my analog audio so I live with  
it the way it is until I am annoyed enough to fix it for good - which  
is likely never.
