Am probably misunderstanding the question: why not have the 
callback-function return either/both the data-received (or len() 
thereof) and 'status'?

NB don't know if incoming 'silence' is actually zero/null or if there 
will be values for 'static'/white-noise!

If revealed to be necessary, please explain further...
