Perhaps the reason can be specified as an argument." If you clarify what you are looking for I am happy to respin. We should set the state to something that indicates there has been an error, such that things are distinct from a normal stop operation. Personally I liked simply calling the function snd_compr_stop_xrun and always setting it to xrun and it matches what the PCM framework does. So I am happy to go back to that if you prefer?
