This was my interpretation of this comment of yours:

"Also should this be made a generic stop rather than
xrun. 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?

Thanks,
Charles
