While the code makes sense, I am wondering if this is the right solution. This would typically need to be handled by a policy framework instead of making hard-coded decisions? what if you get a ringtone, do you really want to keep playing your video? At the very least there should be a whitelist set of stream types that have higher precedence than pass-through and that don't get routed to the null sink (could be passed as options to the module) -Pierre
