I'll look into the log, but I can't ignore the feedback because this is what allows me to confirm me that (e.g.) playback has started and that would have many ramification in the state machine to inform LMS of the status. In addition, I really hate using timers, usually they are crutches that ultimately lead to disaster. In any case, for command like play/pause/stop, the cast protocol offers a transaction ID that I'm using to discard any status information ID that is older than the most recent request ID, so it should be filtered out (I mean a "'paused" status polled after a "play" request has been sent will have a transaction ID lower than the play request ID and will be ignored). I'll investigate to see if there is some race condition. Still, the volume has a filtering timer to avoid ping-pong of the echo effect (i.e. when I send a command, every feedback is ignored within 1 sec) but volume is not an event, it's a status (like everything), that's why the "request 0 and read -anytime- that 3 got set" in your case was still failing, no filtering loop would have avoided that, no transaction ID would either.
