The mas_initialized and mas_mode fields in STAT packets are obsolete and unused. Quite a lot of effort goes on in SC to keep track of the player status based upon what commands have been sent and what status indications received. This sometimes fails.

It would be useful if the STAT command reported actual status (stopped/buffering/playing/paused, decoder-running, audio-stream-connected, next-track-buffering, ...).

I am not sure exactly what status should be reflected nor how it should be used. This is a place-holder so that we can keep this in mind.
