Even after the recent app fiasco, my TV Autoplay settings were still functioning correctly. After a forced update via the Windows desktop controller this morning it is no longer working.
It seems that whether the switch in settings is set to ON or OFF, my living room speakers are now cutting off music and switching to SPDIF when there is a signal from the TV. (i.e Autoplay is always on no matter what I do to the settings.)
I already can’t listen to the music that I own at all, and now I can’t even listen to music via a service in my main room while the TV is on.
