Netflix & no sound.

When I switch over to Netflix in apps i suddenly have no sound.  It was working a few days ago.  All my other apps work fine just Netflix.  Why?

I've solved it in settings/Audio visual.  For some reason Digital audio output HDMI had a tick against Dolby Digital Plus where it should be just Dolby Digital.
