Yamaha amplifier connects via HDMI to TV . The TV sporadically stops the audio for DSTV device when switching between this DSTV device and separate android multi media box . Sound settings : Output: TV Speaker | Digital Output Audio Format: PCM or Auto ( no pass through option) | auto volume: on or off (makes no difference) | simultaneous optical output : off or on ( no difference) . Software version : 1310. Also tried 2 separate HDMI cables . Help !? Warwick
