Yes: all the time (from TV Apps). You sure have spun a lot of cycles (and posts) with this problem. Let's try one more time:
1) connect an optical cable (forget ARC)
2) select "optical audio out" from the sound menu
3) go into Netflix (or Amazon) and play something with a known 5.1 track
If you're AVR doesn't show "Dolby Digital" or light up 5 channels, then you have defective hardware.
