Rating: 5/5 Add Optical line to Apple TV 4 January 6, 2017 I am now able to run an optical line between the Apple TV 4 to the 5.1 sound system and now I get the full 5.1 sound and with no more audio drops. Since the Apple TV 4 does not have an optical port and my 5.1 Kenwood Audio Video VR-407 (2003) receiver equipment is old enough not to have HDMI. I had to run the HDMI directly to my Panasonic Plasma Flatscreen, TH-42PX75U (2007). Then output the optical line from the plasma back to the audio receiver. There were a couple of short comings with this configuration. The main issue was that there would be an audio drop for a second or two from time to time. I did isolate the sound issue to my flatscreen but switching to 16bit and many other varies settings did not help. The other issue was no 5.1 when I back feed the optical line from the Plasma. So the bottom line is, I have full 5.1 channels and I have my sub wolfer back. But, most importantly, no more audio drops.

I would recommend this item to a friend! Customer Videos:
