Hi all, I have been searching the threads, posts and doing some other research to figure out my question. Since the ATV is out and I'm sure someone has tried this I figured now is a good time to open a thread. Has anyone tried using a HDMI audio extractor that breaks out optical audio with the Apple TV 4? Does 5.1 Dolby Digital get passed on to the Optical extractor? Or does it default to a stereo signal? I'm concerned that the Dolby Digital Plus signal does not contain a Standard DD 5.1 signal that was present on the last generation ATV, because in the Dolby Spec it's up to the manufacture and content provider to continue backward compatibility. In addition, people using the Roku 3 and a HDMI extractor have noted that DD+ apps like netflix default to stereo when sensing the HDMI extractor, sometimes sound is completely gone. Anyone who has tried the Apple TV 4 with an extractor please chime in! If not some healthy discussion about workarounds or if the optical audio port will make a return on ATV 5 (kinda how Roku caved and brought it back on the Roku 4) would also be appreciated! Thanks Everybody!
