LogiCORE HDMI RX 1.4/2.0 Subsystem IP v3.1 (Rev 2): Why is there no audio when AppleTV is playing a DolbyAtmos movie in LPCM format?


There is no audio when an AppleTV 4K device is playing a DolbyAtmos movie in LPCM format using the HDMI IP pass-through example design. 

When Dolby Atmos set to "OFF" (ie when sending 8 channels LPCM instead of Atmos), audio is either not played or is corrupted.

What is the cause of this issue?
