HDMI Receiver Subsystem v3.0 - Why do I get broken Audio when playing 4K Video with Apple TV 4K or Roku Ultra?


When I use Apple TV 4K or Roku Ultra to play video in 4K HDR mode, the audio sounds broken.

What can cause the problem?


This is a known issue when the following HDMI sources are in 4K HDR mode. 4K SDR and other video modes do not have this problem.

  • Roku Ultra is playing 4Kp60 YUV 422 12bits, with audio
  • Apple TV 4K is playing 4kp60 YUV 420 10 bits, with audio

When the issue occurs, the length of some AES3 block is shorter than 192 frames.

This issue has been fixed in Vivado 2018.1 and later. 

Users should update to the latest version of the IP.

  • Vivado 2017.3 - Users can download the HDMI Receiver Subsystem platform from (Xilinx Answer 69869) to work around this issue.
  • Vivado 2018.1 - This issue is resolved in the HDMI Receiver Subsystem in Vivado 2018.1 and later.
