Correct. The bug is with external HW decoding of HD Audio bitstreamed (not decoded) via DP->LSPCon->HDMI2.0 port to an AVR. > > mplayer supports 2 modes with different parameters.

You can test this with LibreELEC/KODI as well. I have tested this with the following Intel NUCs. All were connected to a Denon AVR-4311ci that handles the HD audio decoding. NUCD54250WYK (Haswell): HD Audio bitstream works due to native HDMI1.4 NUC5PPYH (Braswell): HD Audio bitstream works due to native HDMI1.4 NUC5i7RYH (Broadwell): HD Audio bitstream works due to native HDMI1.4 NUC6i3SYK (Skylake): HD Audio bitstream works due to native HDMI1.4 NUC6i5SYK (Skylake): HD Audio bitstream works due to native HDMI1.4 NUC6i7KYK (Skylake): HD Audio bitstream doesn't work due to Parade LSPCon NUC7i3BNK (Kaby Lake): HD Audio bitstream doesn't work due to MC2x00 LSPCon NUC7i7BNH (Kaby Lake): HD Audio bitstream doesn't work due to MC2x00 LSPCon</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> <li>You are on the CC list for the bug.</li> </ul> </body> </html>
