Hardware is an Intel NUC7i5BNH (Kaby Lake), latest available BIOS and latest available HDMI/LS-PCON firmware. The AVR is a Denon AVR-2310. The TV is an old Toshiba 1080p LCD. I make sure that the TV and AVR are turned on first so that EDID is available. When playing a file with HBR audio bitstreams (DTS-HD, Dolby TrueHD) I get no audio. When playing a file with EAC3/DD+ audio bitstreams, I get very regular dropouts. When I play a file with stereo/DTS/DD bitstreams, all is fine. When I play an audio file with 6 channels of LPCM, all is fine. I can play the same files with HBR or EAC3 audio on the same machine from a Windows install without any issue, right out of the box using the built-in software, using the default configs, which rules out hardware incompatibilities. I've spent some time with the Kodi guys who have come to the conclusion that the issue was not with them but higher in the software stack. So here I am! History here: https://forum.kodi.tv/showthread.php?tid=359371 I've also filed a bug with Intel, but I'm not getting any traction there. Must be the holydays! https://gitlab.freedesktop.org/drm/intel/-/issues/2861 Any help is welcomed. I'm no dev, but I know my way around Linux and systems, and I am not afraid of testing things and reporting data. Compiling code is usually something I can do, with instructions if it's less run-of-the-mill. Thanks in advance!
