@hui.wang: The problem continues with kernel 5.11.0-41-generic and the driver radeon, that doesn't support audio components yet. Is easy to see that ELD was not intended for the Radeon driver and implement it by force will probably never happen as we can see here:
http://lists.freedesktop.org/archives/dri-devel/2019-July/227423.html Please, apply a patch at the Ubuntu level to disable the check of eld_valid for the Radeon driver, because is clear that this will never be fixed in the upstream!!! -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1834771 Title: No HDMI-audio after kernel 4.15.-0.50 Status in linux package in Ubuntu: Confirmed Bug description: I've got no HDMI-audio.
