Hi all! Just for reference, - I can confirm this annoying issue also for Kernel 5.11.0-38-generic (Kubuntu 20.04 LTS). The used Radeon hardware is quite old, the sound is listed as "RV635 HDMI Audio [Radeon HD 3650/3730/3750]".
In my case the audio started to work after I installed "pavucontrol" and then I just selected the (inactive) Radeon HDMI profil under "Configuration". That was all. The crazy thing is that the HDMI is still shown as "unplugged" but it works. And I really didn't have applied any of the above mentioned patches, - weird. ;-) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1834771 Title: No HDMI-audio after kernel 4.15.-0.50 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1834771/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
