The problem is in the graphic drivers like nouveau and radeon. The audio side needs to detect the monitor is plugged in as well as ELD data, then the hdmi audio could work.
Since we don't have ability to change the nouveau or radeon, I will think about adding a new patch that will take care of this bug as well as #1827967. -- 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 ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
