@lestcape, thanks for your upstream work toward a permanent fix. Excellent job there documenting the history of this bug. Since there was a bugless time, it seems that diffing the code from then with current would painlessly reveal the trigger. While it's there for the fixing, the trick seems to be in getting the right person (or people) to take a look.
Meanwhile, startup scripts on our local machines call the workaround on every boot and HDMI audio works. Sometimes it's broken on resume-from- suspend, then re-running the workaround script re-fixes it -- or not, depending on the current kernel, but it always works on reboot. -- 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
