I had been trying to cherry-pick patches from the working Xenial kernel to mainline, and got bogged down with build issues. Back to the bisection:
This kernel ... http://kernel.ubuntu.com/~jsalisbury/lp1657994/linux-image-4.4.0-040400-generic_4.4.0-040400.201702021530_amd64.deb .. does not work. Failure mode like 4.4 mainline. I can also update that mainline kernels 4.10.3 and 4.11-rc2 both fail like other recent mainline kernels. To recap, we have only two working data points, both Xenial kernels (4.4+i915 backport). 4.4.0-59 4.4.0-21 All mainline 4.4 kernels do not even enumerate HDMI audio. All mainline kernels from 4.5-rc1 and later enumerate HDMI audio but produce no sound. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1657994 Title: Regression: HDMI audio produces no sound (Skylake NUC) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1657994/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
