I can confirm solution in #19 works. Only caveats: 1) Rename `/root/` occurrences to `/usr/local/bin/` 2) Screens flickers on/off a couple/few times during boot.
My platform has nVidia GTX 970M hardwired to built-in HDMI hooked up to external TV. Intel Skylake HD530 graphics controlling laptop built-in display and USB-C Thunderbolt3 DisplayPort with HDMI adapter to 2nd external TV. Everything works seamlessly in Windows 10 and I'm glad the patch in #19 gets things one step closer to working in Linux/Ubuntu 16.04. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1377653 Title: HDMI sound output not detected / NVIDIA optimus laptop To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1377653/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
