Pending resolution of the bug I found an accidental solution... I don't know if it helps bug resolution.
Since I don't have any Output Card listed in Audo Settings, executing alsa_setup.sh (from http://www.stchman.com/alsa_update.html) it create permanently a new "Dummy Output", obviously not working. Then running these commands audio from speakers is working until shutdown: sudo modprobe snd-hda-intel sudo alsa force-reload <--for 3 times but waiting 10-15 seconds between one and the other This is a very strange workaround, but it work for me! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1525554 Title: [HP ProBook 470 G3, Intel Skylake HDMI, Digital Out, HDMI] No sound at all To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1525554/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
