I have the issue as well. I have a dual boot system with following. Zenbook UX490UAR Ubuntu 18.04.1 Windows 10
I think this is due to windows not properly shutting down and holding on to a hardware device, although not sure how. Managed to resolve by a full shutdown. i.e. go to shutdown on the windows start menu and hold shift while pressing restart. A screen will appear where you can select to shutdown. After the restart and logging into ubuntu, sound works . For the volume control related bug, there was a guide here : https://askubuntu.com/questions/906303/volume-control-on-asus-zenbook-3 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1784485 Title: [ZenBook S UX391UA, Realtek ALC294, Mic, Internal] No sound at all To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1784485/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
