The fixes in the 4.20-rc kernels are for other laptops, not the UX391UA. You'll need to add:
SND_PCI_QUIRK(0x1043, 0x10a1, "ASUS UX391UA", ALC294_FIXUP_ASUS_SPK to /sound/pci/hda/patch_realtek.c to get sound working on this laptop. I used the 4.19.9 kernel, applied the 3 linked patches and added the line above. If you're using 4.20-rc6 / 7, you may only need to add the line to patch_realtek.c -- 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
