Description of problem: I Installed Fedora 23 Gnome on HP Spectre x360. Everything works fine except that there is no sound! I googled and searched about this problem and realized that this is a common bug when people install Linux. I did the following and the problem is fixed now: 1. sudo gedit /etc/default/grub 2. Edit the line: GRUB_CMDLINE_LINUX="rd.lvm.lv=fedora/root rd.lvm.lv=fedora/swap rhgb quiet" and replace it with: GRUB_CMDLINE_LINUX="rd.lvm.lv=fedora/root rd.lvm.lv=fedora/swap rhgb quiet acpi_backlight=vendor acpi_osi='!Windows 2013' acpi_osi='!Windows 2012'" 3. Run this command: sudo grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg 4. Reboot TWO times and the problem should be solved. If you have Fedora 22 installed and encountering this problem, check the following link: https://bugzilla.redhat.com/show_bug.cgi?id=1220709 Hope this helps
I'm unsure 'acpi_backlight=vendor' is necessary in f24. It seems unconnected with this sound bug, but was necessary to have keyboard back-light working, but seems unnecessary for the back-light or (if it ever was) this sound bug in f24
Apart from Comment 1, can this bug be bumped to f24 please - sound still not working.
This bug seems (perhaps) fixed in f24, see here: https://bugzilla.redhat.com/show_bug.cgi?id=1350534#c13

Now working for me in f24, see Bug 1350534
Note Bug 1350534 reopened (no longer working for me f28)
