Description Saman Porhemmat 2015-11-08 19:30:44 UTC

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:

Hope this helps

Comment 1 morgan read 2016-07-17 15:59:34 UTC

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.

Comment 3 morgan read 2016-07-23 22:03:39 UTC

This bug seems (perhaps) fixed in f24, see here:
