Description of problem:
Installation succeeds on HP Spectre x360 (model 13-4003dx) without issue, 
except that sound will not work on the internal speakers.

The GNOME sound settings UI will show an empty list of sound devices.
When an external device is connected (for example, a Bluetooth speaker),
sound works perfectly on the external device and the device indeed
becomes listed in the GNOME sound settings UI.

When attempting to adjust the sound volume in GNOME with no external
speakers connected, the indicated sound device is "HDMI/DisplayPort".
However, no sound is ever produced on the internal speakers.


Version-Release number of selected component (if applicable): Fedora 21, Fedora 
22 with latest kernel (4.0.2)


How reproducible: Happens 100% of the time.


Steps to Reproduce:
1. Install Fedora 21 or 22 with any kernel up until the latest (4.0.2)

Actual results:
Sound will not work on internal speakers and no sound interface will be shown 
in GNOME settings. Sound will work on external Bluetooth speakers or headphones.


Expected results:
Sound is expected to work on internal speakers.


Additional info:
This appears to be a bug that is common across all new laptops shipping with 
the new Broadwell-U chipset. It has already been reported (and apparently 
resolved in a kernel update) for the Dell XPS 13 which ships with the same 
chipset [1] [2] -- however, the fixes described therein do not aid with the 
Spectre x360. A bug for the Spectre x360 is also currently open over at 
Ubuntu's bug tracker [2].

I can add that this issue remains present when upgrading to the 4.1-rc3
kernel via the rawhide repositories.

I also have a HP Spectre 360, and while collecting info to file bug
1222273, I noticed this recurring message in journalctl:

kernel: broadwell-audio broadwell-audio: ASoC: CODEC DAI rt286-aif1 not
registered

Searching for that codec name brought me to
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1413446

In my case, the internal speakers are working fine, but the builtin
microphone doesn't work (which matches the systems some folks have
reported on that Ubuntu bug).

On closer inspection, it appears the audio on my system is actually
coming out via the currently attached external monitor's speakers over
HDMI, rather than using the internal audio.

Together with bug 1221050, this suggests to me current drivers may have
significant compatibility issues with this particular chipset.

It would be pretty neat if someone could help out with this. It seems to
be a common issue with Linux distributions and the Broadwell-U
chipset...

Hi All,

I was able to get this working on my HP Spectre x360 on Fedora 22 as
follows:

1. Update grub config
 
# vi /etc/default/grub
GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR="$(sed 's, release .*$,,g' /etc/system-release)"
GRUB_DEFAULT=saved
GRUB_DISABLE_SUBMENU=true
GRUB_TERMINAL_OUTPUT="console"

   Before:
          GRUB_CMDLINE_LINUX="rd.lvm.lv=fedora_spectre/swap 
rd.lvm.lv=fedora_spectre/root rhgb quiet"

   After:
         GRUB_CMDLINE_LINUX="rd.lvm.lv=fedora_spectre/swap 
rd.lvm.lv=fedora_spectre/root rhgb quiet acpi_backlight=vendor 
acpi_osi=`!Windows 2013` acpi_osi=`!Windows 2012`"

GRUB_DISABLE_RECOVERY="true"

[root@spectre ~]# grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg

2. Reboot 2x

FWIW - I did not encounter this on my Lenovo x230. The underlying issue
appear to be how Broadwell-based chipsets are recognized.

On the HP forums, folks noted that the backlight parameter was also
required. This did appear to be the case for me as well - if I left it
out, the sound worked fine but the screen dim/bright control did not.

Hope this helps!

After changing the backticks in Mark's workaround to single quotes, that
configuration change did the trick for me - the on-board speakers and
microphone in the Spectre 360 are working for me for the first time
since I got it.

The two reboots appear to be needed - after the first reboot, the
onboard audio still wasn't recognised, but it was there after the second
one.

*********** MASS BUG UPDATE **************

We apologize for the inconvenience.  There is a large number of bugs to
go through and several of them have gone stale.  Due to this, we are
doing a mass bug update across all of the Fedora 22 kernel bugs.

Fedora 22 has now been rebased to 4.2.3-200.fc22.  Please test this
kernel update (or newer) and let us know if you issue has been resolved
or if it is still present with the newer kernel.

If you have moved on to Fedora 23, and are still experiencing this
issue, please change the version to Fedora 23.

If you experience different issues, please open a new bug report for
those.

As far as I am currently aware, the workaround Mark listed above is
still needed to get audio working on the Spectre 360.

Rechecking that will require removing the workaround, rebooting and
seeing if the audio keeps working (so the needinfo flag is still valid).

Can confirm:

1) f23 does not have sound
2) went through Mark's steps but changed from backticks to normal apostrophes
3) reboot x2
4) sound!
5) commented out change/re-ran grub2-mkconfig
6) reboot x2
7) no sound!
8) repeat steps 2-4

I can confirm that the following did indeed work for me on a fresh
installation of Fedora 23:

1) Fedora 23 has no sound.
2) Appended the following string to the GRUB_CMDLINE_LINUX parameter in 
/etc/default/grub: acpi_backlight=vendor acpi_osi='!Windows 2013' 
acpi_osi='!Windows 2012'
3) Note that Mark's string used backticks instead of single quotes and thus did 
not work.
4) Ran this command as root: grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg
5) Rebooted twice.
6) Sound still did not work immediately. I had to open Sound settings and 
select the newly discovered "Speakers - Built-in Audio" device.
7) Sound works great! Hurray!

Thanks for helping debug this, everyone. I hope this fix will be
incorporated into future Fedora updates by default.

@Nadim - is that a matter of this working by default now, or only with
the post-install grub config change?

I'm unclear of the status of this bug - Comment 11, it's been closed current 
release as of 2016.03.20, which would suggest f23.  But sound continues to fail 
similarly in f24: Bug 1279238
And, re Comment 13, is Redhat refusing this bug against Fedora?
If the former, it should be re-opened re Bug 1279238 and that marked a dup of 
this.
If the latter, that's a novel position for Redhat to take, could some 
clarification be given re bug policy - and Bug 1279238 should perhaps be 
similarly closed?

thanks

The reporter chose to close the bug, though the solution referred to is
more of a workaround than a fix.

Bastien is saying that this is an upstream bug, so it should be filed
(and hence fixed) upstream. There's nothing terribly novel about that,
it happens all the time; Fedora has a stated policy that fixes should
happen upstream where possible, not by downstream patching.
