Mute key LED does not work on HP notebooks

[Steven H]

Description of problem:
The F6/mute key on the keyboard of HP notebooks often has a built in LED indicator to show if the sound is muted. The LED state is never toggled. It will just retain its state, even though the audio is succesfully muted/unmuted.

Tested with HP Envy 15 from 2015. HP Stream 11 from 2015 and HP Stream 11 from 2016.

Version-Release number of selected component (if applicable):

How reproducible:
Always.

Steps to Reproduce:
1. Press mute key on HP laptop

Actual results:
Mute state in software toggles, LED in mute key does not.

Expected results:
Mute state in software and LED in mute key toggle.

Additional info:
This happens on kernel 4.8, 4.9 and 4.10. I have not tested any other versions.

Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem?

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.11 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

Just tested under: 4.11.0-041100rc7-generic

The problem is the same. I have always had this problem under Linux, but started using on these notebooks since kernel 4.8.

[Steven H (yakity-1)]

How can I ensure that this bug is also known to upstream? Will it get reported automatically, or will this bug just sit here and should I report it elsewhere myself?

[Kai-Heng Feng (kaihengfeng)]

Please try the kernel [1]. Note that this will only works on Envy.

Hi Kai-Heng,

Unfortunately there was no change in the behavior. Thanks for the effort though.

[Kai-Heng Feng (kaihengfeng)]

I added this quirk
"SND_PCI_QUIRK(0x103c, 0x81cc, "HP Envy", CXT_FIXUP_MUTE_LED_GPIO),"
... based on commit [1].

Since it doesn't work, please file an upstream bug.

[Benjamin Halbrock (kontakt-bennis-blog)]

I do have the same problem on a ProBook 440 G4.
There is a slider for the LED in alsamixer but it doesn't change anything.

Are there any tests I can run?

[Kai-Heng Feng (kaihengfeng)]

Benjamin,

Can you file a new bug?

[emni petro (emnipetro)]

A person necessarily lend a hand to make severely posts I would state. This is the very first time I frequented your website page and thus far? I surprised with the analysis you made to create this.
we provide teh support related to it then you can visit the site https://www.hptechnicalsupportphonenumbersusa.com/hp-customer-care/

[Andrei (andysemakov)]

I found solution which was working for me on HP Probook 450 G4: https://forums.gentoo.org/viewtopic-t-1086606-start-0.html

Concise version:
make sure there is a line:
options snd-hda-intel model=mute-led-gpio
in /etc/modprobe.d/alsa-base.conf

[Kai-Heng Feng (kaihengfeng)]

Andrei,

Please file a separate bug so we can make the change into kernel.
