Mute key led not working anymore

Bug #44066 reported by Lynoure Braakman on 2006-05-10
Affects Status Importance Assigned to Milestone
linux-source-2.6.15 (Ubuntu)

Bug Description

After the latest kernel upgrade (21->22) my mute key led hasn't worked, the key itself luckily still works otherwise.

Other leds and hotkeys work normally.

Daniel, this is probably where we've failed to get a patch upstream and it's then been lost when merging from there?

You should get appropriate action by unloading snd_intel8x0 then reloading it with ac97_quirk=hp_mute_led as such:

1) Quit all applications using sound (``lsof /dev/dsp* /dev/snd/*'')
2) Unload snd_intel8x0 (``sudo modprobe -r snd_intel8x0'')
3) Reload snd_intel8x0 (``sudo modprobe snd_intel8x0 ac97_quirk=hp_mute_led'')

The solution applied for bug #41015 clashes with this one, because the subvendor and subdevice ids are identical. I'm not familiar with an easy way to resolve this, since regardless which setting we use for default, _some_ model will not have intended functionality.

HPs need both mute_led and hp_only. We used to have a quirk that provided both - has that vanished?
