Description Dan Winship 2011-12-06 19:12:30 UTC
Newer thinkpads like the x220 have an LED on the keyboard mute button. However, in F16, while the mute button works correctly to mute/unmute, the LED just gets toggled each time you press the key, failing to reflect mutes/unmutes from other causes.

Eg, if the system is currently unmuted, and you press the mute button, then the mute LED will light up, and the panel will show the muted speaker icon. But if you then open the volume control in the panel and turn the volume back up, the panel will reflect the volume change, but the mute LED will stay lit. If you then press the mute button again, the volume will be muted, but now the LED will turn off.

The kernel thinkpad-acpi docs say:

  The newer Lenovo models only have firmware mute control, and depend on
  the main HDA mixer to do volume control (which is done by the operating
  system).  In this case, the volume keys are filtered out for unmute
  key press (there are some firmware bugs in this area) and delivered as
  normal key presses to the operating system (thinkpad-acpi is not
  involved).

which hadess says means this is alsa's problem

Comment 1 Fedora End Of Life 2013-01-16 14:05:03 UTC
This message is a reminder that Fedora 16 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 16. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora 
'version' of '16'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version prior to Fedora 16's end of life.

Bug Reporter: Thank you for reporting this issue and we are sorry that 
we may not be able to fix it before Fedora 16 is end of life. If you 
would still like to see this bug fixed and are able to reproduce it 
against a later version of Fedora, you are encouraged to click on 
"Clone This Bug" and open it against that version of Fedora.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

The process we are following is described here:

Comment 2 Dan Winship 2013-01-16 15:40:37 UTC
still true as of f18

Comment 4 Andrew Demas 2013-08-23 02:26:37 UTC
This issue is still valid for F19. Mute button brings up gnome help dialog.

Comment 5 Dan Winship 2013-08-23 11:29:26 UTC
This bug is just about the mute LED. If the mute button brings up the help dialog for you, that's a completely unrelated bug (and are you sure you're not just hitting F1 at the same time you hit mute?).

Comment 6 Andrew Demas 2013-08-23 14:02:53 UTC
Apologies on extending the bug. No I'm sure that I am not hitting F1. I did however go into keyboard settings and remap help to another hot key, but acpi_listen doesnt pickup an event when I hit the mute button. Shall I reference the led issue in another bug report?

Comment 10 Fedora End Of Life 2015-06-29 11:37:19 UTC
Fedora 20 changed to end-of-life (EOL) status on 2015-06-23. Fedora 20 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
bug.

Thank you for reporting this bug and we are sorry it could not be fixed.
