Tried all this stuff on latest Ubuntu 10.10 and Elitebook 6930p. Most of
these problems went away already. Here is what still doesn't work for me
very well:
1. Hardware mute button actually mutes/unmutes internal speakers though
sound mixer applet is not updated properly. Though when
I have not been able to resolve the mute issue on a 6730b, but I did
find a nice workaround, which is setting a keyboard shortcut to control
mute for my laptop. In my case, I set Ctrl+~ as mute, and it works fine.
So, that's a bridge between the hardware and software mute, but the

Hi Guys,
If there doesn't already exist an upstream bug report, it might not hurt
to open one at bugzilla.kernel.org if you still experience this issue
with the most recent mainline kernel. There are mainline kernel builds
that you should be able to test with at the following:
Hmm, looks like some progress is being made on the Mute-LED front.
http://groups.google.com/group/linux.kernel/msg/d71c68275456957a
As I discovered when testing the 2.6.31-rc2-based kernel, this fix
applies only to the 'mobile' model (which lacks the second capture
stream and the dock inputs),
Now I've figured out a bit more about the GPIO usage:
GPIO 0 (input) acts as headphone detection -- 0 if present, 1 if absent.
GPIO 1 (output) controls muting and LED -- active high ('1' mutes).
GPIO 2 (input) returns LED status (pressing hardware button toggles it) --
active high.
It seems ALSA
hmm, it looks like the FDI file has been fixed in hal-info git.
http://cgit.freedesktop.org/hal-info/tree/fdi/information/10freedesktop/30-keymap-hp.fdi
The unable to handle keycode bug seems like this one -- just finally marked
as being worked on... today:
ANother new thing I noticed: after installing (and fixing) HDAAnalyzer, as
shown here, I was able to confirm that asserting GPIO 0 on the adi1984 chip
sets the hardware mute feature.

Relevant lines from Windows .inf file:
Correction: I meant GPIO 1.

I have an EliteBook 8530w (with ATI card, not nvidia), and have many of

fine. Although the brightness hotkeys work in gnome after I run

Today's update which included new versions of the gnome-power-manager

Not sure why it say 7.15 here and 8.17 in uname. The latter is correct.
It's a custom kernel, the only change is enabling 64G. Running the
default kernel makes no difference.

mute, brightness buttons on
The brightness problem persists. There are at least three events that should
change the brightness of this machine's screen:
- Function keys Fn/F9 and Fn/F10
- Gnome Brightness Applet
- Connect/Disconnect A/C Power
All three have the same results:
- A pop up on the screen indicating brightness
Thanks Matt.
Sound works now for me as well. The hardware mute button and the
software mute button work independently, i.e. if you press one, the
status change isn't reflected in the other one. Furthermore, the
software mute has precedence over the hardware mute. Not perfect, but
much better than

Updated the laptop to 8.10RC and got the hardware mute switch repaired.
The original problem description is updated accordingly, and the
rephrase posted above can be ignored.
I don't seem to be the only one who has no sound on the speakers:

Let me try to rephrase the audio problem.
The machine has three physical controls: volume up, volume down and
mute. It also has an LED indicating the mute status. Gnome and Vista
have a master volume slider and a mutton button on their GUIs. Normally,
any action on a physical control is reflected
