Summary:                    Laptop volume control & mute buttons don't work
Description: 
The Compaq, like may laptops, comes with buttons to increase and decrease
volume, as well as a mute button. Under Linux these buttons do nothing.
The mute button is always lit even when sound is coming out. The volume
control buttons do not adjust volume.

Usually these buttons are controlled over ACPI.
In some cases, you can get a key event in X server, then you can configure
the window manager to do the right thing.

Anyway, this is not a bug or a missing feature of the sound driver.

This was not filed as a bug. It was filed as a feature request. Please do
not be so dismissive. What did you spend? Maybe 3 seconds and then blew it
off?

Under Windows the buttons control volume. Pushing the buttons raises or
lowers volume in the applications. you can see the volume controls go up
and down. 

Why should Linux *not* work this way? I am requesting that Alsa consider
how to be more user friendly. I am not filing a bug report. 

If they are already handled under ACPI (which I do not use on my laptop as
it causes kernel timing problems) then please simply state that Alsa
already handles this. However, I do not beleive that these specific
buttons are handled by ACPI, but that's just my guess.
