I have an HP Pavilion dv5 and Opensuse 11 with dual boot (windows and linux)… When I try to disable the sound using the hardware switch, it does, but when I try to reenable it it doesn’t work… it shows the same image that I get when I try to disable the sound… The only way to reactivate using switches is to press vol +… I have the lastest kernel and the lastest BIOS upgrade… Sorry for my bad english… you know, I’m not English 
Any idea?
edit2: I’m a newbie, so please explain me easily how to solve the problem

Hello Byteater and welcome to the openSUSE forum. So, your problem is very hardware specific yet you did not state the exact HP model that you have according to the following link I found.
HP Pavilion DV5 (PUMA) - Gentoo Linux Wiki
Further, the present stable release of openSUSE is at 11.4 with the next version, 12.1 in beta release. Version 11 was release on or about June 26, 2008 , if you are really using that version it has been out of print for a while now. Finally, without any more verbal flogging lol!, consider the man that went to the Doctor saying that every time he held up his arm high, it hurt, the Doctor said, then don’t do that. Most of us don’t have volume control on/off switches. I suggest you simply don’t turn off the volume and use the software mute control instead.
Thank You,
Notebook HP Pavilion dv5-1144el
This is the real model… I know that my laptop is windows optimized by HP so there is nothing to do… 
Thank you for your help
openSUSE 11 is NOT specific enough. Supported levels are 11.2, 11.3 and 11.4. Please state clear which one you use.
Alsop stating: “When I try to disable the sound using the hardware switch, it does, but when I try to reenable it it doesn’t work…” is not enough to give us an idea about what you are doing. Trying to disable sound could even be done by throwing the loudspeakers out of the window ;). Please always tell what you are doing, what happens then and how that differs from what you thought that would happen. Precise andd exact. We are not clairvoyant.
I’m so sorry… Now I have the lastest release (11.4)… This is what happen in windows:
I tap on the hardware switch–> if the sound is enabled(the led in the switch is white), the audio becomes disabled, and the led turns red… If I retap on it, it turns white again and the audio becomes active… And here is the problem… when the led in the switch is red (means sound disabled) there is no way to reactivate it, the led is always red and the only way to reactivate the sound (using only hardware switches) is to press vol + (it’s another hardware button)… Then the sound becomes active… if I turn the sound on/off through the indicator in the panel, I have no problem…

Those kind of buttons are part of the so-called wmi (for Windows Management
Interface) protocol and are just another handicap placed on us by Redmond. You
need to file a bug with bugzilla.kernel.org to get it fixed in the kernel. It is
not an openSUSE problem. Note: The computers at kernel.org are down while they
diagnose and fix a penetration problem, thus you will not be able to file that
bug just yet. In the menatime, use the GUI and keep away from the switch.
