kubuntu: volume buttons controlling "Headphone" volume

[janl]

Binary package hint: kmix

Hi,

Running kubuntu 7.10, but this has been present at least since 7.4. On my Fujitsu Siemens S7020 lifebook laptop the volume and mute buttons send x86volume* keypresses. Under kubuntu pressing one invokes kmix (or so it appears) and a little on screen volume indicator appears mid screen. kmix is version 4:3.5.8-0ubuntu1.

Unfortunately kmix controlls the "headphone" volume (with 5.10 or 6.4 there was no "headphone" volume, and the buttons controlled some other volume slider, but also the headphones did not work). And it does not appear that it is possible to reconfigure kmix. Also, if I try to rebind the volume buttons to the "sound mixer" dock applet via global shotcuts to the PCM mixer the original (and invisible) bindings to the kmix application trumps this. Looks like these bindings are hardwired somewhere.

So I've not found any configurable way to work around this.

This is my sound hardware:

00:1b.0 Audio device: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) High Definition Audio Controller (rev 04)
        Subsystem: Fujitsu Limited. Unknown device 1326
        ...

Alsamixer identifies it as a "HDA Intel" and "Realtek ALC260".

That's interesting. The new global bindings worked after restarting my X server. In KDE I'm used to them working at once. I guess the global bindings bound/captured the keys before the hardwired place could get to them?

I think the better solution for this would probably be that the x86audio*volume (not x86volume* as I wrote above) buttons were bound in a normal way visible in global shortcuts, so that kde could tell me that the keys are already bound, and would I like to rebind them to this new function?

Kmilo, the program which handles the shortcuts, sends a dcop call to kmix to change the volume of the master channel. You can set the master channel to whichever channel you want by doing the following: right-click on kmix icon->select master channel

Indeed, so you can. But why not from the main window too?
