Hi to all.

lspci -nn | grep -i audio
00:1b.0 Audio device [0403]: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller [8086:27d8] (rev 02)

I have some problems with that soundcard.

1) When booting I get the following error:

kobject_add failed for pcspkr with -EEXIST, don't try to register things with the same name in the same directory

2) Cannot change volume using Fn + F11 and Fn + F12 keys; cannot mute using the Fn + F10 key. When I press them I can see an icon as muting/unmuting audio and moving a slidebar as varying volume but actually audio still plays the same way: actually it doesn't mute/unmute nor changes volume. I can do change volume using the Volume Control applet or alsamixer.

3) Ekiga gives the following error when testing sound using Configuration Druid:

Failed to open the device

Impossible to open the selected audio device (HDA Intel) for playing. Please check your audio setup, the permissions and that the device is not busy.
In this case I0ve tried to kill -9 pulseaudio and redo the audio test but nothing changed.

I've been trying to modify /etc/modprobe.d/alsa-base adding and un-commenting respectively those last lines in bold character but I still have those problems.

Can't help on points 1 and 3, but I have had fun and games with laptop Fn keys before. Do you know if FN keys are supported out of the box by your distro on this laptop? Do any of the other FN combos work? If it isn't (or you don't know) then it might be that you have to fiddle about with keymappings to get it working.

For example, to get the volume FN shortcuts working on my old Sony, I had to add the following lines to the file .Xmodmap:

keycode 174 = XF86AudioLowerVolume
keycode 176 = XF86AudioRaiseVolume
keycode 160 = XF86AudioMute

This was under Xubuntu, Feisty. IIRC there was some software you could run that would show the keycodes produced by each keystroke, enabling you to capture the codes you need and assign functions to them.

I very much doubt that the keycodes above will be the right ones for your hardware, but maybe it will be enough to start you down a productive path of googling..?

Good luck!

Any other alternative?
Thanks.
