Volume control buttons (Fn-F5 and Fn-F6) not working on Fujitsu-Siemens Amilo 1505

darkduck · 09-14-2011, 06:53 PM

I have Fujitsu-Siemens Amilo Pi 1505 laptop.
It has on-board audio card Realtek HD Audio.
lspci lists it as

Code:

00:1b.0 Audio device: Intel Corporation N10/ICH 7 Family High Definition Audio Controller (rev 02)

I have tried Simply Linux, Mageia 1, Debian Squeeze and Linux Mint XFCE. Mageia does not play on this card at all. Others do play, but keyboard combinations Fn-F5 and Fn-F6 to control volume make them stuck. Usually Fn-F5 (increase volume) works OK until Fn-F6 (reduce volume) is pressed. In this case volume comes to zero, then muted and then even manual adjustment on the volume control do not help - it immediately goes down again. But sometimes otherwise - volume control comes up to maximum and nothing can take it down.
What make things worse, when this happens, whole keyboard becomes irresponsible, so I can't look at logs. The only way to fix the situation is power off by hardware button.
At the same time, Windows XP seems to understand Fn-F5 and Fn-F6 correctly.
Did anybody encounter this issue?
Below is extract from dmesg in Mageia, don't know if it helps anyhow.

Code:

hda_codec: ALC883: BIOS auto-probing.
autoconfig: line_outs=1 (0x15/0x0/0x0/0x0/0x0)
   speaker_outs=0 (0x0/0x0/0x0/0x0/0x0)
   hp_outs=1 (0x14/0x0/0x0/0x0/0x0)
   mono: mono_out=0x0
   dig-out=0x1e/0x0
   inputs:
realtek: No valid SSID, checking pincfg 0x9983013f for NID 0x1d
realtek: Enable default setup for auto mode as fallback
input: HDA Intel Headphone as /devices/pci0000:00/0000:00:1b.0/sound/card0/input7

And finally:

Code:

uname -r
2.6.38.8-desktop586-4.mga

Other systems have different kernels, for example Mint has kernel version 3.0.

strange !
If you 're connected on a lan, try to open ssh session and look what happens once your function keys are pressed.
I had a such problem with function keys too some while ago, some hot keys hang my keyboard if pressed to rapidly on session startup, the keyboard disconnection was an immediate solve.
I finally unset all shortcuts I did with hotkeys.

Great news! Thanks!
Is this fix for Ubuntu only? How can I make it work in Debian, Mageia, Fedora etc?
Will you be able to make something like short how-to for non-Ubuntu dummies?

Thanks in advance!

Hi,
Thanks for the link.
I tried to apply similar logic to Fedora 16 system I'm in now. I even managed to download the .src.rpm file and unpack it. But I could not do more - too complicated for my non-programmer brains.
Can anyone explain or maybe prepare some ready-to-use modules (rpm, deb)?

Thanks for files.
I tried to apply .deb in Debian Squeeze: dependency is not satisfiable for libmtdev1.
As far as I understand, this package is only available in Testing and Sid now.
Any options to overcome this dependency? How safe is it to install standalone libmtdev1 from Wheezy?

In the meantime, I'll try to re-pack .deb into .rpm and try in in Mageia and Fedora.

Converted .deb file into .rpm using alien.
Tried to apply it to Fedora 16 KDE, using rpm -i <filename> --replacefile.
Result - Fedora's dead. It does not respond to keyboard at all, even on login screen.

Not a big deal since I wanted to replace Fedora with smth else anyway. But less one guinea pig.
Won't test on Mageia yet.
