Amilo M6453G and ALC 880 soundchip (hda-intel)


My Siemens Amilo M6453G has a RLT ALC 880 soundchip, found as snd-hda-intel by alsaconf. But whatever I did, there was only sound over headphones, the integrated speakers didn't work at all!

Now I was successful to switch them on and I want to give a short how-to:

Here my soundchip (lspci):

00:1b.0 Class 0403: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) High Definition Audio Controller (rev 04)

The device is included in alsa-drivers (slackware-current) or in a own kernel (choose hda-intel in sound - alsa).

Run a alsaconf and then remove the lines created by alsaconf in your /etc/modprobe.conf or /etc/modprobe.d/sound (if you use udev) and replace them with

# ALSA portion
alias char-major-116 snd
alias snd-card-0 snd-hda-intel

# module options should go here
options snd-hda-intel model=F1734 position_fix=1

# OSS/Free portion
alias char-major-14 soundcore
alias sound-slot-0 snd-card-0

# card #1
alias sound-service-0-0 snd-mixer-oss
alias sound-service-0-1 snd-seq-oss
alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-8 snd-seq-oss
alias sound-service-0-12 snd-pcm-oss


The model in the Amilo M6453G is F1734. If your soundcard don't work with this model then you can change the model to one of the following and try if it will work:

ALC880
3stack 3-jack in back and a headphone out
3stack-digout 3-jack in back, a HP out and a SPDIF out
5stack 5-jack in back, 2-jack in front
5stack-digout 5-jack in back, 2-jack in front, a SPDIF out
6stack 6-jack in back, 2-jack in front
6stack-digout 6-jack with a SPDIF out
w810 3-jack
z71v 3-jack (HP shared SPDIF)
asus 3-jack
uniwill 3-jack
F1734 2-jack
test for testing/debugging purpose, almost all controls can be
adjusted. Appearing only when compiled with
$CONFIG_SND_DEBUG=y


Then add the following lines to your /etc/rc.d/rc.local:

/sbin/modprobe snd-hda-intel
/sbin/modprobe snd-pcm-oss
/sbin/modprobe snd-mixer-oss
/sbin/modprobe snd-seq-oss


After a reboot your soundchip should work fine and with amixer or alsamixer you can change the volume of "Internal Speaker".

May be this help someone who owns such a Amilo notebook.

Fluxx.
