[solved] snd_hda_intel problem with ALC880 in laptop

I'm having problems with my laptop soundcard. It's a ALC880 chip and lspci reports:

00:1b.0 Audio device: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 02)

My problem is, that I cannot get the laptop speakers to play any sound. If I plug headphones to my laptop the headphones work just fine.  I've tried alsamixer and there is no Master channel to unmute like in the Wiki articles advice. Also if I rmmod the module and reload the PCM also disappears. I've tried adding:

options snd_hda_intel model=laptop

to modprobe.conf but that didnt help at all.

I started using Archlinux only a few days ago and I dont have much experience with linux, but I do have about 20 years of experience with windows & pc so I'm not a total "lost cause"

Thank you for any advice you can give me and if you need more data from my system just tell me what to do.

As root

gpasswd -a <username> audio

Logout, log back in, trun the volume up!

Oh, maybe not if your headphones are working... In your sound mixer (e.g.) gnome, is the master volume turned up, could be something todo with your DE mixer.

Yes the user is in audio group allready. The sound did not work before or after installing a DE (KDE) unless using headphones.
And as I mentioned in my post there is no master slider in alsamixer or in kmix. There are only:

in kmix:
Output:
PCM    Front    Front Mic    Line

Input:
Capture    Capture    Capture

Switches:
Headphone    IEC958(turned off)    Caller ID(turned off)    Off-hook(turned off)

The laptop is LG P1 Express dual.

My stepbrother has sound issues on a intel soundcard for a laptop, mine works fine, no issue.

I suppose you could try using OSS, see if you can get that working.

Found the problem.. I had to download alsa sourcecode and take a peek in the patch_realtek.c file to see all the possible "model" params.. and surprise surprise, there was one of LG so editing the line in modprobe.conf to "options snd_hda_intel model=lg" got things working.
