Sound not working LG Notebook HDA Realtek ALC883

[Gruenkohl]

Description of my Sound-Problem

I use a notebook from LG-Electronis P1-KPRBG and Linux Mint 9.

The audio device is a Intel Corporation N10/ICH 7 Family High Definition Audio Controller (rev 02) with Codec: Realtek ALC883.
It can control surround 5.1 sound, which I don't need, because 1 don't carry 6 loudspekers with my notebook.

When i use it with Windows 7, everything works fine.

When i use it with Ubuntu 10.4 or Linux Mint 9 i get sound only out of the headphones exit. And no microphone is working.

When i use it with Scientific Linux 6.2, then i get sound on the internal loudspeakers and the built in microphone is working, when i've choosed microphone 2.

I'd prefer staying with Linux Mint 9 (which seems to be a derivate of ubuntu), but at least any microphone should work, so I can use skype and twinkle.

More technical information in detail you can find under
http://pastebin.com/j5H0s6hh (The Linux Mint sound information)
and
http://pastebin.com/nu9EAdi9 (The Scientic Linux sound information)

Why does the sound work under Scientific Linux and not under Linux Mint?

Could I change anything under Linux Mint, so the sound will work as under Scientific Linux?

Btw, it works under Scientific Linux just without changing anything (except changing the microphone entry). So I don't think, that hints using alsamixer or pavucontrol can help.

I need help from somebody, who can compare the both outputs of alsa-info.sh and notices the differences and what they mean.

Some examples of differences i've found:

Linux Mint has installed also ESound daemon, which is not running.
Scientific Linux has not such an installation.

Linux Mint uses irq 22 for the soundcard;
Scientic Linux uses irq 30

In the output for Linux mint i find a section "modeprobe options"; in the output for Scientific Linux not.

In the section HDA-Intel Codec information i find by
Linux Mint "Function Id: 0x1". By
Scientific Linux this is "AFG Function Id: 0x1 (unsol 0)"

There i also found in the part "Node" on
Scientific Linux "Converter: stream=5, channel=0" and on
Linux Mint "Converter: stream=0, channel=0"

I need help from an expert who knows, what such diffences mean and not from people, who are just guessing.

You could try installing a new driver package from www.alsa-project.org.

After unpacking the tar.bz2 file of alsa-driver 1.0.25, you can right-click in the folder where you unpacked it > open in terminal. Then run these commands to compile and install the newer drivers:

Code: Select all

./configure --with-debug=full --enable-dynamic-minors --with-moddir=updates --with-cards=hda-intel
make -j2
sudo make install

Thank you, AlbertP for your answer.

I've got lots of such hint's, which are just guessing, that an update made help. I tried them all, but they didn't help.

So I still searching for answer of somebody who knows about what he talks.

Scientific has MSI enabled (that's why it has a different IRQ number). Could you try putting this in /etc/modprobe.d/alsa-base.conf?

Code: Select all

options snd-hda-intel enable_msi=1

Hallo Albert,

I did what you adviced me. But I'm sorry, that didn't change anything (as far as i could notice).

Perhaps I didn't follow your advice correct, so I post here my alsabase.conf.

The last two entries were added by me.

By comparing the Linux Mint with the Scientic linux (where the sound is working), i found, that there is no alsa.conf in etc./modprobe.d, but only a dist-alsa.conf.

CODE:SELECT ALL is just the text which appears above pieces of code in the forum, it doesn't need to be copied. The other text in alsa-base.conf shouldn't matter for you as it only applies to sound cards that you do not have. Also the name of the file does not matter as long as it ends in .conf.
