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)
(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.
