here are some diagnostics i did and put it into pastebin
rpm -qa | grep -i alsa
sudo /sbin/lspci | grep -i audio
/usr/sbin/hwinfo --sound
amixer -i
lsmod | grep snd_hda_intel

->-> http://pastebin.ch/118

can't find any solution
my soundcard only works on microsoft correct. but i don't want to use this OS.

can anybody help me?

excuse my bad english

Please download and run the two scripts from this audio troubleshooting guide, and post the output URLs here, so we can get a better look at your hardware and software configuration of your Dell:

first, thank you for your fast help,

here is the alsa-info.txt
alsainfo.txt from schell script http://www.pastebin.ch/119

and here the other script
tsalsa scripthttp: http://nopaste.com/p/a44qKrNtmb

while recording i use the alsa-default setting cause best (not really) result

thanks

Thanks, I'll take a look at those ... in the mean time, to test your recording, I recommend you simply use "arecord" as opposed to an application which may or may not be configured:

I gave some info here on using "arecord".
http://www.suseforums.net/index.php?s=&amp...st&p=224829

that sounds hopefull :-)
ok i will try arecord..... first of all the man file...

my problem i'm new in linuxing :-)
but when this is a solution for my problem i'll be very happy

arecord seems to have no ogg or flac ..... and wav's to big for the night.
(listennig newsealandradio-record it and hear it next day :-) )

i will try
thank you very much!!!!!!!!!!!!!

Thanks, I took a look at those. It confirmed your Dell Inspiron 6400 has a Stac9200, and you installed openSUSE-10.3 with a bigsmp kernel (32-bit).

I notice from the alsa web page, there there were a number of updates to stac92xx in alsa-1.0.15 and 1.0.16:
http://www.alsa-project.org/main/index.php...c92xx&go=Go

Some of them are related to the mic. Hence I recommend you update to alsa-1.0.16. You can do that by typing the following commands in a konsole/xterm with root permissions (which I modified specifically for your big smp kernel):

zypper ar http://download.opensuse.org/reposit...E_10.3_Update/ multimedia-audio01**
zypper install alsa alsa-driver-kmp-bigsmp alsa-utils alsa-tools alsa-firmware
zypper rr http://download.opensuse.org/reposit...E_10.3_Update/

It may be easiest to copy and paste those lines into a konsole (one at a time).

Note the first zypper command adds a cutting edge multimedia repository (with the alsa 1.0.16 rpms). The second zypper command installs the rpms. And the 3rd zypper command removes the repos (after the install is complete), as its not always a good idea to have a cutting edge repos in one's active repos list.

Reboot (restart your alsa) after updating, and then try your sound and your mic again. If that doesn't work, you may need to try one of the following options in your /etc/modprobe.d/sound file (this is from your ALSA-Configuration.txt file that is on your PC):

****STAC9200
******ref********Reference board
******dell-d21****Dell (unknown)
******dell-d22****Dell (unknown)
******dell-d23****Dell (unknown)
******dell-m21****Dell Inspiron 630m, Dell Inspiron 640m
******dell-m22****Dell Latitude D620, Dell Latitude D820
******dell-m23****Dell XPS M1710, Dell Precision M90
******dell-m24****Dell Latitude 120L
******dell-m25****Dell Inspiron E1505n
******dell-m26****Dell Inspiron 1501
******dell-m27****Dell Inspiron E1705/9400
******gateway****Gateway laptops with EAPD control

You need to restart your alsa after each attempt with the different options (try only one at a time).

There are instructions on how to do that edit to the /etc/modprobe.d/sound file here:
http://en.opensuse.org/SDB:Intel-HDA_sound_problems

My general reference for this is the audio troubleshooting guide here:
http://en.opensuse.org/AudioTroubleshooting

Good luck, and please keep us appraised of your progress.

thank you very much
i will try this and will keep you appraised of my progress.

hello oldcpu,

first of all i installed the newest alsa driver as you recommended.
then i tried all the posibilities .... first like...

#options snd-hda-intel enable=1 index=0 position_fix=2
#options snd-hda-intel enable=1 index=0 model=ref position_fix=0
options snd-hda-intel enable=1 index=0 model=ref position_fix=1
#options snd-hda-intel enable=1 index=0 model=ref position_fix=2
#options snd-hda-intel enable=1 index=0 model=dell-d21 
#options snd-hda-intel enable=1 index=0 model=dell-d22 
#options snd-hda-intel enable=1 index=0 model=dell-d23 
#options snd-hda-intel enable=1 index=0 model=dell-m21 
#options snd-hda-intel enable=1 index=0 model=dell-m22 
#options snd-hda-intel enable=1 index=0 model=dell-m23 
#options snd-hda-intel enable=1 index=0 model=dell-m24 
#options snd-hda-intel enable=1 index=0 model=dell-m25 
#options snd-hda-intel enable=1 index=0 model=dell-m26 
#options snd-hda-intel enable=1 index=0 model=dell-m27 
#options snd-hda-intel enable=1 index=0 model=gateway 
# u1Nb.dMH6nFzhrH7:82801G (ICH7 Family) High Definition Audio Controller
#alias snd-card-0 snd-hda-intel

allways with a restart "rcalsasound restart" and putted the mixer options to high (capture)

then i did i like :here is described:http://alsa-project.org/main/index.p...dule-hda-intel

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

# module options should go here

options snd-hda-intel enable=1 index=0 model=ref position_fix=1
#options snd-hda-intel enable=1 index=0 model=ref position_fix=2

#options snd-hda-intel enable=1 index=0 model=gateway 
# u1Nb.dMH6nFzhrH7:82801G (ICH7 Family) High Definition Audio Controller
#alias snd-card-0 snd-hda-intel

# 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

with all the possibilities too.
but it do not work at all

i did it with every possibility ... but it won't work....
i did it 2 times cause first the user was not in the audio-group :-)
do you have any another ideas with wich i could fix my problem?


thank you
martin

first of all i installed the newest alsa driver as you recommended.[/b]

ok, great. To confirm that was successful, can you post the output of:
<span style="font-family:Courier New">rpm -q alsa alsa-driver-kmp-bigsmp alsa-utils alsa-tools alsa-firmware</span>

then i tried all the posibilities .... first like... [/b]

I hope you understand the syntax of the code you applied. Did you deliberately apply # in front of each option (to comment it out) and then selectively remove for each test? If so, it appears you commented out the line starting with "alias ....". You should not have done that. It should be present (and not commented out) for each test.

then i did i like :here is described:http://alsa-project.org/main/index.p...dule-hda-intel [/b]

OK, this is good, but again, it looks to me like you are innovating on your own here. Or have I misinterpreted? If you are going to apply your own innovation, you need to be VERY VERY VERY exact.
