Need Help.... No sound from laptop speakers

hello guys .i installed opensuse 10.3 in my laptop DELL 1420 recently....but the problem is there is no sound from LAPTOP SPEAKERS which are sigmatel speakers....important to note is i am getting sound when external speakers or headphones are connected....i am using gnome.
please help me regarding this.....thanks .

My guess is you need to update your alsa version, and then possibly add a "dell specific" entry into your /etc/modprobe.d/sound file.

I recommend you start by updating your alsa version on your laptop. Please follow the openSUSE audio troubleshooting guide here:
http://en.opensuse.org/AudioTroubleshootin...ng_alsa_via_rpm

Note that dependant on your kernel version, the zypper commands may need to be different. For example, if your kernel version is 2.6.22.17, you can use the zypper commands from that guide, which are (copy and paste and execute them from an xterm/konsole with root permissions when connected to internet):

zypper ar http://download.opensuse.org/reposit...E_10.3_Update/ multimedia-audio

zypper install alsa alsa-driver-kmp-default alsa-utils alsa-tools alsa-firmware libasound2

zypper rr http://download.opensuse.org/reposit...E_10.3_Update/

Each of the above code quotes are 1 one line

You can determine what kernel version you have by typing:

uname -a

If after updating your alsa (and rebooting) your internal speakers still don't work, post here, with the output of:

rpm -qa | grep alsa

cat /etc/modprobe.d/sound

And post the URL outputs provided by the two scripts from the opensuse audio troubleshooting guide.

I added the repository and added some alsa drivers but of no use. tha out puts are....

did i commit any mistake in installing required drivers..thanku..

It looks to me like you deviated from the instructions? If you do decide to deviate, please ensure you understand what you are doing.

Those commands I gave were not to just "add the repository and add some alsa drivers". Those commands were specifically picked to:
a. add the repository, and
b. add some very specific alsa packages, and
c. remove the repository.
You did not do that, and if you deviate, and if you do not understand what you are doing when you deviate, the likelihood is your speaker sound will still not work. .... Please try to follow the instructions. If they are not clear, then please ask for clarification.

mohanvarma@mohanvarma:~> rpm -qa | grep alsa
alsa-utils-1.0.14-27
alsa-1.0.14-31[/b]

These are the wrong versions. This suggests to me you did not follow the installation instruction as provided. Plus, I don't see alsa firmware, nor alsa tools.

alsa-driver-kmp-bigsmp-1.0.16.hg20080426_2.6.22.17_0.1-1.1
alsa-driver-kmp-default-1.0.16.hg20080426_2.6.22.17_0.1-1.1[/b]

Why did you install both of these? Where did you get that from? You should NOT install both the "bigsmp" and the "default" at the same time. You should only install the appropriate version.

What is the output of:
<span style="font-family:Courier New">uname -a</span>

Yes, you made some mistakes. If you do decide to deviate, please ensure you understand what you are doing.

the kernel information is..
Linux mohanvarma 2.6.22.5-31-bigsmp #1 SMP 2007/09/21 22:29:00 UTC i686 i686 i386 GNU/Linux

and i pasted evey code u have given in terminal finally a repository is added after these instructions.it showed me lot of packages and i dont know what are need to be installed...
sorry for the trouble...

The difficulty is you have a "bigsmp". Thats a key piece of information, that was not mentioned in your earlier posts. That is not a "nominal" kernel, but is specific for PCs with large amounts of RAM.

If you read the audio troubleshooting guide that I quoted, it specifically notes for "bigsmp" you should not install the "alsa-driver-kmp-default" rpm, but ONLY install the "alsa-driver-kmp-bigsmp" instead. You should remove the "alsa-driver-kmp-default".

Because you have the mixed (two) alsa drivers, the other alsa apps failed to install. Hence after removing "alsa-driver-kmp-default", try again to install alsa-firmware and alsa-tools. So AFTER you have removed "alsa-driver-kmp-default" (and you must remove that) you can try:

zypper ar http://download.opensuse.org/reposit...openSUSE_10.3/ multimedia-audio-bigsmpoldkernel

zypper install alsa alsa-driver-kmp-bigsmp alsa-utils alsa-tools alsa-firmware libasound2

zypper rr http://download.opensuse.org/reposit...openSUSE_10.3/

rpm -qa | grep alsa</span></span>
so I can see what you have installed.

Also, WHY are you using a "bigsmp" kernel? How much RAM does your laptop have?
