No sound even when I turn everything up to max

I looked at the script output, ... and I note the Intel codec is an AD1984. Searching the alsa page I find support for this has only very recently been added:

If you are unlucky, support for yours may need alsa-1.0.15.

But somethings we could investigate ... can you type:
dmesg > dmesg-record.txt and then open "dmesg-record.txt" in a text editor and do a search for error messages associated with the key words "alsa", and "intel" and "snd" and maybe anything else you think relevant.

If in the dmesg you see a message about alsa firmware not being installed, you check if alsa-firmware & alsa-tools are installed, and if not, install them. Then try rebooting. (maybe also try running "alsaconf" to configure your sound).

I note your audio levels are at 100%. If you do get sound working, that will cause distortion. Be sure to back off to 75% or so. I note "simple mixer control speaker" is OFF. Did you try the ON setting (honestly - I don't think that has anything to do with this, but I am trying to be thorough).

If the above doesn't work, you may have to try and upgrade to the RC version of alsa-1.0.15. Either download and compile and build your own alsa, alsa-driver, alsa-firmware, alsa-tools,
http://www.alsa-project.org/main/index.php/Download

... or download and install rpms from this site:
http://download.opensuse.org/repositories/...SUSE_10.3/i586/

I've never tried using that site, so I don't know how good or bad the quality of those rather cutting edge rpms are.

Are you by chance using a Thinkpad laptop? If so, this URL may be relevant to you:

Actually, now things seem to work.

What happened was that I made my first post, then I quit suse and went to vista to do stuff. After I saw the replies I booted back into suse. Before it even got to the login screen, I was greeted with a continuous LOUD ear-piercing BEEP, but curiously, the startup sound played as the desktop loaded up, even though it was distorted. I just had to disable "internal mic" in order to get rid of the beep, and now sound seems to work fine around 70% volume.

I'm a total newb at Linux. I messed around with Ubuntu on Wubi then decided to try out OpenSuSe after hearing some good things about it.

Sorry about the false alarm, haha..

There's still something I'm wondering though.. Why is it that full volume result in distorted sound?

Congratulations, glad to read it is working.

Gosh, this is something I learned from the "school of hard knocks", as opposed to the one of theoretical science.

ie by playing with the levels, and by reading about the experience of others, I discovered that 100% isn't best.

I assume its because at 100% one is slightly over driving the corresponding analog amplifiers within the sound card/chip into a non-linear range, ... but in truth I really don't know.

same problem here, I test new alsa from BuildService and also test ubuntu trick https://bugs.launchpad.net/ubuntu/+bug/122560

No success. So bugzilla.novell.com #371050

Hope Takeshi will now what to do

From the bug report you quote, it appears your sound works:
https://bugzilla.novell.com/show_bug.cgi?id=371050

Is that you on the thread? If not, I really can't tell what you tried.

Did you install alsa-firmware? Did you try yast? alsaconf? edit your /etc/modprobe.d/sound with various options? ....

How about trying to work your way through the audio troubleshooting guide:
http://en.opensuse.org/AudioTroubleshooting

... and if nothing else, post the output URL from the two diagnostic scripts:
http://en.opensuse.org/AudioTroubleshootin...led_information
... such that we can check if you made a mistake in your configuration/setup.

Also, it would help if you posted here the contents of your /etc/modprobe.d/sound file.
