sound not working after upgrading


My sound worked fine with Slackware 9.1 and the 2.6.7 kernel, but after upgrading to Slackware 10.0 which uses the 2.4.26 kernel, I can't get it to work. For some reason alsaconf can't find my sound card.

I'm only using the stock kernel, and it worked fine in the 2.6.7 kernel, I'm also using AC97 which is one of the most popular soundcards. I'll post as much information as I can and hopefully someone can help.

After running alsamixer:

Code:
bash-2.05b$ alsamixer

alsamixer: function snd_ctl_open failed for default: No such device
Here's my /sbin/lspci:

Code:

And when I run KDE it says something about not being able to start sound because device /dev/dsp isn't there.

Let me know if you need me to post anything else.

I don't see how - I haven't configured anything for it to be misconfigured. I have the stock kernel and didn't mess with anything to do with sound before doing this.

Sorry, I should have said I installed Slackware 10 from scratch rather than saying I upgraded it. I could understand there being some misconfiguration if I upgraded to 10 over the top, but I installed from the CDs from scratch.

well, you should probably check http://www.alsa-project.org/ ... find a setup-howto for your soundcard, go through it and see if anything is missing in your config, like in /etc/modules.conf.

I kept Slackware 9.1 on a seperate partition before upgrading to 10, just in case, so I tried booting into 9.1 to see if the config was any different than slackware 10. I tried alsamixer and it wouldn't load, I also tried alsaconf and it wouldn't find a sound card.

That's weird, now it's not working under both operating systems. The only thing I can think of that's causing this is I moved my /boot directory to a new partition before installing 10, and added the kernel image for 9.1 and 10 to it. As this is the only thing that both operating systems are sharing, it's the only thing I can think of. Is there anything in any alsa configuration that depends on something in the boot directory, and maybe it can't find it as I moved it to it's own partition? Or is there any alsa configuration in the /boot directory itself?

I've had my share of problems with alsa not detecting the soundcard even though I knew it was supported. The solution was to recompile alsa, but you may have to find the howto for your soundcard at alsa's site so you know which modules to use and what options to use when compiling.

Try to recompile alsa. btw, if your soundcard is an i810 (I read your lspci) then this is your howto:

http://www.alsa-project.org/alsa-doc...odule=intel8x0

Hope it works out for you.

Thanks alot for the link. I'm halfway through it and it doesn't tell me to install the alsa-oss file. I don't think I need alsa-oss with just a stock Slackware 10.0, do I?
