Sound Problem! Alsamixer!

I ran the alsaconf and blacklisted the "snd-intel8x0m" and still have problems with sound.

When i type:
alsamixer

i get an error:
no mixer elems found

However when i type:
alsamixer -c 1

I get the alsamixer in console, it looks fine, nothing muted, but i still get no sound.
Any help would be appreciated.

What distro are you running, what is the output frim /sbin/lspci -v and /sbin/lsmod?
good luck.

The output for /sbin/lsmod is

Try adding this module to your /etc/hotplg/blacklist.

snd-intel8x0m

Take note of the m at the end.
good luck.

i did what you said, and it worked, but next time i booted the machine, it gave me an error message which i ignored (saying something about sound) and i clicked don't show again. and now the sound doesn't work. alsamixer returns the mixer and everything looks good, but no sound. Any ideas? How can I view that error message again?

My apologies mate, I misspelled the directory. I have edited that post. Have a look at dmesg, and post any relevant info. Make sure the module isn't loading, have a look at lsmod, and the blacklist file.
good luck.

this is what dmesg has to say about this:

Code:

ALSA ../../alsa-kernel/pci/ac97/ac97_codec.c:1860: AC'97 0 does not respond - RESET

hw_random: cannot enable RNG, aborting

PCI: Found IRQ 11 for device 00:1f.5

PCI: Sharing IRQ 11 with 00:1f.3

PCI: Sharing IRQ 11 with 00:1f.6

PCI: Sharing IRQ 11 with 02:00.1

PCI: Setting latency timer of device 00:1f.5 to 64

and it repeats the message a few times

What does lsmod and your blacklist file look like?
good luck.

take a look at your modules and stuff like that in your menuconfig (xconfig in the grafical interface)
have you ever recompiled the kernel? maybe you've changed some important option..

once,, I had to recompile my kernel and I inconsciently made some little bad changes.. It affected exactly my ALSA drivers.. and I was simply configuring the video modules

never recompiled the kernel
the lsmod looks:

Anything look funky here?

Blacklist looks ok, but lsmod says the modules aren't loaded. Try modprobing them.

Code:

modprobe snd-intel8x0

good luck.

what's interesting everything seems to work in gnome. I think i'm going to abandon kde and stick with gnome, at least till the new version of kde comes out.
Thanks for your help

If everything is working with gnome, it may be an arts problem.
good luck.

Well actually it's weird sometimes the sound works and sometimes it doesn't. As if sometimes the modules don't load right. One time the mixer will work, but i get not sound. Next time there is sound, and sometimes the mixer won't even work. Is this an issue with Slackware or hardware?

What does /etc/modules.conf look like?
good luck.
