I have installed slack 9.1 and then used swaret to upgrade , now i have no sound it says
/dev/dsp can't be opened no such device

. I have been through the posts and have tried changing the permisions with chmod as mentioned earlier and no luck, I have reinstalled alsa and arts and still no luck . my sound worked fine before doing upgrade.

when i do lsmod

Any help be much appreciated thanks ahead of time

did you try running alsaconf again???

yes i have done alsaconf a couple times and it says no pnp or pci card and then asks to prob for legacy isa <which i know i dont have but i say yes anyway>
it doesnt find one and then goes back to prompt

What happens if you modprobe ALSA modules manually? Any error message might be of help in solving the problem.

A similar thing happened to me recently, I believe it was some sort of mismatch between the actual kernel version and the version the modules were compiled for...perhaps worth considering.

hmmm... what's the ouput of this (and what make and model card is it):

cat /proc/pci

sound card is a generic 6 channel sound card. uses cmedia drivers.

cat /proc/pci

lol one thing i like about posting problems is i learn more stuff. lol..
as i mentioned before sound worked great on fresh install of 9.1 it only stopped working when i did swaret --upgrade . -a

and please anyone who asks me to probe something please give me command < still learning the commands>

try doing this (as root) and see if it works:

modprobe cmipci

or maybe a:

modprobe cmpci

OMG modprobe cmpci gives me back sound.

ok what did you have me do and how do i make sure it doesnt go away please and thank you

well, you could add the command to your /etc/rc.d/rc.local file if you want...

echo "modprobe cmpci" >> /etc/rc.d/rc.local

(or you could use a text editor, such as vi)

this is also where you'd put any other commands you want automagically performed at startup...

it should work fine, but i think the "proper" location for putting module loads in slackware is /etc/rc.d/rc.modules though i'm not sure cuz i'm not on my slackware box right now and my memory sucks and i'm also a newbie... look at that file though cuz i think it explains itself in it's comments...

ok i will
Thanks again

by the way, i think that cmpci uses oss, and cmipci uses alsa...

try this module instead of cmpci (it's alsa):

modprobe snd-cmipci

thanks,
however i just uped my kernel to 2.6.0 . and that fixed it too
