Volume control is unable to run correctly. Unable to open audio device '/dev/mixer'.
Please check that you have permissions to open '/dev/mixer'
and that you have sound support in your kernel.

Press Quit to exit Volume control.

I can't get any sound? What does this message mean? I just installed v9.0 Slackware.
I use an Intel d845glly Motherboard with integrated Intel Extreme Audio. Can't get any sound out of the system.

Please Help.
Thanks in advance.

as root:

chmod 666 /dev/dsp /dev/mixer

This might work. I'm not so sure though, I think that Slack 9 actually has those set correctly from the get go...

Also, as root, you might try running

lsmod

to see if the correct kernel module is being loaded. You might also check /etc/rc.d/rc.modules to see if you can find the module for your sound device there. If so, try uncommenting it. Also, if none of that works, try changing the permissions on /etc/rc.d/rc.hotplug like

chmod a-x /etc/rc.d/rc.hotplug

as root.

Other than that, beats me.
