I've just installed Mandrake 9.0, and everything works perfectly except for the sound. It seemed to configure properly during setup, but:

If you try to play an mp3 or something, the player appears to work but no sound comes out.

Under mandrake control center it says that the sound card is detected and driver cs46xx is listed but: modprobe cs46xx fails and it says there's "no such device"

dmesg says "cs46xx: cs46xx_setup_eapd_slot() Failure to write the GPIO pins for slot 12", and later "cs46xx: Unable to detect valid cs46xx device".

Any ideas? This card worked fine under Windows 2k a week ago.

What kind of card is it? You probably have the wrong module. Type, as root, in a terminal:

lspci -v

This will give you details about the card. Since it is detected, it should provide the right info. Also, make sure in your /etc/modules.conf file you have:

alias sound-slot-0 <modulename>

If it is in fact cs46xx then make sure it looks like this:

alias sound-slot-0 cs46xx

Also, you'll want to make sure your /dev/dsp and /dev/mixer are useable by everyone:

ls -l /dev/dsp
ls -l /dev/mixer

This will list the permissions of both devices. If it looks like this:

crwxr--r--

then you'll need to chmod them so they look like

crwxr-xr-x

by typing as root chmod 755 /dev/dsp and chmod 755 /dev/mixer.

Hope this helps.
