Sound in gentoo...

[jpalfree]

after installing kde i realized that the sound didn't work and it was probably because i forgot certain sound support when compiling the kernel.... so i recompiled it adding what i thought i forgot.

the sound still doesn't work, unfortunately. when i open up kmix.. there aren't any output bars to fiddle with and kde control center keeps saying "unable to start sound server or retrieve possible I/O methods"

could someone help? i'm not sure what to do.

here's my "lsmod":

Run this:

su -
emerge alsa-utils
alsaconf
rc-update add alsasound default

Also make sure that your user is in the audio group. If not, add him in /etc/group.
