You need to load the module snd-ca0106. As root, su, or sudo type modprobe snd-ca0106.
I suggest adding the following lines to /etc/modules.conf or /etc/modprobe.conf. You will have to be as root when editing the file.
Code:
# ALSA portion
alias char-major-116 snd
alias snd-card-0 snd-ca0106
#options snd-ca0106
# OSS/Free portion
alias char-major-14 soundcore
alias sound-slot-0 snd-card-0
# card #1
alias sound-service-0-0 snd-mixer-oss
alias sound-service-0-1 snd-seq-oss
alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-8 snd-seq-oss
alias sound-service-0-12 snd-pcm-oss
Do not run GUI when logged in as root or else your installation will not work well or be corrupted.
Use only alsamixer to adjust mixer controls. If you use kmixer or any GUI mixer, it may not work correctly.
ALSA is the official sound system in Linux.
