/etc/modules.conf To configure the alsa drivers, you need to add some lines to /etc/modules.conf: cat >> /etc/modules.conf << "EOF" alias char-major-14 soundcore alias char-major-116 snd alias snd-card-0 snd-<soundcard-name> alias sound-slot-0 snd-card-0 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-midi EOF <soundcard-name> needs to be replaced with the driver relevant to your soundcard. If you have more than one soundcard, you can add additional sections by repeating the above but changing the first 0 to 1 and so on. After editing /etc/modules.conf you need to run depmod. If the drivers you have compiled are for the version of the kernel you are currently running, simply run depmod If you are compiling drivers for a different kernel version than those you are running, you will need to use a line along the lines of: depmod -a 2.4.19 -F /boot/System.map-2.4.19
