The following commands can be used:

Question: How do I load the sound driver for the stereo audio DAC?
You need the nanosound OSS kernel module. This is included in the newer distributions (from may 2007).

Load the module by typing the command:

..# mknod /dev/dsp c 14 3
..# mknod /dev/mixer c 14 0
