2 * Minor numbers for the sound driver.
4 * Unfortunately Creative called the codec chip of SB as a DSP. For this
5 * reason the /dev/dsp is reserved for digitized audio use. There is a
6 * device for true DSP processors but it will be called something else.
7 * In v3.0 it's /dev/sndproc but this could be a temporary solution.
