/dev/dsp8 means 8-bit unsigned format and /dev/dsp16 means 16-bit signed
little endian format.. These names doesn't have anything with card number.

pcm01 -> /dev/adsp (alternate DSP), PCM devices 2-3 aren't mapped to OSS
space... This is due to another scheme (ALSA have soundcard and PCM
devices; OSS have only devices).
