This is because with music players you usually play 44kHz content, such 
as from CD. However the digital output of this (and most other consumer 
cards) does only support 48kHz sampling rate. The alsa-device ',2' is 
per convention bit-identical thus non-resampling.

Use /dev/adsp with mplayer
Use /dev/dsp with all other OSS applications (:= leave as is)

Direct /dev/adsp to ',2'
Direct /dev/dsp to ',0'

=> options snd-pcm-oss snd_dsp_map=0 snd_adsp_map=2
