Your decoder selects between analog and digital inputs automatically?

Please post your 'modules.conf'. You must use the second device of the 
card to get bit-identical output, otherwise volume/mixer settings are 
applied. You can use the second device either through 'mplayer -ao 
alsa9:hw:0,2' or through OSS emulation directed to '2' (options 
snd-pcm-oss snd_dsp_map=2)
