Can you try, if this works: 
$ alsaplayer -o alsa -d plughw:1,0 test.mp3
Note the "plughw"-part. This will make ALSA automatically convert the

sound data to a format, that the hardware can understand (like

converting stereo to 4-channel data etc.)

Not necessarily. Many soundcards, especially USB, don't have mixer

controls for everything. Some don't even have a mixer at all (like the

M-Audio Quattro.) And some use very complicated mixers like the RME

cards. 
However of course they should be able to play and capture even when

not using a mixer in advance ...
Ciao
