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

However of course they should be able to play and capture even when
not using a mixer in advance ...
