For clarity, "alsaplay -D 'plughw:1,0' music.wav" worked fine without any manual configuration. In your case, I guess you could be aiming for always converting to 32 bits, which would be OK I guess. In fact it might be worth experimenting to see how the automatic rate adjustment works (or doesn't).
