Now I want to play sounds 1 to 3 at the same time. My question is now: Can ALSA do automatic mixing for me here or do I have to do the mixing on my own? In other words, can I simply feed all these three sound streams to ALSA or do I have to mix them into a fourth audio stream first and feeding this new fourth stream to ALSA then?

The easiest thing for your application is to just open and play multiple audio streams and allow a system mixing daemon such as PulseAudio to take care of the mixing.
