I found out some rather interesting things playing around with the ALSAmixer, a friend just showed it to me: I can controll the loudspeakers on the top and the TRS-audio-jack through "Headphone", and the bottom ones through "PCM" (whatever that is). This kind of solves the problem, though this should (somehow) be done automatic.
