@vanvugt Thank you for your answer.
I tried the kernel versions 5.0.0-13 and 4.3.0-04 as well. For the first one, the same problem occured (sound only after a fresh boot) and the second one couldn't be installed correctly because of missing libraries (a boot was possible, but e.g. the mouse pointer was not moving).
I have already tried to reconfigure pulseaudio, to force alsa-audio to reload (it does reload but doesn't change anything).
Here is my output of aplay:
