No chance, I do not get any stable audio performance, I assume the Kubuntu
sound system is defective somehow. It is not about sampling rates, the pitch
is correct, just choppy. When calling the dial tone script repeatedly,
sometimes it works, sometimes it causes garbled sounds, then again it works,
with one attempt after another without doing anything else. 

Update: Right now I was so brave to uninstall some pulse library stuff, and
what should I say, the stuttering is gone, DMR is not decoding 100% fine,
but I assume now it is a matter of fine tuning the receiver chain and
decoder, audio itself looks OK. Thank you very much for putting me into the
right direction! How can find such a load of BS its way into an official and
widely used Linux distribution?!
