I just tried again under jack, with realtime scheduling.
Responsiveness is very good and cpu load stays reasonable.
No xruns reported. The distortion comes and goes unpredictably;
things sound fine for a minute or so... then the distortion
appears and keeps happening for a minute or so... then it "fixes
itself".

Very weird.
