Have this issue in Ubuntu 20 and Kubuntu 20 (which is what i have today ), audio sounds as if its clipping all the time, looking at the volume meter I see it go from say 30% to 100% intermittently,listening to a song/youtube whatever just this constant clipping where the audio spikes for no reason for a split second. Any ideas, it makes audio unbearable with the constant jumping.

I have a3.5mm jack into my motherboard to a 2.1 speaker set up,
