and my workstation R2700X + RX580 + 16GB ram.
I have the same setup on both PC's with Fedora 29 XFCE. The R2200G setup no issues. But with teh R2700X machine the sound is good, but after some time I hear a click (when Iḿ doing something else) and then al sound is distorted/scrumbled.
I can't figure it out myself. If I logout and login again, sound is working o.k. for some time.
