My Fedora 29 system was working fine, but somewhere along the line I started getting distorted, crackling audio. Like, not just clicks or pops, but really bad. It seems like unplugging the speakers and re-plugging sometimes resets it, but not always, and only briefly. Plus, when I use the Test button in the sound control panel in GNOME, there’s a weird delay.
The hardware is
Family 17h (Models 00h-0fh) HD Audio Controller (I think built-in to my AMD motherboard). I also tried the HDMI out and plugged headphones into my Dell monitor — so that’s using
Vega 10 HDMI Audio [Radeon Vega 56/64]. Entirely different device and this rules out it being a problem with my 20 year old (yes, really) Cambridge Soundworks surround speakers.
I thought updating to the F30 beta might help, but it does not.
