Description of problem: When I connect a usb sound output device (a DAC I suppose), I have tried two different brands, a running instance of pulseaudio stops working (most likely dies) If I try to start it again, running pulseaudio on the command line as a regular user, it segfaults. If I disconnect the usb sound devices, pulseaudio starts just fine. Version-Release number of selected component (if applicable): pulseaudio-13.99.1-4.fc32.x86_64 How reproducible: Always Steps to Reproduce: 1. Connect a usb audio device 2. Observe no functional sound output 3. Actual results: Expected results: Additional info:
