I have seen this occur with repeatability under MacOS. Both Catalina and Big Sur versions. I set the Sonos device as my default sound output device. As shown below, ManCave and SonosBeam are Sonos devices. Within a couple minutes the wired ethernet stops working on my Mac and then eventually a kernel panic. I am able to control spotify music on the Sonos using the MacOS Sonos S2 App with no problem. All Sonos devices are wired with ethernet. I see this behavior when selecting both One and Beam products. Below is crash report from MacOS. Thanks
Dave
