I agree. I don't see this as an upstream issue because I have tried it on other distros - they worked as expected. USB hotplugging updates the audio device. However, a reboot simply restores whatever was last in use. For some reason, only on Ubuntu, it treats a reboot as plugging a new USB device. And this occurs on every flavor I tested - Ubuntu, Mate, Kubuntu and Xubuntu. In Kubuntu it can be slightly mitigated because you can set the default from the tray.
