Start with the shutdown path shown in ovos_dinkum_listener/service.py, especially stop() and _shutdown(), then inspect ovos_microphone_plugin_alsa/init.py at stop() and the thread join. Reproduce the shutdown interruption and determine what must change so the service exits without hanging in microphone shutdown.
