### Description The `source_disconnect` method in the liquidsoap client was still using the old names of the 2 harbor input (currently named input_main and input_show). Remove the `source_disconnect` method, in favor of the `source_switch_status` method, to have a single source name mapping between playout and liquidsoap. This is a missing update from a refactor made a while ago: 2f9f60e639f13854094abb0f43730aebc9c89cee ### **Links** Potential fix for https://github.com/libretime/libretime/issues/2796
