Back to the original question: > However, where/how do I listen for the signal? I also tried setting a > dbus match rule: > dbus_bus_add_match(system_bus, "type='signal',interface='org.PulseAudio.Core1'", &err); You don't need to add a match rule (trying to do so won't do anything useful, because the match rules are managed by the bus daemon, and in a peer-to-peer connection there's no bus daemon involved at all). Do you register a message filter with dbus_connection_add_filter()? If not, then that's the problem. By the way, please don't top-post on mailing lists, and also plain text messages are preferred over HTML. -- Tanu
