OK, next question. In src/modules/module-protocol-stub.c I see the following comment 449 #else /* USE_TCP_SOCKETS */ 450 if (u->socket_server_unix) 451 if (pa_socket_server_get_address(u->socket_server_unix, t, sizeof(t))) 452 pa_http_protocol_remove_server_string(u->http_protocol, t); But I always thought that TCP sockets and Unix sockets where different. That unix sockets where the ones that exist as an inode in the filesystem, where-as TCP sockets are bound to a network port. Is the comment wrong or am I misunderstanding?
