For XAP - we worked out the following rule:
Every audio-port is connected unless it is disabled. The plugin may
disallow disabled ports, in which case the host must connect it to a
zero-fill (or silent if we do silent buffers :).
/* we aren't connecting this port */
if (plug->disable_port && plug->disable_port(port_idx) < 0) {
/* connect to the zero-filled buffer */
}
