PropertyChanged signal of org.BlueZ.MediaTransport is processed in pa_bluetooth_transport_parse_property() which updates t->nrec. This is called by : - First by filter_cb() of bluetooth-util.c - Then by filter_cb() of module-bluetooth-device.c which retrieve value of t->nrec before calling parse function, then it checks if t->nrec has changed before updating bluetooth.nrec property. As t->nrec has alreday been changed during first process, property update is never performed. This patch creates a new hook in pa_bluetooth_transport called PA_BLUETOOTH_TRANSPORT_HOOK_NREC_CHANGED. The hook is fired by bluetooth-util.c when the transport's NREC property changes. module-bluetooth-device.c won't listen the PropertyChanged signal of MediaTransport anymore. Instead, it will use the hook in pa_bluetooth_transport to get a notification when the NREC property changes, and update the sink or source proplist accordingly. const qualifier for returned pointer of pa_bluetooth_discovery_get_transport() is removed.
