Warning: New tone detection criterion must be added during the initialization before
xDspSysInit().
8.4 Getting DSP Resource Configuration and Routing Information
Description
The user’s applications can call this function any time after xDspSysInit () to obtain the DSP
resource configuration and the stream IDs assigned to the T-Ports of each type of the resources. The

case, use loose to get higher detection probability
