********** Method of Sound Manager (API) **********
*/

/**
 * Call "connect" function of Audio Manager.
 * Getting resource right to output audio stream.
 * Please input following keys with value into json string object in argument.
 * In case of using libsoundmanager, 
 * json_object *jobj = json_object_new_object();
 * json_object_object_add(jobj, "sourceID", json_object_new_int(100));
 * json_object_object_add(jobj, "sinkID", json_object_new_int(100));
 * call("connect", jobj);
 *
 * The order of arguments is not important.
 * 
 * #### Parameters
 * Request key
 * - sourceID   : Source ID getting in return value in registerSource or appname. 
 * - sinkID     : Sink ID. This should be more than 0. If no request, defalut value is set by sound manager
 *
 * This will be changed in near future because these arguments should be aliased like
 * sinkID:100 -> sinkID:"speaker"
 *
 * This will be modified after integrating 
 *
 * #### Rreturn
 * - error      : Error status number. If error is 0, it means the request is accepted, otherwise error message is attached with error code in reply message.
 *
 * #### Note
 * sourceID and sinkID should be more than 0

/**
 * Event "asyncSetSourceState"
 * This event is one of the result of Audio Management for connect/disconnect.
 *
 * #### Parameters
 * Request key
 * - sourceID     : sourceID to be commanded by Audio Manager. The contents of command is sourceState
 * - handle       : handle is the dynamic number managed by Audio Manager. Please return this parameter to input ackSetSourceState as is 
 * - sourceState  : "on" is the instruction that application can output sound
 *                  "off" is the instruction that application sound right will be removed_main_connection
 *                  "pause" is the instruction that application must stop output sound because other applications temporaly got sound right and will output sound
 *
 * #### Note
 * This function is very important for applications to realise the sequence of Audio Management.
 * An Application which matches with sourceID in the parameter of asyncSetSourceState has to return ack to use this function
