How could I use "startbackground(s)' continuous read AI 0 signal and output AO 0 voltage at the same time? (with DAQ 6212)

I learn startbackground(s) can separated get input channel and output voltage to output channel.

But I would like to make them together!

(Because if I use startForeground(), it looks like it need time to active DAQ so I prefer to use startbackground();)

(I test by USB BNC 6212)

I can separate them read AI0 port like:

s = daq.createSession('ni');
dev3_ai0 = addAnalogInputChannel(s,'dev3','ai0','Voltage')
lh=addlistener(s,'DataAvailable', @DAQsaveData);

%I save a function like:

function DAQsaveData(src,event)
  a=event.Data;
  save('D:\test\test.mat','a');
  plot(event.TimeStamps, event.Data)
end

startBackground(s);

and I can see the figure ploting, also save the data to txt file.

and I can output AO0 port sine wave like:

s = daq.createSession('ni');
dev3_ao0 = addAnalogOutputChannel(s,'dev3','ao0','Voltage')
s.IsContinuous = true;

s.Rate=200000;
x=1:1:100000;
y=transpose(sin(x));

lh=addlistener(s,'DataRequired', @(src,event)DAQsaveData(y));
queueOutputData(s,y) 
startBackground(s);

Then I can see sine wave on Oscilloscope.

But is that any method to make input and output at the same time at background?

I have try 'DataAvailable' and not sure it can use for output function.

like: (with the same function DAQsaveData I used)

s = daq.createSession('ni')
dev3_ai0 = addAnalogInputChannel(s,'dev3','ai0','Voltage')
dev3_ao0 = addAnalogOutputChannel(s,'dev3','ao0','Voltage')
s.Rate=200000;
s.IsContinuous = true;

x=1:1:100000;
y=transpose(sin(x));

lh=addlistener(s,'DataAvailable', @(src,event)DAQsaveData(y));

queueOutputData(s,transpose(y));
startBackground(s);

After this I can see sine wave appear on Oscilloscope for less than 5 secs, then input (with plot function) and output voltage are stop!

Because in 32bit I can use start(AI)+getdata(AI) and putsample(AO,1) in a very short time like 0.1 sec at sample rate=200000, and sample per trigger = 10000; (Actually I only need to output a single value to output port AO until next tandem data come form input port AI)

But if I use startForeground() it will take a long time more than 0.2 sec to run the daq. But startbackground() is much faster.

Is that any way to make startbackground() continuous let DAQ 6212 input and output?

THANKS A LOT!!
