Split audio into left and right channel.

I have a sine sweep which has to be played first in left earphones only and then repeat the same sweep for the right ears. How can I do that. I have added an image of my code. I did the way it was given in http://forums.ni.com/t5/LabVIEW/How-can-I-separate-Left-and-right-audio-channels-in-labview-8-5/td-p... but it does not work. Please help me as I am new to it.
Hey again PG1985,
I've just had a quick play around with the sound functions and have built the basic VI below to demonstrate how to modulate sounds between different audio outputs for different left and right outputs. You'll see below in the VI Snippet that after initialising the sound output channels, all you need to do to vary the output sound is build together an array of two waveforms as your input to your sound task, this will differentiate between the Left and Right speakers for us. The waveform in array index [0] will go to the left speaker and the waveform in array index [1] will go to the right speaker. In the loop where I generate the sound, all I do is produce the waveforms and use the Build Array node to create an array of sounds, then use this as the input to my Sound Output Write. So, to eliminate sound to an individual speaker, all you need to do is set the amplitude of the input signal to 0.
In terms of your application, I suggest that whilst you are outputting the first sine sweep, output a Sine Waveform with an amplitude of 0 to the right headphone by building an array of the two and wiring it to the Sound Output Write, then doing the reverse for when you want to play the Sine Sweep in the right speaker.
Hope this is helpful, I had some good fun trying to get this to work!
hola a todos quiero graficar los canales R y L de audio de mi mydaq
