Hello,
I have two signals. One of them is meant for the left speaker, the other for the right. I am using a mac and my question is how can I output stereo audio.
I've read this: http://www.mathworks.com/help/toolbox/dsp/ref/toaudiodevice.html but it describes multi channel for windows only briefly.
Any ideas?
Thanks for your help.
Nathan.

I'm not at all sure, but I think you need to do something like MUX the two signals together into one signal and feed that into the ToAudioDevice block. Or maybe Concatenate instead of MUX. Either way use the first two channels of the device as your outputs.

Use the MATRIX Concatonate block to create an [Nx2] signal to feed the To Audio Device block.
In the case of feeding 2 scaler channels, this would then be a [1x2] signal. Use the "Default Mapping" selection.
If you are using Frame based signals the Matrix Concatonate works on those as well.
This is not obvious IMO.
