MATLAB: Device ID problems

deviceidmultichannelsound

Hey guys,
So I am doing this experiment where I need to send out audio to 8 different speakers. 1 speaker is constant in all of the trials. In each trial, 2 sounds are sent out simultaneously. The other sound is randomly sent to one of the other 7. I have this script here which was sent to me by a colleague which can play multichannel sounds.
The syntax for the multichannel sound player is this –
pawavplaya(buffer', deviceid, Fs, 0, 0, 0, -1);
In her program, my colleague only uses one device, i.e. deviceid = 0. the 'buffer' which is the sound has a Nx2 matrix which contains the sound. If one column is 0, only one lead plays out the sound in one speaker and so on.
would anyone here know how to get deviceids for all 8 speakers? I tried the default matlab command but it doesn't work on a mac!!
