Channel Mapping Source property problem

Hi, I'm trying to use the functions dsp.AudioRecorder and dsp.Audioplayer for performing multichannel playback and record. I'm having an issue when I try to manually do the mapping of the channels for these functions

I'm declaring:

har = dsp.AudioRecorder;

and then setting:

set(har,'ChannelMappingSource','Property')

but i keep getting the following error

No public field ChannelMappingSource exists for class dsp.AudioRecorder.

Error in C:\Program Files\MATLAB\R2013a\toolbox\matlab\system\+matlab\+system\setProp.p>setProp
(line 14)

Error in C:\Program
Files\MATLAB\R2013a\toolbox\matlab\system\+matlab\+system\SystemProp.p>SystemProp.set (line 437)

Can anyone please help me figure out what I'm doing wrong?

This property is only available from version 2013b, not my current version 2013a... Hopefully it'll be available in the next release!
