Probably the problem is that you have matlab 64 bit. Try to use matlab 32 bit with DAQ toolbox.

This file looked interesting so I gave it a shot, unfortunately I get the following error when trying to run run_me.m:

Error using analoginput (line 46)
To learn about using data acquisition devices on the win64 platform, see the documentation on the session-based
interface.

Error in run_me (line 7)
ai = analoginput('winsound');
