This bug has been fixed in Release 14 Service Pack 2 (R14SP2). For previous releases, please read below for any possible workarounds:

This problem has been fixed in MATLAB 7.0.1 (R14SP1). If you are using a previous version, read the following:
This has been verified as a bug in MATLAB in the way that the BEEP command is executed on certain operating systems.
If you are not able to hear the system beep when you use the beep command, the following solution can be used to make a sound on your machine.
NOTE: This will not solve the problem of other functions that use BEEP, but it will allow you to have sound in your own applications.
The workaround involves creating another function (called, for example, beep2) which will play a sine wave.
function beep2
% Play a sine wave
res = 22050;
len = 0.5 * res;
hz = 220;
sound( sin( hz*(2*pi*(0:len)/res) ), res);

I just discovered that if you change the default system beep sound in OS preferences while Matlab is open, beeps in Matlab will produce no sound. You will need to relaunch Matlab to produce the beep which will be the newly selected sound.
