I just bought a Dell ST2410 24" display, it has HDMI DVI and VGA inputs, but also has two connections, Audio in and Audio out, on top of it it has many small holes so the question is, are these holes a speaker??? or are they just used to take out heat??? I'm asking because when I connected the cable from my computer to the audio in input I didn't get any kind of sound out of it. Any help would be appreciated. Thanks in advance.
