So you’re trying to add an audio component for presentations. Epson projectors do not have pass-through audio, meaning that there is no way to connect audio directly to the projector to play audio. However, it is possible to connect a stereo system directly to the same computer or component to which the projector is connected. Then, the audio will synchronize with the on-screen presentation without problems. If you need to find a stereo or sound system to ensure you have sound, you could start by looking at a site like hifisystemcomponents.com

Instruction
Connect Audio
1. Determine what type of audio output you will be working with. If you use a computer, it is likely that you need to connect it to the headphone port, which is a small, round port called a 3.5mm jack; it is necessary to move on to the next phase. If you use a DVD player, you will be using the standard RCA audio outputs. These are two round doors, one red, one white, and probably on the back. If this is the case, go to step 3.
2. Connect a 3.5mm adapter to an audio RCA to the headphone jack. This will allow the headphone jack to accommodate RCA audio outputs for connection to the stereo. Insert the thin, long metal end into your headphone jack.
3. Connect an end set of the RCA audio cable to the RCA audio outputs. Be sure to match the red and white color coding. Then, connect the other end series to the audio inputs of the stereo device; these will be identical in shape and color.
4. Set the stereo to receive an input signal from the computer. How this is done varies from stereo, but there are usually various input buttons or an input line. For more information on this, refer to the stereo manual for more details on the input mode.
Video Connect
5. Locate the video output on the device you are trying to connect to. On a computer, you will be looking for a VGA output, which is a trapezoidal shaped door with a set of pins inside, or a DVI output, which is a rectangular output with a dash in the middle. On a DVD player, you will be looking for an S-Video port, which is a round port with four pins inside.
6. Connect a video cable to the component video output port. For a VGA, push the cable connector into the tightly fitting computer port, and then secure it by turning the two external screws until they are secure as well. For DVI or S-Video connectors, simply insert the plugs which fit only one way.
7. Locate the appropriate video input on the Epson projector. This port will be identical to the one you just used on the component. Connect the other end of the cable to this port.
8. Turn on the projector. Most projectors will automatically determine which input is sending a signal and display that on the screen. If not, press the input or source button on the projector until the image is displayed.
