    You need to connect a speaker system by plugging it into the headphone plug-in. Your DVI-adapter is video only. Good Luck. :cool:

    i know that the one cord is only video, that is why i have a 3.5mm cord plugged into the headphone jack on the computer and then into the audio in on the back of my lg hdtv

    In your TV's interface, look for an audio input option. It's probably set for a cable audio in. Sometimes you have to manuallly change it. Also make sure the audio in is in the same input selection range as the video in (V1, A1 and not V1 and A2).

    Hope that helps!

    That's definitely weird, that you have no volume adjustment from your MB? I always hook up my JBL speakers and my Peavy sound system directly to my BlackBook on a regular basis. Also, check your Output on your Sound on your MB, by going into your System Preferences and click on Sound. Ensure that you don't have the MUTE Box checked, if it is, just uncheck it. Hope this helps. :cool:

    While you are here and on the Output tab, make sure that Headphones - Built-in Output is highlighted, as I have occasionally seen no output or input selected (seemingly randomly).
