I know that the audio requires a standard audio jack out of the headphones, and then into the audio in on the back of the TV using the red/white cables. Will this setup provide audio through the TV speakers, or will it not work because the TV will be set on HDMI and not the input the audio is connected to? I'm hoping that it will, but to test it out I need to buy the necessary cables. ![]() If you think this may not work is there another configuration that I could use? So basically will a headjack cable to the red/white audio in work eventhough the video will be going through an HDMI input. I'm basically setting this up so that I can use the TV for a display when watching movies through either renting on iTunes or just as a general display. So, first off, right click on your desktop and click on Nvidia Control Panel. Thanks in advance for any suggestions anyone might have. A window should pop up with a menu on the left that looks similar to the one below. On the right side of the menu, you’ll see a bunch of settings. Click on the second monitor (your TV) and make sure the settings look similar. I hooked up my MacBook to my Panasonic HDTV through my Onkyo surround sound receiver. The image is sent through an HDMI cable and the sound through a Digital Optical cable. The optical cable has an adapter that lets it hook up to the headphone jack in my MacBook. I couldn't hook up my TV to accept the sound directly from my MacBook due to the fact that the TV only had a digital "out" and not "in". Meaning that the TV can output the sound from the television but the television cannot receive a sound signal from another source. I changed the settings on the receiver to accept the image through the selected HDMI and to receive the sound through the selected Digital Optical connection. If you are trying to hookup your macBook directly to your HDTV, you will need to check some sort of advanced settings in order to designate that you want to receive audio from a different source than the HDMI but still allow the picture to show through the HDMI. I believe that not all HDTVs will allow you to output sound because most can only export sound and can't have sound imported through the digital optical cable. One last note, full 1080p resolution can only be achieved by using your MacBook in "clamshell" mode. ![]() #WHEN PUTTING HDMI FROM MAC TO TV HOW TO EXTEND SOUND 1080P#
