I believe there is a way that this can work.
What you'll want to do is send your audio through the HDMI cable to the HDMI-1 input. Then you'll want to set your computer up so that the audio goes through the headphone jack of the computer. Test this first to make sure that your audio IS going through the input.
Then, connect your computer via HDMI-1 to your computer.
Connect the audio cable (3.5mm male to 3.5mm male) from your computer's headphone jack to the Audio In port to the left of the HDMI-1 slot.
Then, you'll want to Edit the name of your input from "----" to either "PC", "DVI PC" or "DVI Devices", and instructions on that are found on the bottom of Page 10 of the owners manual.
So technically, what you'll be doing is porting your video in as normal, and the TV will accept that input, provided it's a support resolution. The audio will be ported through the analog port from the headphone jack of your computer to the Audio IN associated with the HDMI-1 port. By changing the name of the input, you're telling the TV to enable that audio port so it can receive audio. (By default, it would look for the audio in the HDMI signal). So by changing the name of your HDMI-1 input (To HDMI-1 "PC or "HDMI-1 DVI PC", etc), you're telling the television to enable that audio port.
Does that help?
I've recently purchased a Samsung ln32c450e1d LCD. I would like to connect the TV to my macbook (2009 model). I am using a hdmi connection However, this macbook, being an older model, does not transfer sound over the hdmi cable. I also have an audio cable that plugs into my mac's headphone jack and splits into red and white ends that go into the TV. The problem is that while I can mirror display using the TV, I still can't get any sound.
The connections are as follows:
macbook -> minidisplayport -> hdmi cable -> hdmi in slot 1 (dvi)->tv
macbook -> audio jack -> audio cable -> AV in slot 1 -> tv
I know that my video and audio inputs are in different slots, is there a way to select audio input source and video input source separately on the TV?
Thanks in advance
