    Which MacBook Pro do you have? If you have a mid-2010 MacBook Pro, it may be outputting sound via mini Displayport. Go to the Sound section of your system preferences and change it to line out.

    I think the issue is that you are trying to use the DVI/PC port to input audio, when you have an HDMI cable connected. If it is anything like my T220HD, there should be a separate input for HDMI audio, or you should try a mini-Display Port to HDMI cable that includes audio (either from the MDP port or USB) or utilize a DVI cable instead of HDMI. The audio input you are using will only work when the TV is set to DVI (or VGA if it has it), not HDMI.

    I know what u mean but my macbook pro is the old version which does not allow Adio to go through the Mini DisplayPort :-(

    Also I can not change anything from the Sound section of the system preferences.

    Have you looked at Audio Midi Setup in the Utilities folder, might be something there.

    Well from what I see, your converter may be the issue, since it is likely sending a false digital audio signal. If you were to try a MDP to DVI converter, then DVI to HDMI you wouldn't have the issue, but the MDP to HDMI converter that has some sort of signal traveling down the audio wires, or there is some sort of cross-talk causing a false signal.

    Also, have you updated the firmware on the TV, as there is a new firmware available, which was not likely loaded on the TV due to the hight likelihood it was packaged before the new firmware was released.

    First of all I really appreciate ur help and support.

    Today, I got the MDP to VGA adapter to see what the problem exactly is. The result was good. I got the video and and i got the Audio from using the Audio cable. So now we know that the problem is from the MDP to HDMI adapter which is sending as u said and mentioned a false digital audio signal. The million dollar question now could we fix this issue? if yes, how ?

    I did updated the firmware on the TV and no luck :-(

    please guys do not give up and be with me until we solve this issue together.

    Thank u

    On the TV's settings, do you have the option to choose the audio separate from the video source?
