    this happened once to me i just went into the IDT Cont. Panel thru control panel and clicked on enable this device then right clicked the volume icon chose playback devices and made the hdmi my default before i closed IDT (if you close first it (IDT CP) unchecks it but i just ended up reinstalling my drivers at a later time and that solved it becuase it was annoying

    I find it's quite troublesome, basically flip back to "projector off" using the presentation key at the top right of your keyboard and then switch back to "projector only" and the sound then works for me :)

    So can we put sound through HDMI when we have video too? I was trying to do it yesterday and couldn't work out how to. HDMI seems to be rather badly documented with little information about how to use it.

    I also looked up about display port, it says that it can carry sound too, is there any way for us to do it on this laptop?

    It's definitely possible. I played a Blu-ray movie from my laptop to my HDTV through HDMI and it worked great, sound and all. However, due to copy-protection :)mad :), they only let you view it on one screen. Not that I mind, but I wanted to compare by plasma to RGBLED, lol.

    What does copy protection have to do with having two screens? :s

    I'm guessing this is one of the pointless and horribly irritating features that microsoft decided to include in vista... Is there some sort of crack for it?

    lol, it's not Vista. :)

    It's HDCP, if you've heard of it? High-definition copy protection? That is from all the home theater businesses. In reality, HDMI was made so they could have a stronger hold on copy-protection: the simplicity of one cable for sound/video came later.

    If you have two screens displaying HDCP content from one source, you are somehow illegally using the content. :confused:

    I'm confused here, I don't want to hijack this thread but how exactly does HDMI give a stronger hold on copyright?

    Sorry...well before HDMI, there was a myriad of connection options: composite, component, DVI, VGA, S-Video and then sound-wise you had optical, coaxial, analog, etc.

    HDMI is the "super" connector because it allows high-definition video and sound, so naturally everyone will want to use it. But, HDMI has built-in HDCP (you'll never find HDMI without HDCP: they go hand-in-hand). So now that everyone is using HDMI, because of its awesomeness, everyone is also now using copy-protection.

    Before, there was no "protection" from the source to the display: if you got video on your source playable, then it was de facto going to appear on the display. But now, there is one more item that has to be addressed before that happens: HDCP. Maybe stronger wasn't the right adjective: it isn't exactly stronger per se in more resilient to cracks, but stronger in that it will have a high invasion into homes.

    Sorry for the off-topic discussion.
