how iam planning to use them
both " dvd player from the sound system / projector " have usb ports
i am not planning to get near the projector usb at all
since the dvd player with the sound system have a usb port
with all of that being said ,

how i can connect my projector to the sound system ?
in a way that i will see the video from the projector
and hear the audio from the sound system ?

my idea was to buy hdmi to hdmi cable " since its transmit audio "
and put it between the sound system hdmi port and the projector hdmi port
and the usb will be inside of the dvd player " not the projector "

therefor i should have the video going from the dvd player usb to the projector
and in case the audio went along with the video i can mute my projector
and i can still hear everything from the sound system right ?

i want the projector as a display unite only
and the sound system to be the read and write stuff
would it work this way ?
thanks .

All you need to do is run the HDMI out from the dvd to the HDMI in of the projector.
Projector has nothing to do with sound only picture. All sound controlled by DVD surround sound unit.
You don't need to use the USB on the projector at all.

thank you so much
what got me confused that the projector have a built in speakers ,
so i thought when i connect the hdmi to the projector its going to automatically disable the sound from the sound system speakers , thanks for making things clear

Did they work for you Ray? I have a Sony BluRay Surround Sound system hooked up with HDMI cable. When I switch the Progector input to TV so I can watch regular TV, the sound does not go to the surround sound system it will only use the speakers on the projector (which these are horrible speakers).

How can I get that to work properly?
