No audio coming out of the surround sound when connecting HDMI cable from Laptop to Projector.

[tinothynguyen]

I have connected my HDMI cable from my laptop to a projector. From my projector I have connected the component video cable to the surround system but there is no audio coming out (I have selected the correct input as well). Video does project but no audio. I looked at playback devices and it says sound is coming out of my Panasonic TV even though the tv is not connected anywhere. What should I do?

The component video on the projector is an input and has nothing to do with audio anyway.
If your projector has audio out then you will need to connect that to your surround system.
If not then you can connect the laptop headphone audio out to your surround system and set that as your audio device (not the HDMI).
Last resort is to use an HDMI audio extractor

to get an audio output for the surround system. This option will give you a digital audio output which should sound better if your surround system has a digital audio input.
