A:
DVI doesn't pass the audio, so you would need to send the audio to either a receiver, amplifier, audio system or speaker system - other than the TV.
So DVI to HDMI is good for the video in the HDMI-2 port - and then you'll need to Edit the Input, and information on how to do that is on Page 8 of the Samsung TV manual.
For the audio, you need a separate system or speakers.
We recommend using HDMI to HDMI if that is an option (this will allow you to pass video and audio through the HDMI port). If not, you can still use it with the above configuration.
Thanks for your support of Samsung products.
