Dell Optiplex 780 USFF - Sound Output to TV via DisplayPort

This question has suggested answer(s)

I have my Optiplex 780 USFF connected to a full HD TV via DisplayPort to HDMI adapter.

Everything's fine, except the sound.

I read through serveral communities, but couldn't find a solution up to now.
I would like to have sound output via the displayport to my tv, so that I don't have to use any external speakers or headphones.

I got to know not every chipset is able to handle this.

Is this possible for the 780 USFF?

How would I have to do it?

    The DisplayPort of the chipset in OptiPlex 780 USFF has the capability to provide a scalable digital display interface with optional audio and high-definition content protection (HDCP) capability.

    I researched about the issue you described and came across the following Dell DisplayPort to HDMI Adapter with Audio:


    Check the "Customer Ratings" tab for this adapter wherein many users have shared their views about it. All that you need is a DisplayPort (Male) to HDMI (Male) Adapter.

    Please check and confirm if you are using the same adapter.

    Thanks & Regards
