The latest HDMI cable versions support ARC technology, which is possible to transmit both video and audio signals to another device.

If you have outdated connectors on one of the devices, you will simultaneously buy a special headset for video and sound. To find out the version, you need to view the documentation for both devices. The first support for ARC technology appeared only in version 1.2, 2005 release.If the versions are all right, then connect the sound will not work.
