A sound through hdmi-in, Dell Inspiron 24-3459 and Ubuntu 16.04

How can I receive a sound when switching the display to hdmi-in? My model is Dell Inspiron 24-3459. Using Screen 0ff/on button i can receive video from device connected to hdmi-in port but there is no sound from this device. My operating system is Ubuntu 16.04 64-bit.

I think I have to install a driver but I cannot find it.
