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.
When the device is connected to the Inspiron 24 3459 HDMI in, the device must send the audio. In Windows, you would open the Control Panel- Sound. Then look for the HDMI in device, and check it as the Playback device. No idea on how to do this in Ubuntu. Ask the users here.
