When you plug an HDMI cable into a PC, it automatically switches video and audio to the HDMI device. This monitor does not have speakers. You'll need to plug speakers/headphones into the audio out (headphone port) on the monitor or switch the audio out back to whatever you were using before you plugged this one in. Changing the volume as answered before, you'll see that it says "Adjusts the volume of the external speaker"
