Sure enough, when I opened speaker icon > Playback Devices > Speakers > Properties > Enhancements dialog, I found the “Disable all enhancements” option checked. This will help make your speakers somewhat louder. To make your speakers louder, right-click the speaker icon in the right bottom corner of your screen > playback devices > speakers > properties > enhancements > check loudness equalization.

I was therefore happy to see a post by ‘ferganer80’ on that solved my problem: Or when sharing a DVD with friends or family without external speakers. The problem is acutely felt when trying to listen to a Facebook or YouTube video even while sitting in a quiet room - I have to strain my ears to make out what is being said. Have all the latest audio drivers installed. Very low volume, but very loud sound, maxing out volume would blow out the speakers/headphones. Does anyone know the cause of this It's the same on my desktop. The sound is loud at 10 volume, when 50 volume should be medium and 10 quiet. I have been plagued for over a year with a problem on my Lenovo T420 laptop: the internal speaker volume is ridiculously low. Right now my PC sound is far too loud even when on low volume.

My laptop speakers are too quiet
