I had the same problem and tried just about everything to fix it. Nothing worked. Then on a whim, I right clicked on the sound button on the task bar (bottom right) and then Open Volume Mixer. My Chrome volume was turned way down! I only listen to sound on the internet, Netflix, YouTube etc. That solved the problem, easy as that!

This was exactly what I needed to read. So simple. Thanks!
I was wondering why my music playback wasn't quite the quality I was used to even at 100% speaker volume.
Did many google searches to fix the 'windows 10 audio too low' issue
& I checked, unchecked every option for the playback devices.. but all I had to do was open volume mixer.
Anyway, just leaving this reply so that others facing this issue can find this search result sooner than I did.
