I, too, had the same issue with distorted sound when using headphones. After a lengthy convoy with support in which they were not able to resolve my problem, I figured out a solution which worked for me. Maybe it could help you, too.
First, I disabled any sound enhancements from within the Control Panel. This was the Bass Boost, etc.
Settings - Control panel - Hardware & Sound - Sound- Headphones- Properties- Enhancements - Disable Enhancements -Apply
Then, I balanced my sound
Settings - Control panel - Hardware & Sound - Sound - Headphones - Properties - Levels - Balance (I set mine at a 93/29 ratio)
Fixed the problem!! 😉😉. Good Luck!
