I had an annoying Buzzing Sounds when strumming my 1st, 3rd, 4th, and 5th strings on almost every fret.
I did some truss rod adjustment, higher the strings action, but nothing works.

Seems like none of the strings are hitting any fret.

Can someone give me an advice on how to fix this?

Where are the Buzzing Sounds coming from?
Out of your amp or from the guitar?

Fret Buzz can be hard to see, but it definitely sounds like it.
