Niagara is not audio reactive?!

Following closely Niagara audio visualizer tutorials such as this one

The audio just didn’t activate the Niagara system. The strangest thing is that I got it to work after many tries - for a few seconds (like 20sec), I than save the system and after this - whole day of trying didn’t bring the result back. I restart the engine,computer, build the whole fx again - nothing.

It felt like the sound didn’t connect with the particle system…
**I am attaching the Niagara system **- to see If the problem is in the Niagara system somehow or in my drivers/windows - I have no idea what.
Please help me by testing this thing or if you can - send me working system to test it myself.

Please try to see if it works on your machine and tell me?!

The engine is 4.26.1 running on Win7.

Ok a solution!
I completely remove the drivers (Realtek High Definition Audio Codecs Drivers) and continue with the windows generic one. It works!
