Cannot start Fx Sound, the problem is in driver.

Good evening,  
[This](https://forum.fxsound.com/t/counter-strike-2-choppy-audio/2376/2) is a quick link to the most recent and complete version of my “first-aid-kit” list of settings to check.  
For your case specifically, performing a [manual driver uninstall](https://forum.fxsound.com/t/echo-due-to-fx-and-the-original-playback-device-playing-at-the-same-time/2112/2) and installing the latest version, [v1.1.20.0](https://fxsound.com/), afterwards, seem like the two tips worth trying first.  
So please try those, and post back with your results; and if your driver still remains unverified after that, I’ll ask @bvijay for assistance.  
I will be online for at least three more hours.

If installing the latest version does not help, check for OS updates. Support for SHA1 (file signature format, including drivers) has been discontinued and certificates are no longer issued.  
FxSound uses the current SHA-256 format, so Windows 7 requires updates to SHA-2 (sha-256).

Here is some supporting information:

> **Information from another major developer**
