Okay for Windows 10/11 users who are having this issue and aren’t so tech savvy like me, I hope you come across this during your google search to save you time.
Basically this is just a .bat file I made that opens AudioRelay directly without using the main exe. Eliminating the need to modify anything. It forces javaw as the main engine instead of java.exe. You can change “C:\Program Files (x86)\AudioRelay” to wherever you have your installation folder saved.
Just copy and paste this in notepad and name it as whateveryouwant.bat and make sure to save as “all files’” and not text:
@echo off cd /d “C:\Program Files (x86)\AudioRelay” start “” “.\runtime\bin\javaw.exe” -cp “app/audiorelay.jar” com.azefsw.audioconnect.desktop.app.MainKt exit
