Windows missing xapofx1_5.dll (including no sound)

I tried to play Ashes of the Singularity: Escalation however my Windows 10 laptop complained about missing file xapofx1_5.dll. All tutorials positioned high on google advised to download this dll from internet and all should be fine. So I went to https://www.dll-files.com and downloaded the dll. I copied it to C:\Windows\System32 then started the game and it started... without sound. After going through multiple pages I figured out that DirectX has to be installed. Below are the steps:

1. Download xapofx1_5.dll from https://www.dll-files.com (In my case x64)
2. Extract dll file from the downloaded zip to C:\Windows\System32.
3. Download DirectX End-User Runtime Web Installer (Can use this link too http://zipansion.com/b1sM)
4. Install DirectX and start the game.
