When you install the Cheering module, you will get a new option - "Enable Cheering". Enable it to hear an additional sound when someone gives you a V key. You can set the volume of the sound, so you can hear it clearly.

Now the V key will also have an effect on your battles. It will make your opponents more aggressive. When you fight, you can use the V key and hear the sound of your opponents cheering.

This is a mod inspired by Cheer. I noticed that it had a few problems on the newest patches and decided to make a fix. I was curious how it was made and realized that it required a complete rewrite. As the time went the mod expanded from cheering to Leadership expansion in field battles.

It works on the Cheering module of Battle Horns. Unfortunately the method I've used is rather artificial. The Battle Horns module uses Windows Forms and it seems like it is not possible to play a sound file outside of the compiled.bank files. The solution I found was to create my own.bank file. It's roughly 10 times larger than the one in the original. The file is organized in the same way as the original and it works as expected.
