I want to replace the default Radio Station music with my own silent .wavs. I tried using the default method of dropping them into the specified folder listed in the wiki but it still plays the default radio music.

I found the files I want to replace but am unsure on how to proceed I assume I need to package them with Unity.

So in

H:\SteamLibrary\steamapps\common\UBOAT\UBOAT_Data\StreamingAssets\Packages\uboat\Bundles\

2 files

uboat.music.radio.germany (the sound file I assume?)
uboat.music.radio.germany.manifest

In .manifest

Assets:
- Assets/Packages/Music/uboat.music.radio.germany/Manifest.asset
- Assets/Packages/Music/uboat.music.radio.germany/Music/ANW1484_20_Germany.wav
Paths:
- 3880f769cc86afa41b81873a599b8998: Manifest
- fa930334903969147a71d90d7919c1ff: Music/ANW1484_20_Germany

which is one of the files I want to replace and they are also listed in

Bundles.manifest

Info_479:
Name: uboat.music.radio.germany
Hash: 56623b66058200c93793a03d3b57b07a
CRC: 3875412770
Dependencies: {}

and the tracks are listed in the Radio tab in Sandbox.xlsx

Nowhere in general.xlsx did I see any entries to change Radio music volume, everything else is in there, so it seems this is my only option is to mod in silent .wavs to replace the default radio stations.

So if someone has pity and a few minutes of time to tell me how to replace/mod this I would appreciate it.
