Roccat ISKU FX Audio Mod Help

[ConnectionFX]

OK so I have a Roccat ISKU FX Keyboard and I want to change the default audio voice as it sound creepy.

I located the directory where all the wave files are stored
C:\Program Files (x86)\ROCCAT\Isku FX Keyboard\Wave\Volume

and started replacing them with my own wav sounds.

However when I go to use the keyboard profile switch which would initiate a sound response.. all I get is silence.

I made sure the wav files are the correct name and format but it refuses to play any audio that has been replaced.

Any advice? Thanks

yeah I have put the old sound files back and it works.. just does not with my sound files. I have made sure I recorded then to the same format. quality and tried to match the file sizes as close as possible to the original .wav file

confused....
