So i bought hit sounds, uploaded custom sound files and enabled them... sadly all but 1 play annoying white noise. They are all less than 5 seconds and are in .wav format. When i test them in my inventory they play fine but when they're activated in game it's simply white noise. Can anyone help?

Try saving them with different encoding, when I was using audacity I had the same problem at least once, so I just messed around with the settings during saving and in the end it worked out.
