WAV files not playing

So, I have 2 .wav files named mic_click_off and mic_click_on. They both play correctly via VLC, but if I insert them into my TeamSpeak 3 Client\sound\default folder, it does not play at all. I’ve gotten other files to play through replacing the files in the default folder, but for some reason these two files won’t work.
Below are download links to the two files in question.
And yes I have verified that the playback profile has the own client plays mic clicks option is ticked and the profile is chosen.
Any help would be appreciated.
