This is my route to get this script working(kinda): 1)Apply balonik's modification. It's two comments below. 2)If you find that you aren't able to download the full audio, you shall watch the video from the beginning again instead of playing it midway. 3)If you find that the download icons are not visible, turn off the script first, refesh, watch a few seconds, turn it on again and refresh. After these steps, I can download audios properly in most times. I'm not sure if this method will apply to every PC. But I hope this will be helpful to someone at least.
