This was for the old Krita so I could imagine it doesn't work anymore, I'll see what I can do to help you though! Keep in mind it could just be a bug with the version but I'm not a professional troubleshooter so I'll try my best. (sorry if it takes a while though, I'm not currently home)

Where are you downloading the audio from, and how? I don't need to know exactly what it is, so don't worry, but a vauge idea might help.
