Raspberry Pi audio YouTube vs. Vimeo

Hi!
First time posting so hope I get things right.

I’ve built a brand new raspberry pi 3 with the latest Kali image. Per guidance I found on the net ive installed alsa utils, mpg321, and lame. I also copied a stock Config.txt to /boot. The sound is working but not from all sources. The best example is when I go to YouTube and play videos the sound is perfect but when I go to Vimeo it just sounds like white noise/ static. If I boot raspbian both sites videos play / sound fine. I’m wondering is there an additional package that needs installing? Is it a compression or codec thing? Appreciate any advice!!!
