PiZero 2 and Pirate radio

I recently upgraded my Pimoroni pirate radio with a pi zero 2. Re flashed a sd card with Buster legacy lite, installed the vlc radio with the bash script and everything said the files were installed but when I rebooted there is no audio and the Phat Beat VU meter isn’t working? Do I have to install additional driver files for the pi Zero 2 and if so which ones?
