I get the following lines every time i try to play a song on the boombox and it redownloads FFMPEG. i cannot start any song.
the boombox just says "Loading" (i tried to play from youtube)

if i use a local ogg file it seems to start playing it but there is no sound
after i deleted the iammusicplayer the local file method does not cause visible FFMPEG error just no sound while the song plays

FFMPEG Error
Get Info Error
Reload FFMPEG

i am using this version: IamMusicPlayer-1.16.4-2.6
Forge 36.1.4 minecraft 1.16.5

I tried this version from the closed issue and also the linux64 version listed below.
The linux version just reloads the downloaded ffmpeg file.
I'm not sure if i'm missing something and sorry if i am.

kernel version: 5.11.11-arch1-1

New Release
Not used FFMPEG.
