mpg123 broken under Raspbian STRETCH?

[cyperghost]

Hello, I've installed RetroPie 4.5.1 directly from download section.
I wanted to try out mpg123 and it installs fine.

1. If I use mpg123 /path/to/*.mp3 it plays fine in terminal and works like it should
2. If I use mpg123 /path/to/*.mp3 & then the player will not work

Meanwhile I use mpg321 works like it should but is much bigger in footprint. Can somebody explain or give me some help please?

Best wishes

EDIT:
BTW Fade in and fade out of BGM works best with this script. Do not know what the poster later did wrong with his da hood image ;)

@cyperghost 4.5.1 image is Stretch - or you mean you are trying to use on Buster?

Nothing Buster related in this anyway.

Try mpg123 -q whatever.mp3 </dev/null &

@BuZz sorry you are right it's stretch on standard image. Can you explain further? Why this happens. I'll test later - thanks

Thanks ... this worked!
So < /dev/null inits a EOF in file input, never saw this. Is this a common method?
mpg123 is the clear prefered mp3 player, very small footprint - no stucks in sound during loading. Perfect.
