Argon Audio Fenris A4 aren't recognized

Hey y’all
I’m trying to connect the above mentioned Bluetooth speakers with my Hass Instance.

So I tried the actual raspberry pi OS and the os recognized the speakers broadcast and I conneced them, but hass doesn’t find the broadcast messages, when I’m using ssh and bluetoothctl

I updated all firmwares and the bootloader with pi os

I’m using Home Assistant OS
Core is 2026.9.1
Supervisor is 2026.09.0
Operating System is 18.2
On a pi 4

Any suggestions to fix the problem?
