D6000 working but no sound

[lapk]

Hi

I just got the D6000 usb-c docking station for a MacBook Air M1and it is working great

I did this:

-Plugged 2 monitors one in hdmi another in DP
-Installed the latest displaylink manager, the addon for login
-Added the permission for display link manager for screen recording in the security settings
-Reboot and voila, Im in dual screen

Clamshell mode working perfectly, I get a third screen when I open the laptop
DP can do 144Hz in 2K, hdmi can not
Usb ports and ethernet also work great

My only problem is audio, I can't make any sound out of the dock, I tried both front and back outputs but nothing
I can see the Dell USB audio in my audio settings but when I select it nothing


Do you guys made it work somehow (maybe with a firmware upgrade) ?

Thx
