TDU 1 Radio not playing music

I've just got a fresh install of TDU 1 on PC from r/abandonware. After endless troubleshooting, I can't get the in-game radio to play music. I can change stations and modify the volume, but nothing worked. I even checked the sounds setting (everything maxed, orange lights all turned on). Nothing worked.

I checked the .station files. Everything is in order. What am I missing?
