USB Audio device on Nucleo F446-RE with CubeMX

Tried to get this working, no success.

HID is OK, virtual COM, MSD, everything works fine.

 

Audio class is recognized as composite device only. 

I've connected USB DP, DM and GND only. VBUS sensing is OFF.  12 MHz external HSE clock implemented, PLL for usb is generating 48 MHz correctly.

 

I'm on the latest cubeF4 version (1.15.0) and IAR IDE. 

 

Any ideas, why it's not working?
