STM32F429I-DISCO USB Problems

Hello. I have serious problems getting the STM32F429I-DISCO board to work either in USB Host or Device mode. Now I'm trying to get audio example from USB library v2.1.0 to work but when I use internal DMA mode I get error:
usbd_audio_core.c(431): error:  #20: identifier "usbd_audio_Desc" is undefined

When I use dedicated endpoints in interrupts the board gets recognized after many connect/disconnect tries but it also doesn't work. It's starting to annoy me.
I know that STM32F429I-DISCO doesn't have audio codec. I wanted to output sound via PWM.
I tried to modify USB examples from Discovery firmware, also without success.
I would be grateful for help.
