problem with STM32H563zi USBX audio class

[ABasi.2]

Hi

i’m triyng to use USBX audio class on nucleo-h563zi.

 

i have succed to make PC to recognise the board like a controller audio but windows have problem to start the device (error code 10), problem 0xA status:  0xC0440027

i’m stuck at this fase unfortunately

 

also i think there are some missing files in the middleware directory, in the example provided by ST UX_Device_Audio2.0_Playback 

(not sure is related to the error to start device)

there is this code: 

VOID USBD_AUDIO_PlaybackStreamChange(UX_DEVICE_CLASS_AUDIO_STREAM *audio_play_stream,
                                     ULONG alternate_setting)
{
  /* USER CODE BEGIN USBD_AUDIO_PlaybackStreamChange */

  /* Do nothing if alternate setting is 0 (stream closed).  */
  if (alternate_setting == 0)
  {
    return;
  }

  BufferCtl.state = PLAY_BUFFER_OFFSET_UNKNOWN;

  /* Start reception (stream opened).  */
  ux_device_class_audio_reception_start(audio_play_stream);

  /* USER CODE END USBD_AUDIO_PlaybackStreamChange */

  return;
}

the function ux_device_class_audio_reception_start(audio_play_stream);

is located in ux_device_class_audio_reception_start.c

that i’m not able to find in the files generated by cube MX for my project

 

any idea?

 

best reguards!
