Missing files in generated code for USB Audio

Question for STM.
Could you please advise what to do to make the environment generate audio files?

Could anyone of you show me how to generate these files?
They are generated for all classes except audio.
I guess there should be these too.
Alternatively, please show me how to create an AUDIO Device using the STM32H5 processor.

Please for the msc class even adds

 

 
storage_configuration_number = USBD_Get_Configuration_Number(CLASS_TYPE_MSC, 0);
storage_interface_number = USBD_Get_Interface_Number(CLASS_TYPE_MSC, 0);
if( ux_device_stack_class_register( _ux_system_slave_class_storage_name,
 ux_device_class_storage_entry,
 storage_configuration_number,
 storage_interface_number,
 &storage_parameter) != UX_SUCCESS)
{
 return UX_ERROR;
}

Edited to apply source code formatting - please see How to insert source code for future reference.

Hello @konsul41 ,

Thank you for your bringing this issue to our attention.

I reported the audio files issue internally.

Could you please give more detail about the MSC issue?

-->Please for the msc class even adds

I found this code in app_usbx_device.c file

 

 /* Get storage configuration number */
 storage_configuration_number = USBD_Get_Configuration_Number(CLASS_TYPE_MSC, 0);

 /* Find storage interface number */
 storage_interface_number = USBD_Get_Interface_Number(CLASS_TYPE_MSC, 0);

 /* Initialize the device storage class */
 if (ux_device_stack_class_register(_ux_system_slave_class_storage_name,
 ux_device_class_storage_entry,
 storage_configuration_number,
 storage_interface_number,
 &storage_parameter) != UX_SUCCESS)
 {
 /* USER CODE BEGIN USBX_DEVICE_STORAGE_REGISTER_ERROR */
 return UX_ERROR;
 /* USER CODE END USBX_DEVICE_STORAGE_REGISTER_ERROR */
 }

 

Is this code missing from another file?
