The audio driver provides the **hdf\_audio\_render**, **hdf\_audio\_capture** and **hdf\_audio\_control** services for the HDI layer. The driver service nodes in the **dev** directory of the development board are as follows:
Configure the driver node, loading sequence, and service name in the .hcs file. For details about the HCS syntax, see [Driver Configuration Management](https://gitee.com/openharmony/docs/blob/master/en/device-dev/driver/driver-hdf-manage.md) in the HDF framework.
