''+The ES8316 codec is accessible via the ALSA hardware name ''hw:CARD=rockchipes8316c''. Use this name in audio commands, for example: ''aplay -D **hw:CARD=rockchipes8316c** ...''.
  
 +You can verify the hardware name with the following commands:
 ```shell print ES8316 hw name  ```shell print ES8316 hw name 
-~# aplay -L | grep rockchipes8316c -m1+$ aplay -L | grep rockchipes8316c -m1
