@dengyangchao have you used the relevant mixer settings, seems to me that your configuration is incomplete on the codec side?
@bardliao can you try to reproduce?
bardliao commentedon Nov 5, 2019
@Liviali155 @plbossart I believe that is a mixer setting issue. @Liviali155 Could you try
rt5682.txt first?
