Hi Charles, I have a custom board with a cs4265 codec and the audio plays fine. During boot, the following error messages are seen: asoc-simple-card sound: control 2:0:0:SPDIF Switch:0 is already present cs4265 1-004f: ASoC: failed to add widget SPDIF dapm kcontrol SPDIF Switch: -16 SPDIF is not used on this board. Would you have any recommendations for getting rid of such error messages? Thanks, Fabio Estevam
