Hi Nick, I followed yours links and created new sound card and driver imx-itel. Now the new sound card is installed and listed by ALSA but without any kind of volume control, any suggestions? Anyway, now I'm going to check if outputs send I2S data. Riccardo - Messaggio Originale -

Hi, the chip has his internal "codec" you can see from the datasheet that has an i2s for the audio and an i2c interface for configuration. the codec that you select *ak4648* needs an initialization phase that is done usually via i2c. If the driver can't find the codec it will simply disable itself
