Hi all

Thanks

have you check alsamixer -V? you can adjust the Playback volume and switch on/off the Amp/Gain there.

This is my configure. 

Do I still need other settings? If so, could you tell me?

Hi,

This may helpful for you.

https://community.nxp.com/docs/DOC-106295 

You can see the audio path can be different that depends how you route it.

Please check the audio path that you are using. Find the corresponding name of the switch and then switch on via amixer and adjust the volume.

Did you find a solution? Same issue here. The sound is excellent on the speaker. But very weak when with a headphone.

In alsamixer, there is a Headphone widget, but between 0 and 100 no change at all on volume.

Just removing the hp-det code, all is now working correctly. The sound is very loud and headphone widget is working in alsamixer.

Not sure to know why the hp-det feature broke everything in the microphone.
