Thanks

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

Hi Fresxc,

Can you tell me which BSP your are using.?

Also your output device is Speaker or Headphone.?

Regards,

Aravinth

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.

你好，请问问题最后解决了吗？我也遇到了相同的问题

Re: wm8960 playback sound small

arthur_rythm — Tue, 19 Feb 2019 15:30:04 GMT

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.

Re: wm8960 playback sound small

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.
