SGTL5000 headphone output

[aravinthkumarja]

Dear All,

I'm using sgtl5000 audio codec in imx6 platform. When I use real headphone, headphone out is working. But if i take only HP_L and HP_R to some external speaker, I'm not getting any sound. 

Is there any Headphone detect pin.? How to bypass the output.?

Regards,

Aravinth

Hi Aravinth

one can check external speaker impedance, for HP (headphone) Load 16Ohm (min).

Ultra-Low-Power Audio Codec | NXP
