Jack Detection Error in ADAU1761

Awad_Zafar

Hi!

I am using ADAU 1761 audio codec in one of my projects and require to detect jack detection while working with both Line output  and headphone output (hpout). Whenever I enable jack detection and plug in headphone jack it switches off (mutes) the headphone output instead of muting LINE OUT. What would be the possible reason as datasheet mentions that jack detection should mute line out.

    Maybe you've wired the jack detect to the Lino output, i.e. you've mistakenly swapped line and headphone in your circuit.

    Or, maybe it has not really muted the headphone output (how would you know?), and maybe the headphone output is just miswired (or the headphone plug is faulty) and you're just not getting audio out of the headphone connector. 

    Lots of possibilities..
