I'm using iMX6q Android 6.0 and our audio chip wm8958 and codec is wm8994 and a single jack (Like headset[mic+headphone in single jack]) output . In this Mic is not working, Also headphone output is very low.
I did HPOUT gain as High and un-mute it. And also while playing i'm reading the registers Gain is high only. But the output volume is too low.
Can you give your valuable suggestion on this.
1). Jack Gnd connected to AGND but from codec to jack have some filters that connected to DGND. Is this as issue?. Can you confirm this also
