I was working on audio bring up on i.MX6 based custom board. There is only one audio jack in our hardware design, where in i have routed mic in, mic bias, hp out and line out for the same. I am able to record with a 3 pin headphone
( with builtin mic ). But when i play mp3 or any wav file with the same 3 pin headphone connected there is no proper(clear) audio
when i play mp3/wav with a 2 pin headphone connected, the audio is very clear!! What might be the issue for this? Does anybody has any idea on this?
