We are using imx6qp SabreSD eval board (with OREO 8.0) to make a call. We are able to call the other person, but Not able to hear or speak on the mic port and audio-out port.
We are able play an audio file and listen to it using the audio-out port. We are also able to record the audio using the mic port on the kit. But we are not able to hear or speak after the call connection is established.
