I am working with IMX6 SabreAuto Board. I tried connecting my headphones with 3.5mm jack to board's Audio Out J26-3 and was not able to hear any audio. I was able to insert the headphone jack in red slot ,but unable to insert it in white slot.
Is the common 3.5 mm headphone jack appropriate for board? If not, what should be done to hear the audio?
We also tried measuring the output of Audio through multi-meter in Hz, and we were getting frequency variations while playing the audio.
