Hi,
I am designing a device which will have to output audio to headphones. I have chosen the CS42L51 audio codec to do the work but I am concerned about audio coupling. I have a dev board (SAM V71 Xplained Ultra Evaluation Kit) where audio coupling occurs and it's something I can not stand. I have created an audio file using Audacity which only outputs sounds to the left channel and I also used this video: https://www.youtube.com/watch?v=hTvJoYnpeRQ in order to test this in my z1 compact phone, my mac book pro and an iPod Touch 6th gen. The results are that audio coupling also occurs on my phone, minimal compared to the dev board but it occurs.
How one can do a proper design to avoid that?
