No sound output through lightning to audio plug adapter
I normally output audio through the lightning connector by way of the lightning to 3.5 mm connector. This has been working for many years and all of a sudden when I plug the lightning connector into the phone the audio on the phone speaker does not cut out and no ordeal is outputted to the audio connector. I have replaced the adapter and tested it on another iPhone and it seems to work fine but it does not work on my phone which is in I OS 8 phone
