In the blog, USB Type-C audio: Do I need to buy a new pair of headphones?, the crosspoint switch TS3A26746E is mentioned as an alternative to the TS3A226AE which is used in the reference design TIDA-00565, but I am wondering how this could work. How would we be able to detect the position of MIC/GND in order to make the correct crosspoint selection?
Thanks,
Adam
