I just bought myself an iPad to take notes with Notability so that I can record my teachers' voices along with my notes, for this upcoming summer semester. Now with the mandated lock down, all my summer classes will be taking place online with Zoom.
To try to still be able to record them while taking notes (without having to play the sound out loud), I bought myself a TRRS cable. I connected one end to the MacBook earphone jack and the other end to the iPad earphone jack. (Inspired by this Cult of Mac article: How to record any audio on your iPhone).
However, when I try recording sound coming from my Mac, here is what my iPad is picking up:
Any ideas what could be causing this?
