2019, 21.5 inch iMac. Monterey
I bought this a year ago to replace a similar 2008 iMac, and immediately noted the lack of a dedicated audio 3.5 mm input jack, which the old model had.
The one jack now there is supposed to serve as both input and output, but I can't get it to recognize a source as an input. Going to Preferences> Sound> Input, I see the internal microphone option but no Line In. This is true with a 3-point stereo adapter plugged into it and an analog source (a tape player) providing a 2 channel signal.
I was told at some point I needed to use a 4-point plug (tip/ring/ring/sleeve) of the type used for video sources (2 channels of audio, one of video) for the Mac to recognize it, but using a video cable with that type of plug as an input with two channels of audio connected (and the third one dead) I still don't see it listed as an input.
What's the answer? Thanks.
