I have a Mid 2011 MacBook Air that I want to connect an external microphone to. It looks somewhat like the first picture below, except that it has one ring on the audio jack instead of the usual three.
So, I have purchased a splitter cable, like the second picture below, with three rings so that my MacBook would recognize the mic.
When I go into System Preferences > Sound > Output it says Headphones are inserted into Headphone Port, which is correct. Unplugging it turns it back into the default Built-in Internal Speakers. However, under audio input it still says it is using the Internal Microphone. Other sound programmes such as Adobe Audition also do not recognize the mic, but recognize the speakers plugged in. Why is this so?
Note: The cable and the microphone work perfectly on a PC, so there are no problems with the splitter cable and/or the microphone.
