The documentation - https://developer.apple.com/documentation/avfaudio/avaudiosession/capturing_stereo_audio_from_built-in_microphones for the Capturing Stereo Audio from Built-In Microphones sample app mentions:
"Starting in iOS 14 and iPadOS 14, you can now capture stereo audio using the built-in microphones on supported devices."
And I saw a specific list of devices that support stereo recording here. - https://developer.apple.com/forums/thread/652770
According to the list, an iPhone11 pro is supported.
But when I run the sample app on an iPhone11 pro, an iPhone 12, or an iPhone12 mini, the supportedPolarPatterns property for the built-in mic data source does not include the .stereo option.
Is there a way to enable it? Or am I using the wrong devices?
