Therefore both the input and output will always end up on the Bluetooth HFP device even though only the input or output was set individually. Retrieves the preferred number of input channels. This property returns an NSArray of AVAudioSessionPortDescription objects. A: iOS 6 automatically selects the choice of built-in microphone (on devices that have two or more built-in microphones) through the use of audio session modes. These preferred values are simply hints to the operating system, the actual buffer duration or sample rate may be different once the AVAudioSession has been activated. Retrieves the preferred number of output channels. Save my name, email, and website in this browser for the next time I comment. Use InputAvailable instead. Use OutputNumberOfChannels instead. The data sources available for the current input port. If you assume current values will always be your preferred values and for example fill our your client format using the hardware format expecting 44.1kHz when the actual sample rate is 48kHz, your application can suffer problems like audio distortion with the further possibility of other failures. It is recommended to NOT use the AVAudioSessionSetActiveOptionNotifyOthersOnDeactivation option when going inactive for the purpose of changing some preferred values. Thanks for contributing an answer to Stack Overflow! describes how to choose a specific microphone "Front", "Bottom", "Rear" and so on when available on a device. Instead, I chose the PulseAudio server to fetch available devices on my system. Any advice is highly appreciated. Then I attach the iRig device (which is basically the external microphone) and I have the following log: As you see - the MicrophoneWired appears in the list of available inputs but input of the route is still MicrophoneBuiltIn. Apparently the only way to do this is to fire the aplay / arecord process from Qt, get the result output from the process and parse the output string to find card names and corresponding IDs.
