I have a 3rd party SDK that handles an audio recording. It has a callback when the recording starts. In the callback I’m trying to play a sound to indicate to the user that the device is now listening (like Siri, or any other speech recognition tends to do), but when I try I get the following error:

AURemoteIO::ChangeHardwareFormats: error -10875

I have tried playing the sound using AudioServicesPlaySystemSound as well as an AVAudioPlayer both with the same result. The sound plays fine at other times, and per the error my assumption is there’s an incompatibility between the playback and recording on the hardware level. Can anyone clarify this error, or give me a hint as to a possible workaround?

    My problem is related specifically to the external SDK and how they handle the audio interface. They override everything when you ask the SDK to start recording, if you take control back you break the recording session. So within the context of that SDK there’s no way to work around it unless they fix the SDK.
