ValidateRequiredFields: Unknown selected data source for Port Speaker (type: Speaker)

I am using Chirp SDK for ultrasonic in xcode10.1. I am getting this warning message in log multiple times :

[avas] AVAudioSessionPortImpl.mm:56:ValidateRequiredFields: Unknown selected data source for Port Speaker (type: Speaker)

I tried the below one 

let audioSession = AVAudioSession.sharedInstance()  

    do {  
      try audioSession.setCategory(AVAudioSession.Category.playAndRecord, mode: .spokenAudio, options: .defaultToSpeaker)  
      try audioSession.setActive(true, options: .notifyOthersOnDeactivation)  
    } catch {  
      print("audioSession properties weren't set because of an error.")  
    }

But still shows warning for me. How to fix this warning.Thanks in advance

Solution

  • Dan from Chirp here. Unfortunately, this warning is a known issue in the current Chirp iOS SDK (3.4.3) on certain devices and it can't be remedied by code on the user side. It's scheduled to be fixed in the next release, due out in the next few weeks. It is benign, however, and won't affect functionality.
