Record audio with phone, but play record through bluetooth headset in iOS

Is it possible to record sound with the phone but force the playing through a bluetooth headset?

This is how I set my AVAudioSession category

try AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayAndRecord, with:[AVAudioSessionCategoryOptions.mixWithOthers])

The record is forced to use the phone mic. However, when playing the sound, it comes out from the phone too. I want the sound to be played only through the bluetooth headset.

I tried overriding the output audio port

try AVAudioSession.sharedInstance().overrideOutputAudioPort(AVAudioSessionPortOverride.none)

but still didn't work.

Solution

  • The problem has been solve. I just added the allowBluetoothA2DP option then it works.

    try AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayAndRecord, with:[AVAudioSessionCategoryOptions.allowBluetoothA2DP, AVAudioSessionCategoryOptions.mixWithOthers])
