When i change input to BluetoothHFP, player is not working.

[anjaeyoung26]

let options: AVAudioSession.CategoryOptions = [.mixWithOthers, .allowBluetoothA2DP, .allowBluetooth]

try session.setCategory(.playAndRecord, mode: .default, options: options)
try session.setActive(true)

if let inputs = session.availableInputs {
    for input in inputs {
        if input.portType == .bluetoothHFP {
            do {
                try session.setPreferredInput(input)
            } catch {
                print(error)
            }
        }
    }
}

I set audio session's input to BluetoothHFP for playing and recording music with Bluetooth mic. After changing the input, there is no sound even after restarting the player.
