如何更改AVCaptureSession音频音量？

let captureSession = AVCaptureSession()

// 配置音频输入
guard let audioDevice = AVCaptureDevice.default(for: .audio),
      let audioInput = try? AVCaptureDeviceInput(device: audioDevice) else {
    // 处理无法获取音频输入设备的情况
    return
}
if captureSession.canAddInput(audioInput) {
    captureSession.addInput(audioInput)
}

// 配置音频输出
let audioOutput = AVCaptureAudioDataOutput()
if captureSession.canAddOutput(audioOutput) {
    captureSession.addOutput(audioOutput)
}

guard let audioConnection = audioOutput.connection(with: .audio) else {
    // 处理无法获取音频连接的情况
    return
}
audioConnection.audioVolume = 0.5 // 设置音量，范围为0.0到1.0之间
