如何通过智能手机中多个内置扬声器中的特定扬声器播放音乐？

问：

我的智能手机是 Galaxy S22，主扬声器位于底部，副扬声器位于顶部。 通常，听音乐时，它通过主扬声器播放。

但是，当我使用使用上述代码创建的应用程序播放音乐时，它使用副扬声器。如何解决此问题？无论是通过修改代码还是更改智能手机设置。

我已经探索了与 AudioTrack 相关的各种问题，但没有找到解决方案。

    fun start() {

        val executor = Executors.newSingleThreadExecutor()

        executor.execute {
            val inputFileName = "play.wav"
            val wavfile = File(outputDir, inputFileName)


            if (wavfile.exists()) {
                val audioData = ByteArray(wavfile.length().toInt())
                val fileInputStream = FileInputStream(wavfile)
                fileInputStream.read(audioData)
                fileInputStream.close()

                val sampleRate = 48000

                audioTrack?.play()

                audioTrack?.write(audioData, 0, audioData.size)
            } else {
                // Handle case where file doesn't exist
            }
        }
    }

    fun stop() {
        audioTrack?.stop()
        audioTrack?.release()
    }
