How can solve E/MediaPlayerNative: error (-38, 0)

Hello everyone.
I just started developing with Kotlin and I’m using mediaplayers and it’s only working when I launch the item first time. From the second onwards I get the error “E/MediaPlayerNative: error (-38, 0)”.

Here is the code:

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.soundpage)

        val guarigione = MediaPlayer()
        val legno = MediaPlayer()
        val urlGuarigione = "https://www.istitutoartusi.it/colazioni/temp/guarigione.mp3"
        val urlLegno = "https://www.istitutoartusi.it/colazioni/temp/guarigionelegno.mp3"

        guarigione.setAudioAttributes(
            AudioAttributes.Builder()
                .setContentType(AudioAttributes.CONTENT_TYPE_MUSIC)
                .build()
        )
        guarigione.setDataSource(urlGuarigione)
        guarigione.prepare()

        legno.setAudioAttributes(
            AudioAttributes.Builder()
                .setContentType(AudioAttributes.CONTENT_TYPE_MUSIC)
                .build()
        )
        legno.setDataSource(urlLegno)
        legno.prepare()

        btnPlay1 = findViewById(R.id.btnPlay1)
        btnPlay1.setOnClickListener{
            stopAudio(legno, btnPlay2)
            playAudio(guarigione, btnPlay1)
        }

        btnPlay2 = findViewById(R.id.btnPlay2)
        btnPlay2.setOnClickListener{
            stopAudio(guarigione, btnPlay1)
            playAudio(legno, btnPlay2)
        }
    }

    private fun playAudio(musica: MediaPlayer, bottone: ImageButton) {
        musica.setLooping(true)

        if (musica.isPlaying())
        {
            bottone.setImageResource(R.drawable.play)
            musica.pause()
        } else {
            bottone.setImageResource(R.drawable.pause)
            musica.start()
        }
    }

    private fun stopAudio(musica: MediaPlayer, bottone: ImageButton) {
        if (musica.isPlaying())
        {
            bottone.setImageResource(R.drawable.play)
            musica.stop()
            musica.reset()
        }
    }

I start the first song and it works.
I start the second song and the application stops the first one and starts the second regularly.
When I try to start the first song again it doesn’t start and I get the error E/MediaPlayerNative: error (-38, 0).
Can anyone help me fix this error please?
