Android Things Raspberry pi 3 jack 3.5mm not working

Question

I implemented an application run on Raspberry Pi 3 using Android Things. This application will be able to play rtsp video and output to screen via HDMI port. But the audio is not working with jack 3.5mm. Below is my code:

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        VideoView videoView = findViewById(R.id.video_view);
        videoView.setVideoPath("rtsp://wowzaec2demo.streamlock.net/vod/mp4:BigBuckBunny_115k.mov");
        videoView.start();
    }
}

How can I fix it?

The problem is that if you connect the hdmi first, it will use the hdmi as the audio output.

Try connecting the audio jack first. This solved it for me.

Add this line in config.txt file:

hdmi_ignore_edid_audio=1

If you cannot get the 3.5" jack working, Android Things also supports USB audio as well. A viable solution might be to just get a $7 USB audio card that has 3.5mm jacks on it, something like this:
