Sound not working on raspberry pi with Android Things

Question

Sound not working on raspberry pi with Android Things

We recently rolled Android Things on a Raspberry Pi 3 and everything works great except for the sound. I have tried connecting 3.5mm headphone jack and hdmi screen, and also in various combinations such as:

Headphones only without hdmi display.
Only hdmi monitor.
also plugged in earphone connected to raspberry pi 3.5 audio jack and hdmi display.

I tried all of this with adb command. Example:

adb shell am start -a android.intent.action.VIEW -d file:///sdcard/music/sample.mp3 -t audio/mp3

Alternatively later the code is also used:

MediaPlayer mPlayer = MediaPlayer.create(this.getBaseContext(), R.raw.humma);
mPlayer.setOnErrorListener(this);
mPlayer.start();

But in none of these conditions the sound worked.

Below is the console log:

adb shell am start -a android.intent.action.VIEW

Tells Android about the intention to activate the action VIEW

on "Play mp3". AndroidThings is not like Android AOSP - it has no built-in apps. Therefore it doesn't have an app that can VIEW

play MP3.

To play mp3 in your application, you need to make sure the file is compatible with the system. See here for supported media formats

If that's okay, you have the correct code to play the media file ( more details here ). Then you should check the logs to see if it plays.

I suspect it has something to do with the following audio management API: https://developer.android.com/things/sdk/drivers/audio.html
