Android 14: Failed to set playback params: arguments out of range

That error is coming from the framework AudioTrack saying it does not support the values that you try to set. See JavaDoc here.

I guess this does not happen if you do not set setEnableAudioTrackPlaybackParams to true. Can you confirm?

Before my setting, the log:
Log.d(TAG, "setPlaybackParams speed=$speed pitch=${playbackParameters.pitch}")
shows: pitch is always 1.0. I tried speed from 0.5 to 2.5, and it doesn't matter what number it is, always got the exception.
If you look at the stacktrace, when I set say speed=1.5, somewhere in the call stack to AudioTrack the number got messed up.

As mentioned in the report, I tested my code on other Android devices, the problem didn't happen. It only happens with my S21 Android 14 device.

And in my code, setEnableAudioTrackPlaybackParams was not called.

I tried to specifically calling setEnableAudioTrackPlaybackParams with:
exoPlayer = ExoPlayer.Builder(context, DefaultRenderersFactory(context).setEnableAudioTrackPlaybackParams(false)) .setTrackSelector(trackSelector) .setLoadControl(loadControl.build()) .build()
And the issue is the same.

Thanks! Can you shed some more light on the configuration under which you are seeing this warning?

1. Is setEnableAudioTrackPlaybackParams set to true?
2. Is the player playing in offload mode when you see this warning?
3. Have you applied some specific customization to buffer sizes when you see this warning?

The easiest way for us to help is with the ExoPlayer demo app. You are saying above it is not reproducible there. Can you explain why or how we can repro in the demo app? The question is again pointing towards whether you have some specific setup of the player that isn't applied in the demo app, else the demo app could repro this as well.

Ok, it has to do with offload.

I built the player with:

       val audioOffloadPreferences = AudioOffloadPreferences.Builder()
            .setAudioOffloadMode(AudioOffloadPreferences.AUDIO_OFFLOAD_MODE_ENABLED)
            .setIsGaplessSupportRequired(true)
            .build()
        exoPlayer = ExoPlayer.Builder(context, DefaultRenderersFactory(context))
            .setTrackSelector(trackSelector)
            .setLoadControl(loadControl.build())
            .build()
        exoPlayer.setSeekParameters(SeekParameters.EXACT)
        exoPlayer.trackSelectionParameters = exoPlayer.trackSelectionParameters
            .buildUpon()
            .setAudioOffloadPreferences(audioOffloadPreferences)
            .build()

So that has the problem.

Now I changed it to:

        val audioOffloadPreferences = AudioOffloadPreferences.Builder()
            .setAudioOffloadMode(AudioOffloadPreferences.AUDIO_OFFLOAD_MODE_ENABLED) // Add additional options as needed
            .setIsGaplessSupportRequired(true)
            .setIsSpeedChangeSupportRequired(true)
            .build()
        exoPlayer = ExoPlayer.Builder(context, DefaultRenderersFactory(context))
            .setTrackSelector(trackSelector)
            .setLoadControl(loadControl.build())
            .build()
        exoPlayer.setSeekParameters(SeekParameters.EXACT)
        exoPlayer.trackSelectionParameters = exoPlayer.trackSelectionParameters
            .buildUpon()
            .setAudioOffloadPreferences(audioOffloadPreferences)
            .build()

by adding setIsSpeedChangeSupportRequired, then the exception doesn't occur, and play speed is set correctly on the S21.

Anyhow, if anyone wants to check about the program, my project Podcini is open source at https://github.com/XilinJia/Podcini.
