Sound disappears when custom equalizer is enabled

Version

Media3 main branch

More version details

Good afternoon!

On a number of devices with HyperOS,

1. when a custom equalizer is installed, the sound disappears when listening to tracks/switching tracks. If you adjust the volume on the device, the sound is restored.

2. If I add exoplayer::release and create a new ExoPlayer object for each new track, then, judging by messages from users, the sound does not disappear (there is no bug).

3. If the custom equalizer is turned off, the sound does not disappear (there is no bug)

The logs for all three cases contain the same errors.

Sample errors

"W libc : Access denied finding property "ro.vendor.df.effect.conflict"
sample_logs.txt
"

I give errors for the device in attachment

OS: Android 14

Xiaomi HyperOS 1.0.1.0
Poco x5 5g 22111317
Resolution: 2176x1080
DensityDpi:440

i give dependencies

implementation("androidx.media3:media3-exoplayer:1.3.1")
implementation("androidx.media3:media3-ui:1.3.1")

I give code:

private fun createExoplayer() {
    player = ExoPlayer.Builder(applicationContext).build()
    val audioSessionId = player.audioSessionId
    initEqualizer(audioSessionId)
}


@Synchronized
private fun initEqualizer(audioSessionId: Int?) {
    if (audioSessionId == null) {
        stopEqualizer()
        return
    }

    equalizer = Equalizer(150, audioSessionId)

    val shorts = listOf<Short>(0, 0, 0, 0, 0)

    applyBandLevels4AudioSession(shorts)
}


private fun applyBandLevels4AudioSession(bandLevels: List<Short>) {
    val eq = equalizer ?: return
    val minLevel = eq.bandLevelRange[0]
    val maxLevel = eq.bandLevelRange[1]
    val numberOfBands = eq.numberOfBands.toInt()

    if (numberOfBands == 0 || numberOfBands != bandLevels.size) return
    try {
        bandLevels.forEachIndexed { band, level ->
            if (level in (minLevel)..maxLevel) {
                eq.setBandLevel(band.toShort(), level)
            }
        }
        eq.enabled = true
    } catch (e: RuntimeException) {
    }
}

@Synchronized
private fun stopEqualizer() {
    equalizer?.enabled = false
    equalizer?.release()
    equalizer = null
}


//method for playing Track
private fun play(uri: Uri) {


    /*  If you uncomment this the error will go away. But the same errors are written to the logs*/

    // exoplayerRelease()
    // createExoplayer()

    player.setMediaItem(MediaItem.fromUri(uri))
    player.prepare()
    player.playWhenReady = true
}

private fun exoplayerRelease() {
    player.release()
    initEqualizer(null)

}
