iOS Error - Audio Cache - Audio causing entire app to lag/hang

[kbessemer]

I have verified this flutter plugin is causing the issue, as removing all audio calls have resolved the issue.

Full Description My app involves changing screens regularly, I am using Navigator.push and Navigator.pop, lots of button presses all with audio using this plugin. After a couple minutes of using the app it starts to lag and eventually freezes before continuing.

Code to Reproduce final player = AudioCache(); playClick() async { player.play('click.wav'); }

same problem here, massive lag and freeze

Same here with 0.20.1, I tried upgrading to 1.0.0 but now the audio play only one time. Is there any updates ?

For context: I'm trying to play a sound on button click. If this button is clicked too many times in a fast way, the app start to lag and may crash on IOS.

Same here, 0.20.1 too, using it as dependency of flame_audio (which doesn't do a lot - it's just a wrapper).

From AVAudioSession.h:

typedef NS_ENUM(NSInteger, AVAudioSessionErrorCode)
{
    ...
    -->**AVAudioSessionErrorCodeMediaServicesFailed**<--          = 'msrv',           /* 0x6D737276, 1836282486   */
...
}

AVAudioSessionErrorCodeMediaServicesFailed:

An error code that indictates an attempt to use the audio session during or after a Media Services failure.

And as I understand, Media Services failure may be this from OP's logs (I got the same):

2022-06-02 04:39:17.968175-0400 Runner[1305:456126] [default] CheckRPCError: AudioSessionSetProperty_Priv returned server mach error 0x10000003!

Now a bit more context for my case. How I use it:

_firstPrioritySfxPlayers[sfx] = AudioCache(...)
...
if (_firstPrioritySfxPlayers[sfx] == null || _firstPrioritySfxPlayers[sfx]!.state != PlayerState.PLAYING) {
    _firstPrioritySfxPlayers[sfx]!.play(file, volume: volume, mode: PlayerMode.LOW_LATENCY);
}

I do not run sounds with the same source simultaneously (at least don't want), and for this case I have 6 different sounds.

Can you retest with audioplayers: ^1.1.0 ?
