StackOverflow on basic sound playback

[chris-hatton]

When using either artifact...

"com.soywiz.korge:korge-core:5.1.0"

...or...

"com.soywiz.korge:korge-core:6.0.0-alpha9"

...what appears to be a basic Audio Playback usage fails on both JVM and JS (so likely in common code) with the following:

ℹ️ The sound actually does play - the crash seems to occur at completion

JVM Error

Slightly condensed reproduction example (for usage context)

This example shows how I'm trying to use Korge with Jetpack Compose, though the actual Korge/KorAu API touch-points are probably the only significant thing:

@OptIn(ExperimentalResourceApi::class)
@Composable
fun AudioCrashExample() {

    var sound: Sound? by remember { mutableStateOf(null) } // <-- Load sound
    val scope = rememberCoroutineScope()

    // This coroutine loads the sound (appears to work in debug)
    LaunchedEffect(null) {
        val soundBytes = Res.readBytes("files/button.wav")
        val audioData = WAV.decode(data = soundBytes)!!
        sound = nativeSoundProvider.createNonStreamingSound(audioData, "button")
    }
    Button(
        onClick = {
            scope.launch { sound?.play()?.await() } // <-- Trigger sound, this causes the crash
        },
    ) {
        Text("Play sound")
    }
}

Further condensed example

Cutting out the Jetpack Compose code; this is how I'm driving Korge:

val soundBytes = Res.readBytes("files/button.wav")
val audioData = WAV.decode(data = soundBytes)!!
val sound = nativeSoundProvider.createNonStreamingSound(audioData, "button")
sound.play().await()

...this seems to be a simple example. I'm new to KorGE but a quick inspection of the JVM stack trace does make it look like a straightforward bug in its playback state management(?). Am I doing something wrong?
