My guess:  
First run: Your last line of the code you posted does the same as the line before, but outside of the `then` which doesn’t work as the preloading is not finished yet.  
Later runs: You can’t preload the same ID multiple times. You should probably check if it is already preloaded by catching the error in the Promise.

How is first run error solution?

```auto
this.platform.ready().then(() => {
			this.nativeAudio.preloadComplex(.....,....., 1, 1, 0)
						.then(() => {this.nativeAudio.play(.....);});}

```

That has nothing to do with the thing this topic is about - specific error messages. Please open a new topic for this if you haven’t done so already.

First run: Your last line of the code you posted does the same as the line before, but outside of the then which doesn’t work as the preloading is not finished yet.

I mean I don’t need to write the last line

```auto
this.platform.ready().then(() => {
			this.nativeAudio.preloadComplex(.....,....., 1, 1, 0)
						.then(() => {this.nativeAudio.play(.....);});

```

but after come to same page.its dont work

I’m used to

```auto
this.nativeAudio.preloadComplex(..................,................, 1, 1, 0);

```

But same id [error.So](http://error.So) on Leave page

```auto
this.nativeAudio.unload(..........);

```

`unload(id)`==\>Unloads an audio file from memory
