Is there any limit for preloading sounds for prod build on iOS?

The limit for preloading sounds on iOS.

:beetle: What have you tried?

I'm trying to preload more than 300 short sounds via new Sound('file-name.mp3', Sound.MAIN_BUNDLE, () => {}); at the same time, but have no luck loading all sounds. It only loads about 150 sounds and that's it. Also, I would like to mention that this happened for prod build on iOS, but on dev build it works fine.

:beetle: Please post your code:

// sounds = Array<{ title: string; value: string }>

  loadSounds = async (sounds) => {
    const promisifiedSounds = sounds.map((sound) => {
      return new Promise((res, rej) => {
        const currentSound = new Sound(sound.value, Sound.MAIN_BUNDLE, (error) => {
          if (error) {
            console.info('failed to load the sound ', error);
            rej(error);
          }

          currentSound.setVolume(1);

          res(currentSound);
        });
      });
    });

    const data = await Promise.all(promisifiedSounds);

    return data;
  }

Is your issue with...

• iOS

Are you using...

• React Native CLI (e.g. react-native run-ios)

Which versions are you using?

• React Native Sound: ^0.11.1
• React Native: 0.65.1
• iOS: 14.7.1

Does the problem occur on...

• Device

If your problem is happening on a device, which device?

• Device: iPhone 11 (iOS 14.7.1)

Also, I can see an error inside the prod build on xcode console

[javascript] 'failed to load the sound ', { code: 'ENSOSSTATUSERRORDOMAIN-42',

Does anybody know, what does this error means?

I have the same issue as IOS Prod didnt play any sound, but debug works well. Any solution?

[alexeyvax]

I figured this issue out. Instead of loading all sounds after app initialization, just load one sound when the user pressed a play button.

And that's it.

It takes some milliseconds to load your sound but it works perfectly for dev and prod builds.
