Can't play sound on iOS

[rafaeleyng]

Description:

I cannot get audio to play on iOS, both on Safari and Chrome.

What I tried:

• autoplay directly on the component. Enable autoplay of sounds for iOS and Chrome for Android #1463 made me think right away that this wouldn't work. But Enable autoplay of sounds for iOS and Chrome for Android #1463 description implies that it wouldn't work for Chrome for Android, but it does work for me.
• using entity.components.sound.play(), both with a setTimeout and with user events.

Both approaches worked properly in Chrome for Android and desktop browsers (Chrome, Safari and Firefox). In Firefox for Android, my app crashes even before I could try the audio, but that is just information, I'm not focusing on Firefox.

I inspected the iOS Safari console and network tabs with remote debug and there wasn't any error or something.

Also, as a side note, I tried the a-wakens demo, and it worked on:

• Chrome, Safari and Firefox (desktop), Firefox (Android)

but didn't work on:

• Chrome (Android), Safari and Chrome (iOS)

So, I'm pretty much clueless about how to get audio to play on iOS and would appreciate some tips.

• A-Frame Version: 0.2.0
• Platform/Device: iOS 9.3.2, iPhone 6, both Safari and Chrome 51

Hi, I moved to http://stackoverflow.com/questions/38645716/cant-play-sound-on-ios because I think this is a question and a matter of figuring out how to use WebAudio on mobile, rather than A-Frame issue.

Thanks @ngokevin

Is there any solution for this problem by now? I have:

• video without sound in iOS Safari
• sound and no video when I pin in it to the homescreen
• video and sound from other sources than the video in Chrome (Dektop)
• no problems in Safari (Desktop)

@antesberger i only get video without sound on iOS Safari. Downloading to homescreen gives me sound and video. I'd check the filesize/encoding of your video maybe?

My big issue is that in iOS Safari even if I write my own sound handlers I get complaints from some global component about the poolSize that I don't get on desktop. @ngokevin is there a default poolSize that gets set only on mobile?

I can't figure out how to identify which entity is playing my random sound (via bubbling up I guess?) and has the default pool size.

Frankly I'm confused as to how Aframe is even aware I'm playing these audio files, as this warning occurs even when the <audio> are outside the <a-scene> and <a-assets> and triggered via JS.

Aframe version 0.5.0

components:sound:warn All the sounds are playing. If you need to play more sounds simultaneously consider increasing the size of pool with the `poolSize` attribute. +8s

Which component is this?
