Sped up audio on the web in the first seconds

[yopox]

On the web build of my game, the audio is sped up in the first few seconds on Vivaldi.

Steps to reproduce:

• Run game (itch.io)
• Click on the game during the grey loading screen to enable audio
• On the title screen the music will be sped up for a few seconds

I have used bevy_asset_loader to load my BGMs and SFXs in another state.
In the title state, Handle<AudioSource>-s should be ready and I just call audio.play_looped(songs.title.clone()); on state enter. (loading, audio played)

I have observed that, too. So far I thought this is a general problem of this plugin in the browser (see #9). I have never noticed it in a native build.
The handle being loaded or not does not make a difference I think. The audio will just start playing later.

I will see if bevy_audio has the same issue.

I have observed this less with Bevy 0.7, is it also better for you now?

I'm seeing something that seems related (Bevy 0.7). The first few seconds of my audio are "crackly" before stabilizing. Seems to be the case in Chrome, Firefox, and Safari 🤔. It does seem to be performance related... if I don't setup a camera, so there's nothing for the browser to render, the audio plays fine.

Here's the branch where I'm experimenting https://github.com/shnewto/limbo_pass/tree/wasm-kira

Haven't found the culprit but exploring it did take me into kira and cpal... I saw that the bevy_audio crate's rodio dependency is using the same version of cpal as kira so tested with bevy_audio and the crunch/crackling isn't present 🤔

edit: I missed that you checked bevy_audio already and this isn't news 🙃

edit 2: I've been unable to reproduce the things I thought I was seeing when I used rodio, today using rodio the audio is still plenty crackly.

The problem still occurs with bevy 0.9 and bevy_kira_audio 0.13.0 (example)
