For test you can use this audio https://archive.org/download/tom_sawyer_librivox/TSawyer_01-02_twain.ogg

To prevent unloading I tried this:

chrome.runtime.onSuspend.addListener(() => {
  (function _doNotSleep() {
    if (audioCurrent) {
      setTimeout(() => {
        fetch('localhost/i-am-not-a-sleep'); 
        console.log(1);
        _doNotSleep();
      }, 1300);
    }
  })();
});

Without success. Can you suggest some workaround?

The documentation says chrome.runtime.onSuspend is only for a quick synchronous cleanup.
It can't prevent a suspend.

Try using your _doNotSleep function without the listener.

Thank you, _doNotSleep() outside of the listener prevent unloading - but not with console.log() but with fetch().

I found that for preventing of unloading in the background I can do only fetch() to some resource but this is not a good solution to leave such code for production - even making GET to the localhost can accidentally run some process on the user machine.

I found that instead of GET to some web resource or even localhost I can make `fetch(chrome.runtime.getURL('manifest.json'))` that is safe and also prevent unloading.

Tested this issue using #59.0.3071.115 on Mac 10.12.5 and was unable to reproduce the issue as per the steps mentioned in comment #0.

@vitaly: Could you please find the attached screen cast and let me know if we missed any steps from our end. If possible please attach a expected screen cast for further triaging of the issue.

Thanks!!

`
Steps to reproduce the problem:
Create event page that plays audio through new Audio(src).play()
`

...I wrote code snippet to reproduce such case but now audio playing without a problem... I will try again in a few days...

I found that this reproducible not with every audio file but from few...

The code is:
manifest.json:
{
    "name": "test",
    "version": "11.07.2017.1",
    "manifest_version": 2,
    "background": {
      "scripts": ["eventPage.js"],
      "persistent": false
    },
    "permissions": ["contextMenus"]
}



eventPage.js:
chrome.contextMenus.create({
  title: 'title',
  id: 'myContextMenuItem',
});

chrome.contextMenus.onClicked.addListener(() => {
  new Audio('https://s3-eu-west-1.amazonaws.com/audio-chunks/amzn1.account.AELY2LYX4N7F3RNVAQY6DDZUTWCQ/03887e2377c3babe52260c0941836676/1d2d90fd60261ca6db0b9f7f2e7d7b49').play();
});

Requesting Blink>Media>Audio team for further triaging of the issue.

Thanks!!

+extensions folk. I have no idea.

Could you please provide any Test URL with the test case from C#12 for easier repro and for checking if this has regressed or not.

no response from reporter@ for > 1 month. no test url is provided. close it.

I am sorry to be late, test url for audio: https://s3.amazonaws.com/intelligentspeaker--audio/04cfff7c02b4d47592d8c4937dee90b5/04cfff7c02b4d47592d8c4937dee90b5

Sorry again, here is the link for the longer audio - better for tests - because on the short audio extension may not be unloaded during playing.

https://s3.amazonaws.com/intelligentspeaker--audio/07997975f557798a53a2ebcd83c56a31/5e4575652578620715ca28697ff2024c

I tested again on macOS, Google Chrome Version 61.0.3163.79 (Official Build) (64-bit) - problem still here.

For easier reproducing you can use this minimal test extension - like the code above but with better naming and with alert() inside onSuspend().

Able to reproduce this issue on Ubuntu 14.04, Windows-10 and Mac OS 10.12.6 using chrome latest stable #62.0.3202.75. Installed the test extension provided in the comment #22, observed an alert saying event suspended while playing audio.

This issue is seen on older version of chrome #50.0.2624.0 as well, hence marking it as untriaged.

Thanks!

Istiaque: can you take a look?
