Problem with surround (6 channels) audio with HLS on android 10 & 11

[ParhamBandarchi]

What version of Hls.js are you using?

v1.0.7

What browser and OS (including versions) are you using?

Chrome and Opera on Android 10 & 11

Configuration:

We have tested this on the demo page as well to be sure as well without any modifications but still no luck

https://hls-js.netlify.app/demo/

Steps to reproduce

We noticed a strange problem recently when our customers started reporting problems with audio on android, after gathering more information we found out that this only happens when the audio of the hls file is 6 channels/surround and there are using android 10 or 11 with chorme or opera (it works fine on firefox on both android 10 and 11)

on Android 10 you can't hear the dialogue properly (it's too quite compare to other sounds) but you can hear all the other noises normally

on Android 11 all of the noises have some kind of crackling on them and you can't understand what they are saying

Expected behavior

Should be able to hear everything clearly and normally

Actual behavior

Android 10 - dialogue are too quite Android 11 - crackling noise

Console output

There are no errors

This doesn't seem like an HLS.js specific issue. Have you reported this issue to the Chromium team? Still need a functioning stream to reproduce the issue. Additional Android device and platform information would also help.

Browser Mozilla firefox 5.1 channels are working

Removing the v1.5.0 milestone as valid sample that I can access have not been provided. We also haven't isolated what audio codec(s) are at play here.

See related issue #5162 for more information on issues with mult-channel audio in Chrome and recommendations (avoid multi-channel AAC in browser).
