. It does not only occurs with youtube, same problem if I launch some games like Subway Surfers . Also the problem does not occur with some apps like on the video preview on twitter feed

Expected result

Audio should stay at the same volume when a video preview with no sound is playing.

Actual result

The volume become noisy and it can be scary sometimes.

I cannot observe this when testing on a Pixel 7a.

Does it happen on the mentioned devices only or can you reproduce on other devices too?
Is using VLC required in the reproduction steps or does it happen with other apps as well (e.g. the Media3 session demo app)?

Oh, I see. Maybe this bug only occurs with OnePlus smartphones 🤔 I actually tried it with my brother's Huawei P30 phone and the bug doesn't occur, so for now, it only happens with the mentioned devices. Using VLC player is not required; I just wanted to make sure it doesn't happen with other players. The bug only occurs with an application using exoPlayer (including the demo application). Also I could precise that the OnePlus Nord is on Android 12 (SDK 31).

Okay, thanks. Does the problem only occur with the YouTube preview? I wonder if either YouTube or the device is modifying the system volume automatically for some reason and then cause the issue you observe. It's also worth checking the system volume sliders for media to see if they change too.

In any case, it sounds like the problem is outside of our libraries and there is no much we can do about it with our code.
