Trouble closing audio session

[appcapsergen]

Documented behaviour

Could not find what it's about, it doesn't give an error, the behavior I want just doesn't happen.

Actual behaviour

In my Flutter app the user is able to play a video, I use the chewie package for this. This player uses a VideoPlayerController (from the video_player package) to somewhat control the video player, which ultimately allows me to use the audio_service package to create an audio session. I use this to continue playing the video when the app is paused (in the background or when the phone is locked).

The problem I'm faced with now is that when I've started a video with background audio playback successfully, but then want to close that video, I can't seem to get the audio session to stop as well. This is especially visible on iOS (like in this screenshot), where the media player stays active even though I shut down the video and attempted to shut down the audio session as well.

Runtime error

There's no error.

Reproduction steps

1. Use the audio handler I provided.
2. Start a video, at least with a videoController, with an audio session using the audio handler.
3. Make sure the media controls appear in the notifications centre.
4. Close the video by closing the video or closing the entire screen (if applicable).
5. You can still see the media controls in the notifications centre.

### Devices exhibiting the bug
At least on iOS 16.7.5, pretty sure it's on any iOS version though.

I can't seem to get the audio session to stop as well

Do you mean the audio service? The audio session is handled by a separate package.

This is especially visible on iOS (like in this screenshot), where the media player stays active even though I shut down the video and attempted to shut down the audio session as well.

I don't see any provided screenshot, and I am also not sure what you mean by "the media player". Do you mean chewie? Or do you possibly mean the player in the notification or control center?

If you're talking about the notification or control center, can you confirm whether this issue only happens when using chewie or video_player, and does not happen with the official example/s in this repo?

[ryanheise]

I just checked through the source code of video_player and it doesn't seem to contain any code that conflicts with my own code for the notification / control center, but it does have code that could potentially conflict with the audio session. So I think I need you to clarify if you really mean the issue is on the audio session side of things.

@ryanheise My apologies, here's the screenshot I do mean the media controls in the notifications enter of an iOS device, yes!

I will test it out now with your example, but I do assume it is the audio session side of things simply because I am able to stop the video, just not the audio (session) of the video that I linked together with this package. (Both chewie and this package can use a video_player for playing of a video or audio respectively)

I found the issue and it was honestly pretty stupid (of me) :P Basically, all I needed to do was call await super.stop(); in the overriden stop method in my custom audio handler... That solved it 🤦🏼‍♂️
