Notification sound not playing on Android

[LaxmikanthMadhyastha]

Describe the bug Notification sound not coming in the example app I downloaded the example project and ran it on my OnePlus 7 Pro directly without modifying any code using the flutter run --release, when I click on any of the options on the main page, the notification appears on the notification panel, but there is no default sound being played or the custom sound being played upon clicking the button

PS: I have disabled the battery optimization option as well

One thing I observed is that when the notification appears on the notification panel and upon long-pressing the notification, it shows the importance of that notification as Others though in the example project priority is set to high and importance is set to max (Image 1).

If I got to app settings and view the settings for that notification channel it still says Important

However, if I click on Others and then click on Important again in the above picture then the notification sound plays

I have attached a screen recording for better understanding.

To Reproduce

1. Clone the example repo
2. Click on "Show notification with custom sound "
3. Notification will come but without any sound

Expected behavior Notification should come with custom sound

PS: Even other notifications also appearing without the default notification sound

Facing same issue Works fine for samsung devices but not for OnePlus :(

This is something you would need to research on when it comes to Android OEMs doing their own custom implementation of Android as these issues are outside the control of this plugin. It might be they require other settings to be changed but because other OEMs are applying customisations, it's not part of the standard Android OS that there'd be APIs for it. If you run this on stock Android devices e.g. emulator, Pixel phones it works fine. So to summarise, there's nothing that can be done on the plugin side.
