I recently noticed that my Note 8 volume is extremely low when listening to audible media. Not when talking on it.
Did this happen after an update? If not, Try checking your speaker for possible blockages in your speaker slots. You can try putting your device into Safe more and seeing if the issue goes away. If it dose its app related and id suggest clearing the cache on all your apps. You can also back up all your data or cloud your data and try factory resetting the device. But id only recommending this as a last resort.
If your phone is misbehaving, it's possible that a third-party app is causing the issue. To figure out what app is acting funny, you can use the Safe Mode feature. In Safe Mode, your phone won't run any third-party apps. This allows you to easily identify and remove the app that may be causing the problem.

Does this happen on all apps or specific apps?
