Expected behavior

I expected that I could able to turn on/off the equalizer from the "Equalizer" menu after activating equalizer from settings.

Actual behavior

When I tried to turn on and off the equalizer from the "Equalizer" menu after activating equalizer from the app settings, then the app crashed.

How to reproduce

Here is every possible detail to reproduce the bug.

1. Open the app.
2. Go to "Settings" and enable the "Equalizer".
3. Now click on "Equalizer" that based on the main menu.
4. After that try to disable and enable it and then notice the bug.

• App version: v0.9.4
• Operating system: Android 6.0.1

Possible Fix

I think this crash occurred because of the equalizer option from settings. I believe removing this option from the app would be the easiest way to fix it.
It won't affect the user experience at all because we have another option to use this feature.
