To know if the phone is muted

Hi All!

I think it’s a common problem, but couldn’t find the solution.
If the phone is muted, we can still hear sounds in a game. How to know if the phone is muted using only Unity and C#? Don’t want to add any plugin, because I think Unity must be able to solve such problems.

Thanks!

Sorry, but nobody knows? Do you really release your games with such a terrible bug?
