Mate 9 speakers problem

[Android Central Question]

Mate 9 has two speakers at the bottom. The left side is working properly but the right side at the bottom is not working propely. What should be the reason behind it?

The Huawei Mate 9 has one speaker at the bottom of the phone.
The sound will come from the one on the right only.
The left side as you face the screen is a microphone.
