DOG can't get a sound.

Is it that some people can't receive it, or everyone's voice can't be received?

I suggest you do the following tests:

Step 1: First check whether the software is set incorrectly! !

Step 2: Turn off the phone and restart it.

Step 3: Reinstall the software.

Step 4: It is estimated that there is something wrong with the mobile phone! !

~ I hope my answer is helpful to you. Please continue to "ask questions" if you have any questions!

It's not easy to answer questions and understand each other. Your adoption is my motivation. Thank you! !
