What to do if the surveillance is silent on the Xiaomi Smart Camera C302?

If the surveillance is silent on the Xiaomi Smart Camera C302, please refer to the troubleshooting steps:
1. The surveillance feed can be muted because the audio icon is turned off, so tap the mute icon to enable sound playback.
