Do the videos recorded by the Xiaomi Smart Camera C700 have sound?

The Xiaomi Smart Camera C700 records videos with sound, including those saved in the home surveillance, cloud storage, and on the microSD card. However, if you enable fast playback, the audio will be muted by default, which is normal. Additionally, whenever you enter the camera's surveillance footage or access the cloud storage and microSD card video playback interface, the audio will default to mute.
To play the sound normally, please refer to the following steps:
1. Open the [Mi Home/Xiaomi Home] APP;
2. Select the [Xiaomi Smart Camera C700];
3. Press the mute icon in the real-time surveillance footage to restore the audio.
