Problem with microphone with camera inactivated

Versions 2.24 and 2.25
When connecting from a mobile device to the web video call, if the camera has not been activated, the microphone does not work correctly, the voice is recognised only for subtitles, but the participant’s voice is not heard, the microphone status icon (stausMic) detects that it is spoken. After activating the camera, the voice is heard correctly. Tests have also been done with OpenviduCall with two and three participants, and in most tests it does not work correctly (demos.openvidu).
