The iOS microphone recording indicator

Understand how the iOS microphone recording indicator works with Vivox.
Read time 1 minute
Last updated 8 months ago
iOS displays the red bar/orange dot recording indicator while the microphone is in use. When an iOS device is muted by using 
vx_req_connector_mute_local_mic
, the Vivox SDK accesses the capture device (microphone) but does not collect or transmit any audio. This results in the recording indicator displaying.
To hard mute and prevent the recording indicator from displaying, set the capture device to No Device:
int request_count;vx_req_aux_set_capture_device_t *req;vx_req_aux_set_capture_device_create(&req);req->capture_device_specifier = vx_strdup("No Device");vx_issue_request3(&req->base, &request_count);
To unmute, set the capture device to Default Communication Device:
int request_count;vx_req_aux_set_capture_device_t *req;vx_req_aux_set_capture_device_create(&req);req->capture_device_specifier = vx_strdup("Default Communication Device");vx_issue_request3(&req->base, &request_count);
Note
Hard muting or unmuting causes a brief interruption to all audio that is playing from the device.
