Microphone On Apple Watch Not Working
If your microphone isn’t working on your Apple Watch, there are a few things you can try to fix the problem. First, make sure that your watch is not in silent mode. You can check this by looking at the top of your watch face – if there is a red dot next to the silent mode icon, your watch is in silent mode and you will need to disable it in order to use the microphone.
If your watch is not in silent mode, the next thing to check is the microphone itself. You can do this by opening the Control Center on your watch (swipe up from the bottom of the watch face) and tapping on the microphone icon. If you see a red slash through the icon, this means that the microphone is muted and you will need to unmute it in order to use it.
If neither of these solutions solves the problem, you may need to restart your watch. To do this, press and hold the side button until you see the power off slider. Drag the slider to the right to power off your watch, then press and hold the side button again to turn it back on.
