When nobody at the door can hear you
You press to talk, you say hello, and the person on the step keeps pressing the button. This is rarely the doorbell. Most of the time the microphone being used is not the one you think it is, and the first two checks are free and take about a minute.

Work out which direction is broken first
They cannot hear you. You cannot hear them. Neither of you can hear the other. These have different causes and the middle one is almost never the doorbell.
Everything below is faster if you settle this before you change a single setting.
If they cannot hear you
Your voice starts at your phone, so that is where to look. Three things stop it leaving, and none of them is a fault with the doorbell.
- The app does not have microphone permission. Phones grant that separately from camera and notifications, and a major system update can reset it. Open your phone settings, find the app and look at the microphone toggle.
- Your voice is going to your earbuds. If anything is paired over Bluetooth, the phone may be using the microphone in that device. Earbuds in a pocket or a bag pick up fabric and nothing else. Disconnect and try again.
- You are not holding the button long enough. Some apps use press-and-hold to talk and release to listen, so a tap sends nothing at all.
If you cannot hear them
Now the microphone at the door matters, and so does one setting people switch off and forget.
- Audio recording is turned off in the device settings. Most cameras have a privacy control that disables the microphone entirely. It is often switched off deliberately, sometimes by whoever set the camera up, and nothing warns you afterward.
- The microphone port is blocked. It is a pinhole, it sits outdoors, and it collects dust, paint, cobwebs and the edge of a badly fitted cover or wedge. Look at it in good light.
- Your phone is on silent, or the app volume is down. Worth ruling out before anything comes off the wall.
Recording law
Audio is the half that catches people out. Consent laws for recording conversations differ by state, and in some places everyone being recorded has to agree.
Settle whether you may record audio before you switch it back on. Look up your own state's rule, and ask a lawyer instead of a website if anything real depends on it.
If it works but sounds broken
Audio that connects and then breaks up, echoes or cuts out mid-sentence is a different fault from audio that never arrives. It is almost always the connection rather than the hardware.
- Robotic, clipped or dropping words: not enough signal at the door. Voice is the first thing sacrificed when there is not enough to go around, because video gets priority.
- Echo, or hearing yourself back: the phone speaker is feeding the phone microphone. Turn your volume down or use headphones.
- A long delay each way: signal again, and the same fix.
If the fix turns out to be signal
Wi-Fi
TP-Link AC1200 Wi-Fi range extender
A dual-band plug-in extender for the common case where the router sits at the back of the house and the front door is the furthest point from it. Place it midway between the router and the door. An extender repeats the signal it receives, so putting it right at the door repeats a signal that is already poor.
Wi-Fi
TP-Link Deco X20-Outdoor mesh unit
A weatherproof outdoor mesh node, for porches and driveways where an indoor extender never quite reaches and the wall itself is the obstacle. It joins an existing Deco system, so it is the right answer only if you already run one or intend to.
Questions people ask
That points at the door end, and the usual answer is that audio recording is switched off in the device's privacy settings. A blocked microphone pinhole is the other common one. Check the setting first, because it costs nothing.
Some networks are less forgiving of the connection the app opens to carry voice. Test the same call on both, and if only mobile data fails, the doorbell and your home network are both fine.
Often, yes, and it surprises people. A picture that still looks acceptable can sit alongside voice that has stopped working, so signal is worth checking even when the video looks fine.
You can, and on most models it is a single setting. Video of the approach to your own door is rarely the difficult part; audio is. Turning it off is a legitimate choice and not a broken setup.
Not early. It is the most disruptive step and it undoes your settings, wiring notes and any zones you configured. Permissions, the privacy toggle and a Bluetooth check settle most of these and cost you nothing.
If that didn't fix it
Fix guides do not always work first time. If yours did not, the next check depends on what you found.
- Work through it question by question: the interview covers the same ground in order
- If audio breaks up rather than failing: voice goes before the picture does
