You've got a Wyze Cam v4 mounted and powered on, but the app shows no audio at all, not a single sound from the mic. This is a common pain point, especially since the camera launched in 2024 with 2.5K QHD video but depends heavily on the Wyze app for every control. If music output is the issue that brought you here, let me start with an important reality check: the Wyze Cam v4 doesn't have a built-in speaker for music playback. It captures audio through its microphone and streams it to your phone, but it can't actually play music on its own. If you're trying to listen to audio from the camera's recordings or live feed and hearing nothing, that's a different problem, one I can fix.
Try this first: open the Wyze app and tap on your camera's live feed. Tap the microphone icon in the bottom-right corner to make sure two-way audio is enabled (it should be blue, not gray). Then tap the speaker icon on the camera view to unmute the audio on your phone's end. A surprising number of "no audio" cases are just the phone's camera feed being muted in-app.
Why Audio Might Be Missing from Your Wyze Cam v4
The Wyze Cam v4 captures audio through its built-in microphone, and that audio gets sent to your phone through the Wyze app. But a few things can interrupt that path. Common causes include:
- Microphone muted in the app: the two-way audio toggle in the live view screen can be set to mute without you realizing it.
- Wi-Fi band mismatch: the v4 only works on 2.4 GHz networks. If your phone is on 5 GHz, the connection can suffer even if the camera itself is online.
- App permissions blocked: the Wyze app needs microphone access on your phone to relay audio from the camera.
- Cloud outage affecting live stream: Wyze has had cloud service outages that break live streaming and audio playback entirely.
- Event recordings truncated: without a Cam Plus subscription, cloud video stores only 12 seconds and may cut off audio.
Check the App Permission for Mic Access
Your phone has to allow the Wyze app to use the device's microphone for audio to come through. On an iPhone, open Settings > Wyze and make sure the Microphone toggle is green. On Android, go to Settings > Apps > Wyze > Permissions and confirm Microphone is allowed. If it was blocked, toggle it on, then completely force-close the Wyze app and reopen it. The audio from your camera should start flowing through.
Verify the Camera Is Connected to 2.4 GHz Wi-Fi
The Wyze Cam v4 only works on 2.4 GHz networks. If your router uses band steering (where it pushes devices to 5 GHz automatically), the camera might connect intermittently or drop audio during live streaming. Open the Wyze app, tap the camera's settings gear, then Device Info to see the connected network. If it shows a 5 GHz network or "Unknown," you'll need to re-pair the camera on 2.4 GHz. Create a guest network locked to 2.4 GHz in your router settings if yours doesn't let you separate bands. Then factory reset the camera and re-add it in the app on that network.
Force-Stop and Reopen the Wyze App
Sometimes the app just gets confused, it pulled a stale audio stream and didn't refresh it. On iPhone, swipe up from the bottom and flick the Wyze app card off the screen. On Android, go to Settings > Apps > Wyze > Force Stop. Open the app fresh and tap the live feed. In my experience, a force stop clears up about half the no-audio cases that look like hardware failures.
Power Cycle the Camera
Unplug the USB-C cable from the back of the Wyze Cam v4. Wait at least 30 seconds, the internal capacitors need time to drain. Plug it back in. The camera takes about 45 seconds to boot up and reconnect to Wi-Fi. When it finishes its double-tone chime, open the Wyze app and check the live feed audio. This clears any stuck audio buffer or hung mic state.
Check for a Wyze Cloud Outage
Wyze has had periods where the entire cloud platform went down, killing live streaming and recording playback for every camera. If audio suddenly stopped working and you haven't changed any settings, check down detector websites for Wyze reports. You can also check the Wyze Status page (status.wyze.com), but that page itself may go down during outages. In an outage, nothing you do on your end will fix audio until Wyze restores service on their side. Just wait it out; these outages usually resolve within a few hours.
Make Sure Two-Way Audio Isn't Muted
Inside the live view screen of any camera tile, you'll see two icons at the bottom: a microphone (for the camera's mic) and a speaker (for your phone's speaker). The microphone icon needs to be active (blue on standard theme, or highlighted on dark mode) for audio from the camera to reach you. Tap it once to toggle it on if it's off. Also check that your phone's physical mute switch or silent mode isn't on, that can interfere with the speaker output even when the app thinks it's unmuted.
Factory Reset as a Last Resort
If audio still won't come through after all the steps above, factory reset the camera. Locate the small setup button on the bottom of the Wyze Cam v4 near the USB-C port. Press and hold it for about 10 seconds until the camera's status light starts flashing yellow. Release the button. The camera will reboot to factory defaults. You'll need to re-pair it in the Wyze app: tap the plus sign in the top-left corner of the Devices tab, select Add Device > Cameras > Wyze Cam v4, and follow the pairing prompts. This wipes your camera's network settings, microphone calibration, and any corrupted state that was blocking audio.
