Fixing Microphone and Audio Issues

Sound problems feel alarming, but they nearly always come down to one of three simple things: the microphone permission (your device politely blocking CallTuv from hearing you), the wrong device selected (sound going to or coming from the wrong place), or the internet connection wobbling. Find your symptom below and work through the steps in order - each one takes under a minute.

"The other person can't hear me"

If you're calling from a computer:

1. Check the browser permission. Look at the address bar at the top of the browser - click the small padlock (or settings) icon next to the web address. A little menu opens; make sure Microphone is set to Allow for calltuv.com. If you once clicked "Block" - maybe by accident, months ago - the browser silently remembers, and this is where to undo it.
2. Check the right microphone is chosen. If your computer has several (a built-in mic, a headset, a webcam), the call screen's audio settings let you pick which one to use. Choose the one you're actually speaking into.
3. Check the computer's own permission. The computer itself can also block browsers from the microphone. On a Mac: Apple menu → System Settings → Privacy & Security → Microphone - make sure your browser is switched on. On Windows: Start → Settings → Privacy → Microphone.
4. Do a quick test. Our free mic test tool shows you instantly, with a moving indicator, whether your browser hears you.

If you're calling from the app: check the phone gave CallTuv microphone permission - on iPhone: Settings → CallTuv → Microphone (switch it on); on Android: Settings → Apps → CallTuv → Permissions → Microphone → Allow. Also close any other app that might be using the microphone at the same time (a video call app, a voice recorder), and glance at the call screen to make sure you're not muted - it happens to everyone.

"I can't hear them"

• Check where the sound is going. If Bluetooth headphones were connected earlier and then switched off or wandered out of range, the sound may still be routed to them. Reselect your speakers or headset - on the phone, just tap the speaker button.
• Check the volume - both the device's volume buttons and any volume control on the call screen. It sounds obvious, but it's the answer surprisingly often.
• If there's simply silence, hang up and call again. A network switch mid-call (Wi-Fi dropping to mobile data, a VPN connecting) can silently lose the audio stream - a fresh call fixes it.

"The sound is choppy, robotic, or delayed"

This one is almost never the microphone - it's the internet connection straining:

• Move closer to your Wi-Fi router, or try switching between Wi-Fi and mobile data to find the steadier one.
• If you use a VPN, turn it off for calls - the detour adds delay.
• Pause anything downloading or streaming in the background (videos, large files, cloud backups) while you talk.

If calls keep cutting off entirely, there's a dedicated guide: Calls Keep Dropping or Cutting Off.

"I hear an echo of my own voice"

Echo means your microphone is picking up the sound from your speakers and sending it back. The one-step fix that works nearly every time: use headphones or a headset. Any kind - wired earbuds are perfect.

Still stuck?

If the sound is fine but calls won't start at all, that's a different problem - see Why Your Call Won't Connect. Otherwise, contact us and mention what device and browser you're using and what exactly you hear (or don't) - we'll dig in with you until it's solved.
