Zoom meeting no sound — joining a call and hearing nothing while participants are visibly talking — is almost always caused by Zoom sending audio to a different output device than the one you are listening through, or by Zoom not having joined computer audio for the current session. According to Zoom’s support documentation, selecting the correct speaker inside Zoom’s Audio settings and running the built-in speaker test resolves this in under a minute.

Zoom meeting no sound: test speaker in Zoom settings, confirm computer audio joined, check Volume Mixer, set Windows default device, disable audio enhancements, restart Zoom

What causes no sound in Zoom meetings

Wrong speaker selected in Zoom — Zoom remembers the last audio device you used. If you plugged in new headphones, connected a USB speaker, or used a different audio output since the last meeting, Zoom may still be routing audio to the previous device — which is now disconnected or inactive.

Computer audio not joined — Zoom requires you to explicitly join computer audio at the start of each meeting. If you dismiss or skip the audio prompt when joining, you enter the meeting in a listen-only state with no audio connection at all.

Zoom volume muted or at zero — Zoom maintains its own internal volume setting independent of Windows system volume. The Zoom speaker volume can be set to zero inside the app even when the Windows volume is at 100%.

Wrong Windows default playback device — When Zoom’s speaker is set to “Same as System,” it follows the Windows default playback device. If Windows recently switched the default to a device you are not using (a TV connected via HDMI, a monitor with built-in speakers, or a recently disconnected headset), Zoom audio plays to that device instead.

Audio enhancements interference — Windows audio enhancement features — noise suppression, equalizer, virtual surround — can conflict with Zoom’s audio processing pipeline and cause meeting audio to be suppressed or silenced entirely.

How to fix Zoom meeting no sound

Work through the steps in order. Step 1 takes under 60 seconds and identifies the correct speaker for Zoom without leaving the app.

How to verify the fix

After each step, run the Speaker Test in Zoom Settings > Audio. The test chime should play through your intended output device. Then join a Zoom test meeting at zoom.us/test — select “Test Computer Audio” when prompted and confirm you can hear the recorded playback of your own voice.
