Echo problem only when 2+ in meeting

Echo issues like this are pretty common when using external audio sources such as a piano or recorded music. The reason you don’t hear the echo but your participants do is that the sound from your speakers (or from your piano) is being picked up again by your microphone and sent back into the meeting — creating a loop. Since the loop happens on your outgoing audio, it doesn’t get played back to you, but everyone else hears the repeated sound.

Here’s what you can try to check:

1. Use headphones or in-ear monitors
   This instantly stops your mic from re-capturing your speaker output — the most reliable fix.

2. Share recordings directly instead of playing them aloud
   Go to Share Screen → Advanced → Share Music or Computer Sound Only.
   This streams clean audio directly to participants and keeps it out of your mic input.

3. Check your Zoom audio settings

   • Turn on Original Sound for Musicians (keep it on for piano).
   • Under Advanced Audio, set:
     • Echo Cancellation: Auto or Moderate
     • Suppress Background Noise: Low
   • If you use an audio interface, make sure monitoring is off or routed correctly so output doesn’t feed back into the mic.

4. Mute extra devices
   If you join from multiple devices, mute the mic and speaker on all but one.

5. Test before your sessions
   Run a short test meeting, record a minute of audio, and listen back to confirm everything sounds clean.

✅ Quick Tip

If echo appears mid-session, try toggling Original Sound off and on again, or quickly switch to headphones.
