How to Fix Teams Room audio cuts out

Last reviewed

Error message

Audio from a Microsoft Teams Room drops momentarily or for extended periods during a call.

Audio is more sensitive to network jitter than video. A 5% jitter rate that you barely notice in video will produce constant audio dropouts.

What this error means

The room sends or receives gaps of silence, choppy audio, or robotic-sounding speech during meetings.

Why this happens

Network jitter is the leading cause. Other causes: AEC (echo cancellation) misconfiguration, dual mic devices fighting for the default, or USB power issues on the speaker bar.

Quick fix (for end users)

  • Power-cycle the Teams Rooms hardware.
  • Test from a different network — tether to a phone if possible — to rule out the local network.

Admin / engineer fix

  • Check Call Quality Dashboard for jitter and packet loss on the audio stream specifically.

  • Make sure UDP 3478–3481 is unfiltered to Microsoft 365.

  • Confirm only one capture device is enabled in Windows recording devices — two enabled mics can cause AEC fighting.

  • Update peripheral firmware. Audio drop bugs in mic arrays are common and usually fixed in newer firmware.

Step-by-step fix

  1. Reproduce and capture timestamp.

  2. Pull CQD data for the meeting.

  3. Address jitter source or peripheral issue.

Still broken? Try these

  • Listen to the meeting recording — does the dropout exist there too? If only one side hears it, it's transmit-side.
  • Capture a packet trace during the call to confirm packet loss.
  • If the room is on Wi-Fi, switch to wired Ethernet.
