Fixes for the most common Yealink CP50 problems, from the quickest checks to when to contact Yealink. Start at the top: most issues are a setting, a cable or firmware.
What the CP50 has
Check the problem against what this model actually has:
- Microphones: 8-element omnidirectional array
- Connectivity: USB to PC/OPS; Ethernet to Yealink terminal or UVC camera
- Expansion: Daisy-chain up to 8 mics with CPE40 over PoE cable
Quick checks
- Restart the device: unplug power for 30 seconds, then reconnect.
- Reconnect the cables, using the ones that came in the box.
- Check that the CP50 is selected as the microphone and speaker in Teams, Zoom or Meet.
- Update the firmware. How
No sound or people can't hear you
- Check the device isn't muted (look for a red mute light).
- In the meeting app, select the CP50 as both microphone and speaker.
- Check the volume on the device and on the computer.
- Move laptops and their fans away from the microphones.
Echo or feedback
- Make sure only one microphone and one speaker are active in the room: mute laptops that also joined the meeting.
- Don't run the room's audio through both the device and the TV speakers at the same time.
- Hard, bare rooms reflect sound. Rugs, curtains or acoustic panels reduce echo a lot.
- Update firmware: echo cancellation improvements often come in updates.
Keeps disconnecting or drops out
- Use the original cable and a direct port on the computer; long or cheap USB extensions cause dropouts.
- Turn off USB power saving on the computer (Windows: Device Manager → USB Root Hub → Power Management).
- Use wired Ethernet rather than Wi-Fi, and check the switch port for errors.
- Update firmware and the meeting app.
When to contact Yealink
