Polystudio USB causes echo on far end

[DaleKaye]

We are running a class from two locations, the instructor's location Dell Optiplex 7010 mini is running Windows 10, and this end with only students in running a Dell Optiplex 7010 mini with Windows 11. 

When connected to a Teams meeting with my Polystudio USB connected to a Dell Optiplex 7010 mini, with Windows 11 installed on it, the far end (using Polystudio USB with Windows 10 on the PC) starts to get a bad echo after an 90-120 minutes or so.  This setup worked without issue for a couple of weeks, but we started getting the echo issue on Tuesday Oct 1, and it started getting really bad on Wednesday Oct 2.  Once the echo starts, rebooting both computers allows the class to continue without an echo for another 90-120 minutes.  If we mute the mic on the Windows 11 end, the echo stops, but the instructor likes the mic on the Windows 11 end to stay live for comments/questions. 

I've got a Windows 10 PC in the classroom that has run for an hour this morning with no issues.

 I did see this article, https://h30434.www3.hp.com/t5/Webcams/Poly-Studio-USB-MS-Teams-echo-on-Windows-11/td-p/8944929 but both Polystudio USBs are updated to the latest firmware (2.1.2.0001179)

Hi @DaleKaye Welcome to Poly HP Support Community.  
 

I’m sorry to hear about the issue you’re facing with the Poly Studio USB. I understand how challenging this can be, especially during important training sessions. To help resolve the problem, please follow these troubleshooting steps:

1. Audio Settings: Check the audio settings on both ends to ensure that the microphone and speaker volumes are appropriately set. Excessively high levels can contribute to echo.

2. Device Drivers: Make sure that the audio drivers for the Poly Studio USB and the Dell OptiPlex PCs are up to date. Outdated drivers can lead to performance issues.

3. Firmware Update: Use the Poly Lens application to check for and install any firmware updates for your Poly Studio USB. Keeping the firmware up to date can enhance performance and resolve compatibility issues.

4. Network Stability: Since the echo seems to occur after 90-120 minutes, it may be related to network stability. Check the network connection on both ends to ensure it is stable and sufficient for video conferencing.

5. USB Connection: If possible, try connecting the Poly Studio device to a different USB port. Sometimes, changing the port can help resolve connectivity issues.

6. Feedback Loop: Since muting the microphone on the Windows 11 end stops the echo, consider repositioning the microphone or speakers to minimize feedback. Make sure the microphone isn’t picking up sound from the speakers.

7. Testing with Different Software: If the problem persists, try using different video conferencing software to see if the echo issue is specific to Teams.

If you continue to experience difficulties after trying these steps, please don’t hesitate to reach out for further assistance. I’m here to help!
