Hi team, I am using UI Toolkit version @zoom/videosdk-ui-toolkit: 2.1.0-1. I would like to confirm the current behavior: 1/ When I click the mic to open the testing mic, I speak into the mic, and I can see my voice volume changing in the status bar. However, it doesn’t record my voice at that time to play it automatically afterward, right? So, the testing mic is just for me to turn it on, speak, and check the result in the status bar for my changing voice volume? 2/ When I click the speaker, the speaker icon turns on, and I can hear a “ting.” Then, the speaker icon automatically turns off, and there is no further behavior. Is that all for the speaker testing? Kindly help to review and help us reconfirm the above points so that my team can decide the next actions to use the preview screen. Thank you. ---

Hi @Khoa1, we released a new version of the UIKit this month. The latest version of the UITookit is `v2.1.10-1`. With the new version in the precall (preview screen) you have: 1. The ability to record your speech and play it back through the speaker ![Screenshot 2025-03-25 at 4.19.09 PM](https://us1.discourse-cdn.com/flex016/uploads/zoomdeveloper/original/3X/5/2/529866a591907f8a078878b9201f2f991f509bfe.png) 2. The ability to playback a test sound when you click the “Test speaker” button ![Screenshot 2025-03-25 at 4.20.09 PM](https://us1.discourse-cdn.com/flex016/uploads/zoomdeveloper/original/3X/b/c/bc0cf59ecb57f59c30c2be96a4ca08da0e9fa48f.png) ---

Noted for the info. We have updated to the new version and it works as our expectation. We can close this case. Thank you! ---
