Hi @Ejaz Chunawala,
Thank you for posting your question in the Microsoft Q&A forum.
Based on your description, when you run Make a test call in Microsoft Teams, the automated voice message plays twice in sequence. I genuinely recognize the impact on quick audio checks and I appreciate the time you have taken to test and report this new behavior.
This behavior commonly occurs when audio is routed to more than one output device or when system or driver enhancements duplicate the playback. It may also appear after a recent Teams or audio driver update if cached media components did not refresh correctly. Therefore, the steps below focus on isolating the audio path and refreshing Teams media components so that the prompt plays only once.
Below are a few practical solutions that could best fit your current needs:
1/ Set a single, consistent audio path
- In Teams, go to Settings > Devices. Set Speaker and Microphone to the same physical device, for example your USB headset. Turn Secondary ringer to Off.
- In Windows, open Settings > System > Sound. Under Choose where to play sound, keep only one active output during the test.
- Then select More sound settings > Playback > Properties. Set Spatial sound to Off and, on the Enhancements tab, disable audio enhancements if available.
2/ Refresh the Teams client and clear media cache
- Update Teams to the latest build.
- Quit Teams completely by right clicking the Teams icon in the taskbar and selecting Quit, then close any Teams.exe processes in Task Manager.
- Press Windows + R, then type: %userprofile%\appdata\local\Packages\MSTeams_8wekyb3d8bbwe\LocalCache\Microsoft\MSTeams, and delete these folders if present: blob_storage, Cache, databases, GPUCache, IndexedDB, Local Storage, tmp.
- Relaunch Teams, sign out, sign back in, and run Make a test call again.
3/ Adjust exclusive mode and monitoring settings
- Open Control Panel > Sound > Playback > Properties > Advanced. Uncheck Allow applications to take exclusive control of this device and Give exclusive mode applications priority.
- Go to Recording > Microphone > Properties > Listen. Ensure Listen to this device is unchecked.
- Additionally, temporarily disable any third party audio suites such as Dolby, DTS, Nahimic, or SteelSeries Sonar, then test again.
4/ Isolate with the web client and refresh audio drivers
- Test in Teams on the web by opening Microsoft Edge InPrivate, going to https://teams.microsoft.com, then navigating to Settings > Devices > Make a test call. If the prompt plays once on the web, the behavior is limited to the desktop client.
- Open Device Manager, expand Sound, video and game controllers, right click your audio device, choose Update driver or reinstall the vendor driver, restart the device, and test again.
- In the Teams desktop app, you can also try Settings > App > Turn off Hardware acceleration, then restart Teams and retest.
If the message still plays twice after these steps, please share your operating system version, your Teams version from Settings > About > Version, your audio device model, whether the issue occurs in the web test, and the approximate time with time zone of a recent test call. With that information, we will continue the investigation.
I hope this information is helpful. Please follow these steps and let me know if it works for you. If you have any updates regarding the issue, please feel free to share any additional detail informations, as it will help me understand your situation more clearly and continue the investigation with greater accuracy.
Thank you for your patience and your understanding.
I look forward to continuing the conversation. Wishing you a smooth rest of your day.
