how to fix when it says no device found for output or input

Welcome Tina Cribb,

Thanks for reaching out to Microsoft Q&A Forum. I understand that your Windows 11 laptop shows "No output device found" and "No input device found," resulting in both audio and microphone functionality being unavailable.

Could you please confirm:

• Did this start after a Windows update, driver update, or any recent system change?
• In Device Manager, do you see any warning icons next to Sound, video and game controllers or Audio inputs and outputs?

In the meantime, you can try these steps:

Option 1: Check the Windows Audio services

• Press Windows + R, type services.msc, and press Enter
• Locate Windows Audio
• Verify its status is Running
• If it is stopped, right-click it and select Start
• Also verify Windows Audio Endpoint Builder is Running

Option 2: Run the Hardware and Devices troubleshooter

• Open Command Prompt as Administrator
• Run: msdt.exe -id DeviceDiagnostic
• Follow the on-screen prompts

Option 3: Reinstall the audio driver

• Right-click Start and select Device Manager
• Expand Sound, video and game controllers
• Right-click the audio device and select Uninstall device
• Restart the PC and allow Windows to reinstall the driver

Option 4: Check for system file corruption

• Open Command Prompt as Administrator
• Run: sfc /scannow
• After it completes, run: DISM /Online /Cleanup-Image /RestoreHealth

Hi ,

Search for msinfo32.exe in the search bar, take a screenshot, and post it here so we can see the correct laptop model or desktop configuration.

Can you access Device Manager, take a screenshot, and post it here?

Thanks.
