NO SOUND DEVICE INSTALLED

HI, I'm Rodirog and I will help you.
You need to reinstall your audio driver from the device manufacturer.

What is your device model or motherboard model?

Follow these steps in Windows 11 to fix “No audio device installed” and the muted volume:

1. Check the output device and volume
   1. Select the Speakers icon on the taskbar.
   2. Select the arrow to the right of the volume slider and make sure a valid output device (speakers/headphones) is selected.
   3. Open Volume mixer from the same menu and confirm System and app sliders are not muted or at 0.
2. Make sure the device is enabled
   1. Select Start > Settings > System > Sound.
   2. Under Advanced, select More sound settings.
   3. On the Playback tab, select the expected device and choose Properties.
   4. Next to Device usage, ensure Use this device (enable) is selected.
3. Fix missing or faulty audio driver
   1. Open Device Manager.
   2. Expand Sound, video and game controllers.
   3. If no audio device appears or it shows an error, install or repair the driver:
      • Right‑click the audio device > Update driver and let Windows search automatically.
      • If that fails or nothing is listed, download and install the correct audio driver from the PC or motherboard manufacturer’s support site.
   4. If the issue started after a recent update, right‑click the audio device > Properties > Driver tab and use Roll Back Driver (if available).
4. Run the audio troubleshooter
   1. Select Start > Settings > System > Troubleshoot > Other troubleshooters.
   2. Run Playing Audio and apply any fixes it suggests.

If, after installing/enabling the correct audio driver and device, the volume icon still shows “No audio device installed,” it may indicate a hardware problem with the sound chipset or the device connection and requires hardware/vendor support.
