no input no output in my sounddevices

Question

device not recognised, no sound no input no output

Answer 1

If your sound devices are not recognized and there is no input or output, you can try the following troubleshooting steps:

1. Check Connections: Ensure that all audio devices (speakers, headphones, microphones) are properly connected to your computer.
2. Device Manager: Open Device Manager and check if your audio devices are listed. If they are not listed or have a yellow exclamation mark, there may be an issue with the driver installation.
3. Show Disabled Devices: Right-click in the sound control panel and ensure that both "Show Disabled Devices" and "Show Disconnected Devices" are checked. This will help you see if the devices are simply disabled.
4. Update Drivers: Ensure that you have the latest drivers installed for your audio devices. You can do this through Device Manager by right-clicking the device and selecting "Update driver."
5. Audio Services: Make sure that the Windows Audio and Windows Audio Endpoint Builder services are running. You can check this by typing services.msc in the Run dialog (Win + R) and looking for these services.
6. KSStudio Utility: If you are a developer or have access to it, you can use the KSStudio utility to enumerate filters and check if the audio device is being recognized correctly.

If these steps do not resolve the issue, you may need to look into more specific hardware or driver problems.
