No sound from your computer after upgrading? Don't panic! Are you experiencing problems with your computer suddenly going silent after upgrading to Windows 11? In response to this common problem, PHP editor Yuzai has summarized the possible reasons, including missing devices, missing sound card drivers and unknown errors. To resolve these issues, we provide you with detailed troubleshooting steps. This article will take an in-depth look at the potential causes of no sound on your computer and guide you through step-by-step solutions to the problem.

Solutions to no sound after win11 upgrade:

1. No equipment

1. If we are using a desktop computer, it is most likely because there is no equipment.

2. Because ordinary desktop computers do not come with built-in speakers, we need to plug in speakers or headphones to have sound.

2. The sound card driver is missing

1. After we update the Win11 system, the original sound card or audio device driver may not match, and it needs to be downloaded and installed again.

2. We can click on the start menu, search for and open "windows update settings".

3. Then enter "more options" and select "advanced options".

4. Then enter "optional updates".

5. Find the driver we need to use and click "download&install".

3. Unknown error

1. If it is neither a device nor a driver problem, we can also find the problem through system self-test.

2. First enter the system settings.

3. Then click "Sound" on the right.

4. Then click "Output Device" in the advanced menu below to troubleshoot common sound problems.

5. Finally, wait for the system to automatically detect and solve the problem.
