Source-checked About 10 minutes
Answer
Select the correct output, run Windows audio diagnostics, then update, roll back, or reinstall the PC maker's matching Realtek driver.
Check the matching PC-maker audio driver before changing anything
Identify the exact device, app, account, error, and affected feature for the matching PC-maker audio driver. Keep the current result visible or record it first, so the page's later actions can be tested against one clear starting point.
Use the supported controls for the matching PC-maker audio driver
Follow the specific control path in the next steps and change only the setting or component that matches the observed problem. Do not combine resets, driver changes, account changes, or third-party tools before checking the documented route.
Check the selected output
Open Settings > System > Sound and select the intended speakers or headphones.
Run the audio troubleshooter
Use Get Help to run the audio troubleshooter and follow its recommendations.
Choose the matching driver action
In Device Manager update the audio device, or roll back the driver if the issue began immediately after an update.
Reinstall from the PC maker
Uninstall the audio device and restart. If Windows does not restore working audio, install the signed Realtek package from the PC manufacturer's model-specific support page.
Verify the result for the matching PC-maker audio driver
The expected Realtek device and version appear after restart and speakers, headphones, and microphone pass their relevant tests. Repeat the original task once after reopening the relevant app or settings page, so a temporary screen refresh is not mistaken for a completed result.
Narrow down problems with the matching PC-maker audio driver
If the package rejects the hardware, audio becomes a generic device, enhancements vanish, or the same Device Manager code returns, stop broad resets and return to the last known state. Capture the exact error, versions, hardware or account scope, and failed step before using the linked official support channel.

If it does not work
