How to update audio drivers
Audio can come from an internal codec, a graphics adapter over HDMI or DisplayPort, a USB interface, or Bluetooth. These paths may use different drivers. Select the intended playback and recording devices and reproduce the fault before looking for a package.
Check mute, volume, privacy permission, cable, pairing, and application endpoint first. For a laptop or prebuilt PC, the complete-system maker is usually the safest source for model-specific sound processing.

Key Takeaways
- 1
Separate speaker output, microphone input, HDMI audio, USB audio, and Bluetooth.
- 2
Use Windows Update or the exact computer, motherboard, or audio-device maker.
- 3
USB and Bluetooth audio may already use operating-system class support.
- 4
Test permissions and the selected endpoint after restarting.
Identify the playback path
Select the intended speakers, headphones, monitor, or HDMI output in sound settings. Check mute, volume, cable seating, Bluetooth pairing, and whether the application selected a different endpoint. Test a second application so an app setting is not mistaken for a system-driver fault.
For HDMI or DisplayPort audio, inspect the graphics adapter as well as the sound category. For an integrated laptop codec, start with the laptop maker. USB and Bluetooth speakers may use built-in class support, so a separate download may not exist.
- Record the output device, provider, and current version.
- Check the computer maker's package for an integrated codec.
- Use the peripheral maker only when its exact model is listed.
Treat microphone input as a separate path
Choose the intended microphone in sound settings and in the application. Check the physical mute switch, input level, privacy permission, USB power, cable, and Bluetooth connection. A microphone that works in one application but not another usually needs an application or permission correction.
Laptop microphone processing can be part of the system audio package, while a USB interface may use its own vendor software. Do not assume that replacing speaker output support will repair a microphone that is blocked, muted, or not selected.
Install and test the matching package
Use the signed installer from Windows Update or official support. Audio can stop briefly during installation, and a restart may be required. Do not install generic codec packages from download catalogs or remove every audio endpoint to fix one selected-device problem.
After restarting, test speakers, headphones, microphone input, volume controls, sleep and wake, HDMI output, and the application that exposed the issue. If a graphics update changed HDMI sound, investigate that graphics package and output path rather than repeatedly reinstalling the internal codec.
- Keep another input method available before changing core audio software.
- Roll back only for a clear, repeatable regression.
- A damaged jack, cable, speaker, or microphone needs hardware service.
Recover from a new audio regression
Record the package version and the affected endpoint. Use the supported rollback option for that device or the official computer-maker recovery process. Restore the prior working endpoint and test it before trying a different package.
Common Questions
Do microphones have a separate driver?
Some devices have a vendor package, but many USB and Bluetooth microphones use built-in class support. Check the exact model, endpoint, and privacy permissions first.
Why did an audio update not fix silence?
The selected endpoint, mute state, application permission, cable, pairing, or HDMI path may be wrong. Test those causes before repeating the installation.
