Realtek offers universal HD Audio drivers (realtek.com/download). However, these may cause pop/click issues on Avita laptops because they lack custom CODEC initialization. Only use this if the official driver is unavailable.
Step-by-step:
Expand “Sound, video and game controllers.”
Note the listed device name(s). Common entries:
If the device shows a yellow triangle or is listed under “Other devices,” right-click → Properties → Details tab → select “Hardware Ids.” Copy the VEN_ and DEV_ values (e.g., VEN_10EC&DEV_0296 for some Realtek parts).
Optional: run System Information (msinfo32) → Components → Sound Device for additional details.
Restart and press F2 or Del to enter BIOS. Look under Advanced → Onboard Audio → Ensure it’s Enabled. Some users accidentally disable it.
You installed the driver, but still no sound. Don’t panic. Try these proven fixes:
Cause: HDMI audio is routed via Intel GPU, not Realtek.
Fix: Reinstall Intel Graphics Driver (DCH) and ensure “Intel Display Audio” is enabled in Device Manager.
Reboot:
$$sudo reboot$$
Check Sound: After rebooting, check if the sound is working. If not, you might need to specifically look for your sound card and manually configure it.
This is the primary method for Avita laptops.
First, you need to identify the sound device or chipset used in your Avita NE14A2. This information can usually be found in the device manager on Windows or through the system information.
