Hi everyone, I am facing a frustrating audio issue on my ASUS Zenbook 14 OLED (UX3405MA) running Windows 11 64-bit. The internal speakers are completely silent, while Bluetooth audio via my headset works perfectly fine. This issue always triggers specifically after watching Netflix, followed by a Windows Update. The first time this happened last year, I managed to fix it by reinstalling the audio drivers from the ASUS website (https://www.asus.com/uk/laptops/for-home/zenbook/asus-zenbook-14-oled-ux3405/helpdesk_download/?model2Name=UX3405MA). However, after the most recent Windows Update, the sound disappeared completely, and none of the previous methods worked. When I run playback Realtek Audio, it results "Failed to play test tone."
I have already exhausted all standard troubleshooting steps, bios, uninstall Intel(R) Smart Sound Technology EOD, but it did not help.
Any advanced technical help would be highly appreciated. Thank you!

2026-06-04T22:18:13.19+00:00 Hii,
I recommend you use DDU to remove the sound drivers and reinstall the chipset and sound drivers.
You can use DDU: https://www.wagnardsoft.com/forums/viewtopic.php?t=5582
Note: DDU is a third-party application to completely delete and reinstall the Sound driver.
- After downloading, extract ddu to a folder.
- Run the driver screen uninstaller.exe application, select Model tab, put Audio. After uninstalling the Sound Driver, uninstall it for Realtek.
- Click on the First option clean and reboot and wait for the process to finish.
- After running DDU and install driver : https://www.asus.com/uk/laptops/for-home/zenbook/asus-zenbook-14-oled-ux3405/helpdesk_download/?model2Name=UX3405MA

2026-06-14T18:28:19.5066667+00:00 Hi Ivan, it's me again. I really need your help.
Unfortunately, I forgot to pause my Windows Update, and after it updated automatically, the audio on my ASUS laptop disappeared yet again.
I already tried using the DDU method and reinstalled all drivers in the correct order like before, but this time it didn't work at all, the sound is still completely gone. To make things worse, now my camera is also broken and not working.
