Question

SST OED error unable to use audio devices

her 0

Operating System: Microsoft Windows 11 A few days ago after booting my laptop, my laptop stopped recognizing or detecting its own speakers and plugging a headphone through the headphone jack also goes undetected. Only way to play audio currently is through Bluetooth. In device manager I have an error related to intel SST OED, I have tried uninstalling the driver and letting windows reinstall it after restart, used SDI to install it, tried installing it through fortect and it still displays: This device cannot start. (Code 10) FW did not sent FW Ready notification.

Hi ,

Search for msinfo32.exe in the search bar, take a screenshot, and post it here so we can see the correct laptop model or desktop configuration.

Can you access Device Manager, take a screenshot, and post it here?

Thanks.

Hi,

I recommend using DDU.

https://www.wagnardsoft.com/forums/viewtopic.php?t=5582

Note: DDU is a third-party application used to completely uninstall and reinstall the audio driver.

After downloading, extract DDU to a folder.

Run the Display Driver Uninstaller application, select the "Device Type" tab, and choose "Audio." Then, select "Realtek" to uninstall the Realtek driver.

Click the first option, "Clean and restart," and wait for the process to complete.

After running DDU, install the driver:

Select Windows and Windows 10.

Chipset Driver (6)

Intel Chipset Installation Utility

Intel Management Engine Driver

Intel Serial IO Driver

Intel Dynamic Tuning Driver

Intel Dynamic Platform and Thermal Framework Driver

Intel Trusted Execution Technology (TXT) Driver

Audio Driver

Realtek High-Definition (HD) Audio Driver

Open the Command Prompt (as administrator) and run the following commands: sfc /scannow and dism /online /cleanup-image /restorehealth. Wait for the process to complete and restart the computer.
