HP Recommended
Product: HP EliteBook 840 G6 Notebook PC
Operating System: Microsoft Windows 10 (64-bit)

After Windows Updating I found that there is driver of Smart Sound Technology (Intel SST) OED missing and Sound is not working. INTELAUDIO\DSP_CTLR_DEV_9DC8&VEN_8086&DEV_0222&SUBSYS_8549103C&REV_0011
I rolled back the driver by rolling back the driver for the Intel Smart Sound Technology (Intel SST) Audio Controller for previously installed version,  but it was not able to resolve the problem.

in the device manager was written: DSP_CTLR_DEV_9DC8&VEN_8086&DEV_0222&SUBSYS_8549103C&REV_0011\4&67fd074&0&0800 had a problem starting. No speakers found, no microphones found.

The description for Event ID 0 from source "Intc OED" cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer.

The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly.

 

What have to I do now? If anyone knows about this one, please share your knowledge.
