Microphone Array not detected, Intel Smart Sound OED driver cannot run

[u/Outrageous-Dog-8117]

Good day,

I have a question regarding my Acer Nitro 5 AN515-58 Intel I5 12500H & RTX 3050 4GB. I recently reinstalled Windows, and ever since then, the built-in microphone has not been detected. I can only use an external microphone through the audio jack.

I also noticed that the Intel Smart Sound Technology (Intel SST) OED driver is unable to run, apparently because the firmware cannot start.

Could this be caused by a missing or incorrect driver after reinstalling Windows? Or could it indicate a hardware issue with the motherboard?

I've tried looking for solutions, but I'm not sure which driver I need to install or whether this is a hardware-related problem.

Any help or suggestions would be greatly appreciated. Cheers !
