Intel Smart Sound Technology issues

Posted by JustKenjy@reddit | sysadmin | View on Reddit | 7 comments

Hey everybody.

I have been having an issues across multiple Dell laptops (mostly 3540/3550 dell laptops).

On some PCs the camera & mic stop working. Others its just the mic.

I do not have the audio controller, only the OED, BUS and Detection verification for Intel Smart Sound Technology.

I've tried disabling drivers, installing new drivers, updating BIOS and absolutely nothing is working.

In the meantime I have installed older drivers but the issue seems to stick.

Has there been a confirmed fix for this or any other suggestions

Thanks!

What are the laptops connected to?

We had some complete freezes when connecting Bose Video Bars.

Also: installation sequence matters with these drivers. Completely uninstall and reboot before attempting to install an older version.

Laptops aren't connected to anything. Just standalone, so its the internal microphone being used. When testing the microphone you can hear a pop / buzzing sound. I'll try with removing the drivers, but if I am not mistaken it just reinstalls after a reboot.

Sound enhancement issues could come from Dell Optimizer as well.

What’s the noise like if you use the audio jack? (Not USB or BT headset)

Nothing connected at all, and its not output noise, its input noise.

Try a headset via audio jack. If there’s no distortion you know it’s probably cabling or hardware.

Also: make sure your audio driver is newer than 2024. A similar sounding problem was fixed way back when.

Via headset it also does not seem to work if I am not mistaken.

This is a known issue for Dell devices, just all the fixes I tried aren't working. It is definitly connected with the Intel Smart Sound Technology drivers because I have the same issue across 2 laptops now.
