Hi all
I've been having an incredibly frustrating issue with my Latitude E7440. I believe that ever since I've upgraded to Windows 10, I have had issues with my Webcam and my microphone. From reading around the forums, I'm under the impression that it may be a motherboard/driver issue. However, I have on numerous occasions tried to install/reinstall drivers for both in order to fix the problem.
Issues:
Webcam:
Microsoft Camera App says it can't find my camera. The error code is 0xA00F4244(0xC00DABE0)
The webcam no longer appears in Device Manager, there is no imagine devices and as far as I can tell it is not anywhere in device manager at all. In other words, it's not being detected. I have attempted to manually try and install a new camera via control panel, but there is no option to install a webcam. I understand there are no separate Dell or other drivers for the webcam of the E7440 and they were originally microsoft drivers?
Microphone:
I have tried to uninstall/reinstall Realtek audio manager/realtek HD audio manager drivers numerous times and the microphone is not being detected. This used to work fine, but now it's just not appearing at all. In other words, it is not being recognised. I've tried all the tricks on the forums, in terms of "showing disabled/disconnected devices". My issue is nothing like that.
The problem is that when I open the sound devices, the internal/built-in microphone for my laptop is not being recognised. This used to work fine, and I suspect it's a motherboard issue. The only thing shown under Recording devices is "Jack Mic" (not plugged in) and "Stereo Mix". I'm able to record voice if I use an external microphone in the 3.5mm jack, but the internal microphone is no longer recognised (does not show up anywhere).
Under device manager "Sound, video and game controllers" only shows "Realtek Audio" and under "Audio inputs and outputs" device manager only shows "Speakers / Headphones (Realtek Audio)". I just don't understand where the microphone has gone. It's very frustrating.
I've attached a dump from Speccy with my system specifications. This is incredibly frustrating. I would be happy to reinstall an earlier version of windows if that is possible. I just really want the webcam/microphone functionality of my laptop back.
Thank you for your help.
