Camera app shows error "0xA00F4244 NoCamerasAreAttached"

problem not solved

Hi, I read your post sounds good.. but I have no idea how to go about reverting to older drivers nor locating the sensors you mention.

I have an All in One HP Pavillion PC.

According to the Device manager my hardware is a HP 2.0MP high definition webcam (manufactured by Microsoft) and a HP IR Camera but the icons are both grayed out. Clicking on properties, I can see the driver details (none like what you mentioned) and I can Update drivers (done multiple times) and uninstall the device but I am unable to roll back the driver, which is what I feel I really need to do!

I even upgraded to windows 11 thinking that the drivers might sort themselves out but no such luck.

Where do you suggest I go from here in order to a) find the drivers you mention and b) downgrade them?

Thanks for your time

Since I use Norton Driver Updater, I was able to determine which drivers were updated since the last time I used my camera for a Zoom meeting. When I realized the camera was not being detected (subject of this thread), I just went back through the history of updates by Norton Driver Updater and found the Camera Sensor driver had been updated. Norton Driver Updater allows reverting to a previous version. That fixed the detection issue, but the camera video wasn't being processed. I then found the AVStream driver had also been updated at the same time as the Camera Sensor driver, so I reverted that driver and all was well.

Prior to these discoveries, I checked with Samsung and all they wanted me to do was take the laptop to a service center or replace it with the latest model for nearly what I spent for the laptop to begin with!

You might check the WIndows Update/Update History/Driver Updates to see when an update occurred that stopped the camera from working. However, if you are not using a tool such as Norton Driver Updater, you will likely have to take your laptop to service center that specializes in your brand of laptop.

Hi Dan,

First, I never understood how you update two drivers on the same device. The Camara Driver and the AVStream driver. What's more, I don't know what the AVStream driver is (my language is Spanish. It's probably a translation problem). On my Lenovo Ideapad with my SunplusIT camera the only thing I see to update is the "Integrated Camera" driver.

Anyway, I managed to find a catalog of Microsoft camera drivers (https://www.catalog.update.microsoft.com/Search.aspx?q=windows%2010%20camera%20driver) and there are dozens of drivers available for each year. Since I no longer remember when exactly my camera stopped working, I have installed random drivers from different years ago (2017, 2018), but have not had success yet.

I have also tried installing software like "DriverIdentifier", although it confirms that my driver is outdated, it updates it, but it does not solve the problem.
