Windows 10: My sound device isn't being detected.

I just turned my PC on, and suddenly it doesn't detect my sound device. I've tested it on other appliances and computers just to be safe, and it's working as intended, but my PC isn't detecting it. Some help, please?

:)

 

Printer isn´t working after latest update.

After the latest update from Windows, my Canon Pixma ip6600 printer isnt working. In Device Manager it shows up as working properly but when I go to print it isn´t listed as an option in any programs. Troubleshoot suggests it´s a USB 2 printer on a USB
3 port and that that´s the problem but that cant be since it worked fine before the update. I´ve tried to uninstall and plug it back in but that doesn´t work either.

Hi Jan,

Do not worry we will help you with this issue. We appreciate your interest in resolving the issue.

The most common cause of this bug check is when a file system or driver has a mismatched sequence of calls to disable and re-enable APCs

Try few of the troubleshooting steps below and check if it helps.

Step 1: If the device is not detected on your computer try to run
Hardware and Devices troubleshooter as it checks for common problems and makes sure that any new device or hardware connected to your PC is installed correctly.

• Press Windows key from the keyboard, type
  Troubleshooting and select it.
• Click on view all option on the upper left corner of
  Troubleshooting window.
• Select the Hardware and Device
  options from the list.
• Click Next to run the
  Hardware and Device Troubleshooter.

Step 2: Fix the driver issues.

Press Windows + X keys from the keyboard, click on
Device Manager and on Scan for hardware changes.

Step 3: Rollback the driver.

• Press Windows + X keys from the keyboard, click on
  Device Manager.
• If you are able to find the Audio drivers, expand it.
• Right click on driver, select Properties.
• Go to Drivers tab, click on Roll Back driver.
