Windows 10: My left ctrl key keeps muting audio

Hello. I own a Windows 10 Home computer and everytime I press left ctrl my audio is muted, this is really bad for gaming, which I do often.I have checked ease of access, audio, and time and language, but it didn't work.I have also re-installed my keyboard drivers, as well as uninstalling it. But it also didn't work.How can I fix this?

:)

 

Pressing left ctrl mutes my audio and when pressing my left shift button it types this character: |

Hi thanks for helping me, I just did this, and sadly it still mutes my audio when I press left ctrl. Is there another way to fix this problem?

 

Windows 10 | Left Shift reduces volume, Right Shift toggle mute and Left Ctrl toggle airplane mode

I have a new laptop HP Pavilion 15, with Windows 10 Home, and the keyboard (a standard QWERTY) if isn't working properly:

• When I press the "Left Ctrl" key it's enable/disable Airplaine Mode and opens the Outlook app.
• When I press the "Left Shitt" key it's reduces the volume.
• When I press the "Right Shift"key it's enable/disable the Mute of the volume.

I already tried:

1. Installing updates from Windows Update Center.
2. Installing all driver updates using HP Assistant.
3. Tried another keyboard layouts.

Is there anything I can do to check if it's either a software problem or a hardware problem?
