Whenever I tried to call through Skype I heard the sound irregularly

Hi Techvy,
I have a problem with my HP laptop, my webcam and microphone stopped working after I updated my Skype program. It can work with no problem before, now when I try to make a call using Skype, my microphone echoing irregular sound. I also tried to check the problem by calling the Skype echo, but there is nothing wrong.
Because of that, I again check the Skype webcam setting and I get results as in the picture below

Beside the picture above, I try to access the CyberLinkYouCam program and get error message too,
