Fix upside-down or inverted webcam on Ubuntu linux

I am running Lucid Lynx 64 bit OS version on my Asus i3 K52J Series laptop. Like everyone else, I like using Skype video/chat as well as Cheese camera for taking pictures and videos. Not until then when I had a problem using it.

NOTE: Not advisable to do "export LIBV4LCONTROL_FLAGS=3", LIBV4LCONTROL_FLAGS is for debugging purposes only. - by Hans De Goede(libv4l author and maintainer)

I was so disappointed that my camera display was inverted! I tried reading several blogs and posting comments on Ubuntu forum threads online for days and but none of their solutions helped solved my problem. It could have been easily solved if only there was an option to invert my camera on Video4Linux Device Preference. Sadly, there was not! So, I decided to find a way to flip the camera by looking into export options on gtk-v4l(Video4Linux). 

Fix Asus K52J Sound or Speaker Problem

I just got a new replacement company laptop for my 2 year acer dual core laptop. I now have Asus i3 K52J Series Laptop. Like everyone else using Lucid Lynx on their Asus. I had a problem with my sound and audio device and drivers.

Some of my problems were:
  • Speakers do not mute when headphones are plugged in.
  • HDMI sound out not working.
  • External microphone not working.
Thanks to this Ubuntu Forums Thread where a fix is posted though incomplete in my case. So, I decided to create one of my own and hope to help someone else looking for a solution online. The steps below are the things I did fixing this problem.
