Alienware M17xR4 Speakers not working, and Alienware AlienFX Button on Keyboard not working.

TITLE IS MAIN DESCRIPTION. 

I bought this laptop off a pawnshop about half a year ago. Everything was in working condition. The speakers were working, and the AlienFX button on the top right was working. About 2 weeks after buying the computer, the button on the top right for the AlienFX shortcut stopped working. I now have to click on the bottom right icon on the screen to access that function, and that button has become completely useless. About 4 months of using the computer, I updated to Windows 10, and around that time my speakers stopped working as well. I now have to connect Bluetooth speakers, or any headphones just to listen to anything. I am connected to the same speaker option that I was before the Windows 10 update. Windows says the speaker is transmitting sound, but the physical speaker isn't doing that.

Troubleshooting attempts done:

• Tried updating ALL see-able items to fix both problems. This includes the graphics card updates and windows updates.
• Tried re-installing the speaker driver, updating it to the newest one(apparently that is the newest one), and enabling the older Microsoft windows sound driver version as well.
• Tried troubleshooting the speaker, Windows said there was no problem.

Is there a driver I can reinstall to fix the top right button for the AlienFX to work again? And what else can I do about my speakers? Thank you for helping!

LOOKING FOR ANY METHOD EXCEPT HAVING TO TAKE THIS THING APART. I HAVE NOT DAMAGED THE COMPUTER IN ANY PHYSICAL WAY, AND I HOPE IT WILL NOT HAVE TO COME TO ME TAKING A  SCREWDRIVER TO IT. I AM UNFORTUNATELY NOT A TECHNICIAN, AND I CAN MIX THINGS UP VERY EASILY.

Sorry if this was confusing in any way, but I hope this problem can be fixed. Thank you!
