Help w/ internal speaker

Hello,

I am having uses with finagling my audio drivers/settings to specify to output from the internal speaker instead of a plugged in headphone. There is actually something permanently affixed to the contacts of my headphone jack so it perpetually things there is something plugged in. I know the internal speaker works because I was able to switch to it before my "clean" reset and I also double checked w/ the boot diagnostic. 

My previous solution was to ditch the Realtek HD Audio driver and the native HD audio driver that I was on allowed me to pick either the built-in speaker or the headphones but I can't seem to get that to work anymore. 

Any help would be appreciated!
