Some patch made on FreeBSD

I'm glad I can contribute to my favorite server OS. I received this computer some week ago but the sound is not functional out of the box with the FreeBSD, so I tried many fix and adjustment until it works. Now the computer become multimedia computer for playing music, youtube and all in my living room.

Playing music on the computer is priority to me, as I need to play along the music with my musical instruments, some kind of beneficial activity in my free time.
