Hello,

I have the very same issue. I am a newbie on freebsd. I installed iFreeBSD
fujitsu 11.2-RELEASE with kde5 to my fujitsu 920 minipc. I have currently no
sound. Since I am trying to configure this machine as my primary desktop
machine this is a show stopper for me. Is there a way to circumvent this
issue..
