Slackware 15.0+ plasma kde desktop not recognizing motherboard on board audio device

I just built a new PC with a Slackware distribution and cannot get the audio to work. I have another PC that I build last year with the same MB, processor, and RAM, basically the same machine and the audio works on it. I have attached screenshots from the Configure audio devices of the plasma KDE desktop. As can be noticed on the configure audio settings of the working box it shows drop downs for port and profile in the upper right whereas the non working box does not show these. I have tried to find the answer on line, but don't seem to have tripped upon it yet. I have run these commands and still can't seem to find the issue.

These commands listed the same thing on both the working and non working boxes:
