The system audio device of my Mac Mini 2012 isn’t available, neither in System Preferences nor in the System Report.
I bought this Mac Mini only recently second hand, replaced the second hard drive with an SSD, and made a clean install install of OS X 10.11. I hardly used the computer before and therefore can’t say for sure if the system audio device had been working before.
Any clues what could be the cause, and how to fix it?
Audio output over DisplayPort/HDMI works. SMC and PRAM reset did not solve this issue.

@danj Thanks again for your help. I had another look at the logic board but found no suspicious traces near the audio chip - at least no difference to other areas. Maybe you can see something?

I think I’ll leave it as it is now before I cause any ''serious'' damage to the Mac’s innards - unless of course you or someone else have further suggestions.
