Late 2014 Mini doesn’t offer internal speakers or headphones as options in System Preferences for sound output (used to be available). Only options are Airplay ones. In Logic Pro Preferences, the Audio output selectIon is greyed out, even though Core Audio is checked, and when I click Apply, a pop-up says “Selected Driver not found”. I reinstalled Mojave, but nothing changed.
Mac mini, macOS 10.14

I did try that, thanks for the fast response. Unfortunately, assuming I did the reset properly, it didn’t fix it. HOWEVER - here’s interesting . . . If I boot from an external USB drive running Sierra, instead of Mojave on the Mini, I still don’t get the internal speakers or headphones option, BUT, since the Mini’s display is actually a hidef TV with HDMI, the sound preferences pane does offer the HDMI option, Logic sees it too, and the Mini is outputting sound. It’s not an ideal solution, Sierra is not Mohave, spinning umbrellas everywhere, but the fact remains that Sierra on a USB drive offers the HDMI audio, whereas Mohave on the internal drive does not. Fascinating.
Before starting any further, suggest a full TimeMachine Backup and also a Full Bootable Clone or 2 to external SSD / HD of existing SSD / HD.
Boot in Recovery Mode ( cold boot and hold Command + R immediately) Once in Recovery, choose to Re-Install Mojave over the top of existing installation ( In Place Installation). This will not delete anything and MAY put things right.
Thanks for responding. I did re-install Mojave over the existing installation, like you suggested, but no luck. I still don’t understand why I get different sound options when booting Sierra from USB, vs Mojave from the internal drive. Cheers.
This may sound ( pun not intended ) too simple but try plugging in a pair of headphones into socket. Do you get sound in headphones? If yes, have a look at system preferences and see if things are correct once again.
Have a MM 2011 had connected via HMDI to 27 inch Monitor or sometimes to also via HDMI to 32 HD TV. Each time at startup, can hear internal speaker only until loading macOS HS and then sound is passed to Monitor / TV
No luck. My next option is to clone a MacBook Pro Mojave 1Tb, which works fine, to the 1Tb Mac Mini, so everything will be identical in terms of software. Using SuperDuper for that. If that doesn’t work it has to be a hardware issue and I’ll look at repair options.
Thanks again for your help, very impressive support and responsiveness.
Final thought, have the unit been opened and parts replaced? Maybe a cable has not been seated properly affecting sound from internal speakers.
Have a look at iFixit discussion on their boards over here https://www.ifixit.com/Answers/View/14224/No+Sound+from+Mac+Mini!
I'm declaring victory! The cloning from my MacBook Pro was successful. Even though the Mini can't see the internal speakers or headphone jack, it doesn't matter (to me). All I want it for is to run Logic, and now, unlike before, Logic can see the Roland RD2000 keyboard as its input device. Now that that's done, I just told Logic that the RD2000 was also the output device. That connects to the amp, so I have everything I need the Mini for - running Logic and getting sound out. It's still a faulty Mini, but sufficient for me.
Again, many thanks for your interest and your support.
Do keep us updated and good luck
No Mac Mini sound - missing drivers?
