Mac Mini Sound Card.

If you use the Accounts System Preferences to create a new user, then log out and log in as the new user, does the new user have the same problem? If so, then there may be a system-wide problem. If not, then your original user has a preference problem or software issue to troubleshoot. Let us know what you find out from this step and we can try to help from there.

I would still suggest you create a whole new user. This one will have brand-new preferences. It's possible, however unlikely, that both the users on your Mac mini have encountered the same problem. One thing you can try is to reset the PRAM. This will reset the system volume. Restart your Mac mini and hold down on the Apple-option/alt-p-r keys all at the same time. Wait until you've heard the startup chime for the third time (if you can hear them at all) and then let go of the keys. If that doesn't help and/or a brand-new user has the same trouble, then you may need to make an "Archive & Install" of Mac OS X to get all the correct system files back in place.

ok, check this out!!, Go to Itunes - preferences - advanced and turn "look for remote speakers connected with itunes" OFF, I mean without tilt.
That was the problem. Now built in works!!!

Hi its me again (under a different ID) . The solution didn't work after all. It worked until a reboot, and now even though the "Search for external speakers" is unchecked, its still the same.

Since then I've ZERO'd the drive, and re-installed, and STILL have problems with the Audio IN. The Audio out seems to work fine right now.

Sounds like lots of people are having problems... could it be a buggy sound card issue in the Mini's?

Well just for the record Mini's only use a chip for sound not a card. but what happens if you stick headphones in or a microphone? Does it show up unselectable under system preferences or even show up at all?

Last week I bought 11 (eleven) Intel Single Core Mac mini's of which 3 (three) have the sound card problem. In the system profile no soundcard is seen!
Is Apple downgrading??

Yes I returned them today to the Apple reseller. They accepted them as DOA, but the technician said they had to wait for Apple to respond. Perhaps next week I can get 3 new machines. Normally they should swap the devices immediately, 'cause I didn't buy them from Apple but from the reseller. But a week is OK with me.

Update after bringing my three out of eleven DOA-mini's to the Apple reseller: there was a problem with the flatcable being loose on all three machines. According to the reseller that had something to do with the way memory chips are added to the mini. When the technician is not accurate enough the flatcable is getting loose and the mini doesn't 'see' the audio part. Now they are fixed and I will collect them this week.

i have the same problem have u been able to fix it?
