I just upgraded from 10.6.3 to .4 and now my mini won't play sound. I have tried all the usual suspects by checking into Sound Preferences, opened and checked the Audio Midi Setup info, repaired permissions (both before and after upgrading to .4), but have not tried going backwards via Time Machine. Is there a separate sound board on the Mini? I have what started out as a Core Solo mini, then upgraded the processor to a Core2Duo (1.83) about a year ago (work done by a great local Apple Reseller, it was way too hairy to work underneath the logic board) and have had no problems until today.

Intel Mini 1.83 Core 2 Duo, Mac OS X (10.6.4)

    Have you tried to reset the PRAM?

    Hold down the command/option/P/R keys on the keyboard after you restart and let the machine bong a couple of times then release the keys.

    Hi Joe, thanks for the reply. I tried that and it didn't work. It was interesting however because it seemed to open terminal as a long scroll of items in black and white appeared on the screen

    I've had the problem happen to me again. Has happened prior to recent updates. Fixed by randomly adjusting output volume in System Preferences/Sound whilst also playing around with multiple speaker seatings in iTunes. Tried reseting PRAM first as Joe suggested but likewise no dice. Good luck.

    I've just had this symptom after upgrading to 10.6.4

    No luck with fixing either, I've tried all the obvious...

    Have your tried resetting the SMC?

    This is for Intel machines only.

    Here is the Apple info:

    Resetting the SMC for Mac Pro, Intel-based iMac, Intel-based Mac mini, or Intel-based Xserve

    Shut down the computer.
    Unplug the computer's power cord.
    Press and hold the power button for 5 seconds.
    Release the power button.
    Attach the computers power cable.
    Press the power button to turn on the computer.

    It might be worth a try and doesn't take very long.

    Hello. If I find out anything I will let you know. One reader suggested resetting the SMC Power Mgmt settings by shutting down, unplugging the power cord and pushing the power button for five seconds. Unfortunately I had no luck with this suggestion.

    Good luck in the World Cup!

    Hi Joe! Thanks for the suggestion but alas, no luck with this idea. If I get it fixed I will let you know.

    This happened on my mac mini too. Sound is gone after software update. Tried all the usual stuff. Sound output on multiple speakers in itunes works fine, just not on computer speakers.

    Have there been any developments on this issue? I have a similar problem (cannot select internal speakers) on my Mac Mini; and have reported the problem to Apple a few days ago. No response as yet - is that typical?

    I had this problem and it turned out to be that the cable on the audio card had cracked and was no longer making a true connection. Ordered a new Apple audio board, part no. 922-7316. This is the part inside that has the wide gold cable that must be disconnected when upgrading parts, and so is prone to cracking if a number of installations are performed. It is considered to be a service only item, but is, in fact, not a challenge to install, not even for me- an old lady with no real computer service skills. I bought one, used, from Gainsaver for under $25, once shipping costs were applied (actual cost was $18.99). The cost of a brand new one is in the $50 range.

    Thanks for the tip and citation to the Gainsaver site. I will give this a try.

    Hi, I do have the same problem. After Snow Leopard 10.6.3 to 10.6.4 update no sound. No startup chime, no audio in- or output devices, no nothing. Seems to be a driver problem as I didn't move my mini. Will no try to re-install SL from DVD and then go to 10.6.3 or install the Combo update

    Did any of you have the same problem and do you know a working solution?
    I use the mini as media center, so no sound is really bad ;-(

    Hello ArtfulDodger.

    I saw your post about replacing the Mac mini audio board due to a cracked cable from repeated installs. I have the same problem. I installed a new hard drive in my mini but once I reconnected the gold ribbon cable of course there is no sound. Where/how did you find the part number for the audio board for your model mini?

    I don't see an obvious way to remove the audio board - did you figure that out by yourself or do you know of a location with information on the removal of the old board and installation of the new one? Thanks!
