Re: Losing sound output on Mac Mini
Daniel is truly multi threading on 64 bit - I'd not done a PRAM reset, but have done a SMC reset Given he is obviously paying attention, perhaps that light really was orange! :-) bit later I've now done a PRAM reset. No difference And tried the iPhone headphones. Still no internal speaker or headphone noise. In the System Preferences Sound all that is displayed is my USB headset. No 'Inbuilt speaker', nor 'Headphones'. I think I really need to buy a new computer. I mean, a Mac without it's chime is .. ?

Re: Losing sound output on Mac Mini
Disconnect your USB headset then try inserting your headphones. If still no go... Try starting up in Safe Mode. To start up into Safe Mode (to Safe Boot), do this: Be sure your Mac is shut down. Press the power button. Immediately after you hear the startup tone, hold the Shift key. The Shift key should be held as soon as possible after the startup tone, but not before the tone. Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).

Re: Losing sound output on Mac Mini
Hi Tim, If none of the suggestions have corrected the problem, run the Apple Hardware Test (AHT) Hold down the D key while starting up. If you get the Hardware Test screen, select the extended test. If you don't, the Hardware Test is not resident on your hard drive, and you'll need to start up from one of the DVDs that were originally shipped with your computer -- whichever one says on its label (in small print) that it contains the Apple Hardware Test. Insert the disc and again, start up while holding down the D key and select the 'Extended Test'. It can take awhile, let it complete. Post any errors you receive.

Re: Losing sound output on Mac Mini
There is no light, green or red, shining from the headphones port. AHT run on extended - says there are no problems. Time for Ray's solution me thinks. Tim On 13/04/2012, at 11:24 AM, cm wrote: Hi Rob, Not a bad though, Rob. You are thinking of so-called Toslink or digital audio. It operates by sending green light pulses down an optical fibre. So if the light is on the Mac mini is in digital audio mode. When digital audio is on standard 3.5 mm headphones / speakers will not operate. C On 13/04/2012, at 11:21 , Rob Phillips wrote: I'm no expert on this, but the audio out can provide both analog and digital output, and there's a little microswitch hidden inside the socket. If that switch gets accidentally changed, audio fails. There is a little light in there which indicates one or the other modes, but I'm not sure which is which. Hope this gives you something to look into. However, given that the internal speakers also don't work, it could be hardware.

Re: Losing sound output on Mac Mini
Ray Forma gets the Gold Logie tonight! I opened up the Mac Mini and found a ball of dust across one of the ends of the ribbon cable ends. The cable was connecting fine, but I suspect the dust was creating just enough of a nuisance to short something out.. On start up after reassembly the familiar chime had returned. In the system preferences I can now choose Headphones if some are connected, or my USB headset. And when I remove the Line out for the speakers, the System Preferences then offers me Internal Speakers - somewhat of a misnomer because there is only one. I know dat, cos I bin inside :-) Thanks Ray! And Ronni, Daniel, Rob and Carlo for your input too. And whilst I was there, I found an antenna cable had been pinched on reassembly - no doubt after a motherboard replacement at a local service centre :-( And with all of this success, there is no red or green glow coming out of either the line in or line out audio plugs. Must have been a model change, mine is late 2009. I think I'll do a restart much more frequently now, just to hear the chime. :-) Tim On 13/04/2012, at 3:34 PM, Ray Forma wrote: Tim, further to my email earlier today; a sign that the ribbon cable is probably suffering is, whenever the Mini is on, there is NOT a red glow in the sound-out socket of the Mini.

Re: Losing sound output on Mac Mini
I'm no expert on this, but the audio out can provide both analog and digital output, and there's a little microswitch hidden inside the socket. If that switch gets accidentally changed, audio fails. There is a little light in there which indicates one or the other modes, but I'm not sure which is which. Hope this gives you something to look into. However, given that the internal speakers also don't work, it could be hardware. Rob On 13/04/12 10:53 AM, cm wrote: Hi Tim, You could be experiencing a hardware failure.

Re: Losing sound output on Mac Mini
Hi Rob, Not a bad though, Rob. You are thinking of so-called Toslink or digital audio. It operates by sending green light pulses down an optical fibre. So if the light is on the Mac mini is in digital audio mode. When digital audio is on standard 3.5 mm headphones / speakers will not operate.

Re: Losing sound output on Mac Mini
Tim, I recently opened a Mac Mini of mine: Model Name: Mac mini Model Identifier: Macmini1,1 Processor Name: Intel Core Duo Processor Speed: 1.66 GHz to install bigger memory and bigger HD. When I reassembled my Mini the internal speaker was silent, as was the sound output port, both with cable and toslink. Panic, as the Mini, with EyeTV is our long-serving, and excellent TV source! Reopened the box and noticed that the ribbon cable between the 'lid' and the main part, or 'body' of the Mini was obviously involved with sound as all of the sound circuits and sockets were on the 'lid' part of the Mini. I also noticed that that ribbon was loose at its 'body' end connection. Then noticed that the tiny plastic ears of the fitting at the end of the ribbon had broken off, resulting in it no longer securely clicking into the socket on the 'body'. With subsequent handling the remains of the plastic bit fell off the end of the ribbon! Carefully superglued the plastic bit back onto the ribbon. Then stuck down the ribbon with some electrical tape to hold the ribbon snugly into its socket. Reassembled the Mini, being very kind to the ribbon cable while doing so. Sound is back in all its forms! Your model is probably similar, and may have the same problem. If you want to inspect your Mini, look at the how-to video at http://eshop.macsales.com/installvideos/mac_mini_2009_mem_l/ On 13/04/2012, at 9:50 AM, Tim Law wrote: Hi, I have an intel Mac Mini late 2009 running under Lion.
