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. > > On 13/04/2012, at 9:50 AM, Tim Law wrote: > >> Hi, >> >> I have an intel Mac Mini late 2009 running under Lion. >> >> For the last month or so I have not been able to run the external speakers >> that I plug into the headphone socket on the Mac Mini. i.e. no sound comes >> out. >> >> I can use a set of headphones that are connected via a USB port. >> >> I have also noticed that the internal speaker does not work. >> >> Having said that, the internal speaker did work last week, but not this >> week.
