| 1459125 | 2019-03-17 23:11:00 | Had to wait till today to play that, the headphones wouldn't go loud enough, so onto the Workshop PC crank up the speakers :) Defiantly static alright. Doing a bit of looking around it appears to be a regular problem with some MAC's and iTunes. Some say its the equaliser or QuickTime causing the problem. Whether the no functioning headphones have anything to do with it I don't know, BUT try this -- Install some other media player, theres plenty, ( just a couple) VLC, Clementine. Once installed try playing something see if you still get the static - if not - its something to do with iTunes. |

| 1459127 | 2019-03-18 18:00:00 | Morning guys, I sincerely appreciate your help! So I first did the SMC reset and while restart no static noise appeared when you hear the chimes when the Mac first starts up. I installed VLC and played a random song and although the static sounds now sounds more faint it still remains there. I then opened iTunes, same static sound, same level of static noise.. It also appears in browsing, when there is a commercial thats playing or a sound file. It starts as the same time the notification or commercial does, then turns off 20 sec after...am starting to think it is the power board and socket? I should try that tonight when I get home to relocate the Mac and see if it still continues in another socket, power board or room?? Do we get these outlet checkers in New Zealand? | mark1978 (13845) | ||

Try another power outlet in another room. You did say it does this on battery though ? Its unlikely to be that, both the MAC's power supply & the motherboard will have plenty of filtering Since it doesnt have this issue through Bluetooth , it could be an issue with the audio circuit (the built in amp that powers the speakers). A complete wipe/reset of the OS might be the next step , just to confirm its not a software/driver issue . Or just use BT speakers . |

| 1459129 | 2019-03-19 05:10:00 | Hi 1101, its an old Mid 2011 iMac desktop, so no battery. I have put the iMac in the kitchen and plugged it in there, no static noise through the apple chime but as soon as I open iTunes, a website or a notification comes on so does the static noise, however it seems more faded. the intensity of the noise seems to vary. I believe it might be an issue on the logic board. I attempted to log out and log into a guest account to see if its a software issue however it does the same thing. frustrating! If I knew where on the logic board the problem is located I would take it apart and inspect it. | mark1978 (13845) | ||
| 1459130 | 2019-03-21 07:35:00 | I took the iMac apart tonight, cleaned it out, put back together, to no avail. Thanks for everyone's support. :) | mark1978 (13845) | ||
