MacBook :: High Frequency Ringing Sound When Both External Monitor & Speakers Are Connected?
Jan 8, 2009
I searched the archives and I can't believe no one has mentioned this yet! This is a huge problem on both my Rev A and my new Rev B. When you connect an external monitor and external speakers using the headphone output, there is a high frequency ringing sound coming out of the speakers. I've managed to live with it by turning the treble to minimum and keeping the volume low enough but at the expense of sound quality. The strange part is, if you disconnect the monitor, the ringing sound stops. The problem only occurs if you have speakers and monitor plugged in at the same time. I've tried this on my Samsung monitor, my SONY TV, and my Panasonic audio receiver. The problem occurs with both Rev A and Rev B while my white MacBook and 2007 MacBook Pro all sound fine.
I hope I'm not double posting. Have any of the other new iMac owners experienced weird frequencies coming from external speakers that are connected to their iMacs?
For example: I have a set of studio monitors that are hooked up to my iMac using a firewire audio interface. Whenever I'm copying data I get an extremely high-pitched frequency coming from my speakers that sounds like my hard drive spinning. Also, whenever I'm scrolling or moving the magic mouse I get a loud buzzing coming from the speakers (especially when scrolling). None of this stuff happened with my previous 20" iMac C2D. I have experienced this issue with all three of the 27" iMacs that I have gone through thus far (due to the yellow tint issue). Does this sound like something I'm just going to have to live with. All of these high pitched frequencies are driving me batty!
I have a 24" aluminum iMac G5. I have never had a problem with sound before, and feel like this problem is isolated to a certain DVD but the DVD works on EVERY other player I own. Everything pretty much plays DVDs, so that's many!
So here's my problem: There's parts of this movie that have very high pitched sounds, like electronic sounds that are just sound effects in the movie. Whenever I get to those parts in this movie (maybe even other movies for all I know, I don't play many) and the sound goes quiet, like the speakers can't handle that high pitched sound.
I feel there must be something I can do about it, right? I just use the regular default DVD player application that pops up when I put a DVD in. I tried playing with that equalizer but nothing changed. Any ideas...?
When I connect to an HD TV using the Mini DisplayPort (via a Monoprice Mini DP-DVI dongle and a Monoprice DVI-HDMI cable) and to a Hi-Fi system using the headphone out, the Hi-Fi speakers emit a loud and persistent high-pitched whine.The whine disappears when I disconnect the Mini DP dongle, and also when I disconnect the audio cable so that the sound is playing through the internal speakers. There's no whine when I connect earphones to the MBA instead of the Hi-Fi. I don't have another external display with which to test the issue, so I'm not sure if this sound exists when the computer's connected to, say, an ACD.I'm surprised that this problem doesn't seem to have been mentioned on this board, but it's well documented on the Apple boards (1, 2, 3, 4). The consensus over there is that it's a fundamental design flaw in the MBA and that the only solution is to get a ground loop isolator. Has anyone here had the problem and been successful in getting it fixed by Apple?
I have just ordered a Macbook Air. I have an external monitor that has speakers seperate. If I use a minidisplay port to hdmi adaptor to connect to the monitor, will the sound be able to be played out of the speakers of the Air? If not, can I connect an audio jack and have it play through the seperate speakers?

I just got my iMac yesterday, and its been awesome, but I have one question. The classic "bong" sound at startup, I know that is the result of a successful POST, but mine didn't do one after the 1st startup. I had speakers plugged in to it when I started up the 2nd time, and no sound. I unplugged the speakers, and I got the sound. Is that normal or do I need to contact Apple? I jut want to make sure nothings wrong with my iMac. I checked the POST results in System Profiler and it said Passed.
Okay, So i have my Unibody Macbook Pro (late 2009) hooked up to external speakers (RCA Home Theater system with a standard audio cable). Everything works fine and there is no buzz or sound except for the music of course until I plug my printer in. I know the obvious solution is to unplug the printer when listening to music but the printer is shared and other people print off of it etc. and I was wondering if anyone knew why this happens.
After upgrading to Lion, there seems to be very little sound coming from my external speakers. Speakers work with other devices but not so much with MacBook Pro. In iTunes, the volumn slider is maxed out with the speaker volumn on the keyboard maxed out too. Used to blast out the house, but not now.
Don't know if it's as a result of the upgrade or not. I did a PRAM reset but still nothing.
Info: Mac OS X (10.7.3), external speakers are harmon/kardon
I've just purchased a new sr macbook pro 2.4 ghz. when i plug the macbook pro to external speakers, the quality is really bad, no bass, just high tones. I allready checked the equalizer in Itunes and I turned the bass all the way up, but the sound was still horrible...
When I connect my macbook pro to a tv (via dvi to video adaptor) The sound of the external speakers goes even worse. The adapter causes like a weird tone in the bass...
New MacBook Air...internal speakers work fine. Have Bose speakers that I just tested on my Dell laptop, so I know they work. When I plug them into the headphone jack I get no sound. Volume is up and mute is not on.
There is no sound coming out of my speakers- internal or external. This problem just recently happened (I didn't get my MacBook Pro with this problem). I have checked and double-checked the sound preferences. Nothing is muted or anything and the correct "device for output" is selected.
where the external speakers i am running through my Focusrite Saffire 6 USB interface have ceased producing any sound at all when linked in to the Macbook Pro . I have plugged them in elsewhere and they are working fine , so that is not the issue .
i had performed the software update on my Macbook pro to get OSX 10.9.3 . I have gone in to sound settings and made certain that both input and output are set to the Saffire interface . A signal is certainly coming through and sound can be recorded , so input is fine . I have also done this in both Garageband and Logic , to no avail . However this issue is effecting ALL sound in the sense that nothing is coming out at all from any source . No sound is coming out headphones when plugged in to the interface.
Thought it might be the interface but this literally happened as soon as i tried using my set up with the new OSX 10.9.3 software installed . Oh and i also get an error message whilst playing a track on garageband : "Error while trying to synchronize audio and midi...Sample rate 42212 recognized , check conflict between garage band and external device". Here's a reminder of gear used :
-Macbook Pro OSX 10.9.3 -Focusrite Saffire 6 USB Interface -Yamaha HS50's
I have a problem with the headphone jack of my macbook. When i plug in some headphones or external speakers, it wont get sound to them, just like the headphone jack isn't there and the sound come out from the macbook speakers. The only ones that seem to work are the ipod original ones, but not if insert them completely, they need to be strategically plug in, like half in and half out, and if i move it a bit more the sound goes back to the speakers again. Does anyone knows what this might be and how to fix it? I can't use the warranty, because the warranty time already passed.
I am trying yo plug my NEC EA231WMi into my MBP via DVI and a DVI to mini display port Adaptor and the computer is not recognizing the monitor. It does nothing when I plug the monitor in.
Im looking to get an imac and some speakers. Im coming from a pc computer with build in speakers in the monitor and they sound horrible, so im guessing the imac wont be much different. So what are some good speakers I could get for 100 bucks?
I just bought a pair of the Rokit 5 external speakers. When I plug them into a Mac Pro (Tower) I get a high-pitched hum from the speakers each time I try to play a sound. So if I go into System Preferences/Audio, and I try to play a sound, the high-pitch is heard as the sound plays, and for a second or two after, then it goes away, and is heard again each time I try to play a sound. Same with when I play something thru iTunes or any of my audio apps.
If do the exact same thing playing from a Macbook, I do not have that problem at all, the sound is nice and clear with no high-pitch sound.
I have the speakers plugged in using 1/4 inch jacks to an external sound card (MBox), and this audio card is plugged USB into the Mac.
Did any of you experienced this ? My WiFi slows down or even stops working when external monitor is connected (via the big connector, don't remember it's name, DMI or something like that). Air Rev A, 1.6.
I have a strange problem with a WiFi slowdown when connected to a TV. Here are the specs of the equipment: 2.2 Ghz white macbook, santa rosa, 4 gb ram, purchased January 2008 Panasonic TV connected via HDMI to DVI cable + Apple Mini DVI to DVI connector USB Western Digital harddrive connected to a 500 GB Time Capsule (1st edition, no dual channels) Snow leopard 10.6.1
Before upgrading to snow leopard, I would frequently use the macbook to provide video to the above mentioned TV streamed from a hard drive connected to an imac (connected to the same time capsule). I moved, and upgraded to snow leopard, and haven't tried this until finished setting up my equipment yesterday. I can stream videos to the macbook from this hard drive fine when nothing is connected. However, the moment I plug in the mini-DVI connector, the WiFi drops to a crawl. This applies not only the to air disk but any data from the network (internet, etc.)
A couple of additional notes: Display is set to mirror. Has nothing to do with clamshell mode because the macbook isn't closed. Nothing to do with location/interference- the effect is instantaneous with plugging and unplugging the cable. The base station is actually closer than in my previous setup and is pretty much 20 feet away in direct line of sight. I connect to another external monitor daily at work (vga, again with apple mini dvi to vga adapter)- no issue whatsoever restart did not help. I canceled all time machine backups over the network to limit that as a factor- no effect.
WITHOUT closing the lid, because i like using the touchpad. i know that you can turn the brightness all the way down, but sometimes windows from the main screen randomly open on the other display. and it also slows down performance. i want to turn off the 13" screen as if the lid was closed. that way, the mac doesn't even see it.
I have a Mac Pro 2x 2.66GHz Dual-Core (4 Cores) Xeon 5150 (Early 2006).The internal speaker chimes when I start up even though I have external speakers connected to the analog output on the back.
Well my unibody macbook display decided to screw up last night, it was working fine last night no problem. Connected to a external monitor. I fell asleep last night with front row left on, obviously it went to sleep and then I woke up and the screen was black. Now the LED lights are working, my external display is also working. The display settings recognize a screen being present (when I click detect displays and gather windows - 2 windows appear). Ive reset PRAM, SMC, reseated the RAM, control+shift+eject (which just made the screen flicker a little after turning it back on) and Im out of ideas. Its out of warranty and about about 18months old.
I have a 13" MBP and just bought a new 23" external monitor connected via mini DVI to HDMI adapter.The monitor is recognized fine, but there is extreme jitter on the screen - basically very annonying and unusable.
my screen cracked on my MacBook and I'm unable to see anything (it's just fuzzy white) so I purchased the VGA adaptor so I can connect to an external monitor. When I plug in the screen is zoomed to close and I can not view the entire screen. I can see one application that I have open, which is iMovie but can not see the top menu or my icons at the bottom. How can I adjust the settings seeing how I can not access the menu bar or anything else for that matter. It also appears to be showing a second screen, maybe not my desktop because the background is different. I'm running on OS X Lion.
I'm trying to finish an end of the year slide show for my kindergartner that I need completed today, I was five minutes away from finalizing then my two year old threw his monster truck at my screen!
I have bought a set of external wireless speakers to listen to iTunes while outside. If I plug my iPod into the wireless transmitter jack they work great. The problem is getting the speakers to work using iTunes on my iMac. If I plug the wireless transmitter jack into the headphones socket of the iMac I get no sound.
I bought a MBA 13" last month and now I'm trying to connect an external monitor through a Mini Display Port-to-HDMI adapter and most of the times the display shows a message "No signal detected"...
I've tried all the possible combinations between the MAC and the Monitor but it would seem a random matter.
Info: MacBook Air (13-inch Mid 2012), Mavericks 10.9.4
After re-arranging my set-up, I suddenly have no sound from my external speakers (JBL Creature II). After the first panic, I figured I would try with my MBP. Odly, they work just fine with that. Then i tried with my headphones from my iPhone - no sound at alle. I?ve resetted PR-RAM (twice), and is now stocked - and pissed.
Is there an easy way to cause a connected external monitor to be "disabled?" E.G. I have an iMac connected to an LCD TV (via VGA, spanned, external at 1360x768). If the TV is plugged in, even if it's off, the computer switches to spanning mode. The consequence of this is that, if my preferred setup is to have the external be main, for instance, I essentially have to unplug it from the iMac whenever I don't want to be using it. Even if the external is the 2ary dsplay, it means that the mouse can go off the edge of the screen on one side, and that two of the hot corners are messed up. Is there any utility that could do something like add a "disable external display" item to preferences or the menu bar?
