External speakers affect display??

Has anyone noticed that putting an external speaker next to your display for a long time can do anything bad to it.. I could be dreaming but the other day as my display was going to screen saver, it briefly went black and I thought that I saw some very very faint white spots in one of the corners of the display. I can't see anything when all the colors are up, and I'm not really sure if there is a whole lot to see when the display goes black, but I was just wondering if anybody has had that experience or knows if speakers can ruin a display?
Thanks

It really depends on if the speaker has enough shielding. Typically speakers that are designed specifically for use with a computer will be fine. Else some strange things can happen, but normally it's that you get a strange rainbow affect on the screen. Have you tried moving the speakers away and seeing if that solves the problem.

External speakers are no longer working, why?

Ive been Apple Airplay and now my external speakers no longer work on my imac, it is something to do with Airplay or is there something that I need to fix or reinstall? Look forward to hearing from you. TIA

Hi,
There are no external speakers in Sound Preferences/ Output, only internal speakers, or if you plug something into the output port, Headphones, or a sound interface device. Hold down the Option key and click on the sound icon in the top menu bar on your display and you will see the options for output and input.
Have you got an audio system plugged into the output port? If it is not working, check your cables.

Problems with sound from external speakers after iOS 5.0.1 update

Have others experienced problems with external speakers on the Iphone 4 after iOS 5.0.1 update? My phone no longer rings, sounds when i receive a text message, sounds alarm, etc. Vibrate works fine and when i plug in headphones I can hear music through the headphones. Any fixes for this?

Hi Guys,
I have post eariler on another forum and I have the same problem, I have tried all the things listed here and nothing was perminant in fixing this painful iphone hating problem.... and failed. You probably have the problem when you use youtube or your music external speaker that there is no volume bar and no sound.   I have had the same problem But I need to happily say that I now have the fix!!!! This worked for me and I fixed it by myself so you don't need to go to apple or service centre or anything.
Ok I like so many of you here truly believed this was as IO5 issue as it only dropped the sound on the speakers once that IO5 update came along. I tried a bunch of reset, reboots, home clicks, lock and unlocks, to fix this and all failed. some worked for an hour but then failed. hours of my life that I will never get back.   but since I have learnt this is not a IO5 problem but a hardware issue! ... and in paticualar is has to do with your bottom connection. Your phone is thinking it is docked all the time.
To fix the no sound problem what you need is...
1. a torch
2. a tooth brush
3. methalated spirits
4. a butter knife
Step 1.
get your torch and shine it down the bottom connection plate to see what kind of dust, sand, hair or anything you have stuck in there.   all that need to be removed! everything! it might look clean but still thats ok go to step 2.
step 2.
Turn on your music app and put the speakers on! If your phone is like mine it should not work. you most probably don't even have the volume display to turn it on but its ok, just do it! and it should still play with no sound.   its important you try and run the speakers as this will show you that it is a hardware problem.
step 3.
Dip your tooth brush into some methated sprits.   then at your sink tap the exess metho out of your brush as you just want the brushes to be slightly damp, not soaking wet and then scrub the bottom connetiors on your iphone. work the brush back and forward in a way that scoops the dirt out of the phone, not just pushing it side to side.
(As you bushing you should notice the volume bar come back on or off as you scub.   This happened to me and that is how I realised I was on the right track to fixing this problem as I was doing something external that was actually controling when the volume display came on or off.   but once I cleaned it this still didn't fix the problem...)
Step 4.
Use the back side of a butter knife (not the sharp side) to gently slide over the connectors on the iphone. Do this gently as you are only pushing down on the tiny metal contect bars and you should notice the volume display come on again. slide it back and forward. Now the area of interest is about 2/3 along the connection plate to the right.   This is the area that has the infomation sent when your iphone thinks its docked.
This has worked for me and I have not had a problem since I did this 2 weeks ago.   I have since learnt that the new IOS 5 has activated a different part of the bottom conectors. if you have been using dodgy connectors or unapproved apple cables (as I was) any damage or hair and dirt on the terminal this is effecting it. Try it.   just remember if you can do something external to your phone then there lies the problem.
Hope this works for your phone as it did for mine.
Cheers

Strange issue with external monitor, only working when external speakers plugged in (using Thunderbolt to VGA adaptor)

Hey – I am having a very strange issue with my external monitor; where it only works if my external speakers are plugged in and connected.
I am using a late 2011 Macbook pro, running Mavericks 10.9.4, along with an MBox 2 (USB Audio Interface), and two powered speakers (KRK Rokit 5). This setup has had no issues. I have just acquired an external monitor (Benq T2200HD), which I am using with a thunderbolt to VGA adaptor (a cheap Chinese knockoff adaptor).
To start - I plugged the monitor in with the thunderbolt adaptor, and it powers up and works fine. However, there is a nasty buzz coming from the speakers. I did some research and it looks like a simple ground loop issue. I did a bit of troubleshooting, and this is where things get weird.
What I found is - If I unplug the MBox, the monitor loses signal from the computer (displaying ‘No Signal Detected!’). Further, if I keep the MBox plugged in, however unplug both the cables from the MBox to the speakers, the monitor loses signal. It doesn’t matter if the speakers are turned off, however they need to be plugged in (or the monitor loses signal). Weirder still, I can unplug the MBox, however the monitor will work if I plug in the speakers through my macs headphone jack.
Simply put, the monitor only works if there is a direct connection between the computer, the speakers, and the power source. What is going on here? Is the monitor grounding through the computer port, to the speakers (I don’t know how this works, is this possible?). Could it somehow be the cheap VGA adaptor I am using?
Some other information:
- Everything is plugged into the same multi-box for power. I have tried plugging things into separate sources, and the result is the same.
- If I unplug the thunderbolt adaptor, then the speaker noise disappears straight away.
- The ground noise doesn’t appear in my headphones, which are plugged into the MBox.
Any information would be great – am I missing something here, or is this genuinely weird?

Well, I went back into Best Buy to test on 3 other laptops (2 Asus, and their floor model for this Sony). It seems to be doing the same problem so at least I was able to rule out broken hardware issue on my particular laptop.
Here's what I did to test:
Since I couldn't really install Adobe Premiere on their machines, I used the DVIO software (http://www.carr-engineering.com/dvio.htm) and a 5 min clip I captured. I transferred onto their machines, hooked up my Sony D8, and attempted to play the video. It would play for 15 seconds and then stop and jitter with a loud noise (like it does on my laptop). I even tried changing each machine's firewire driver to the legacy one and same results. I pulled a brand new 4 pin to 4 pin firewire cable off their shelf and still the same problem.
I think I've nailed it down to Win7x64 bit Home Edition not playing nice with Firewire driver. Very annoying. I can't find any concrete evidence of this from other users on any of the forums that have my particular problem, but from my own testing, it's all I can conclude.
I have 2 other things I can try:
1. Opening the laptop and looking at the firewire to maybe find appropriate driver (ugh, I don't want to have to open this thing up).
2. Upgrading to Win7x64bit Pro and possibly testing with XP on the new MS Virtual PC (http://www.microsoft.com/windows/virtual-pc/). I can't do it with my Home edition apparantly.
Who needs to view video on an external TV anyways....sheeesh...(scarcasm).

Hello cgoldberg11
Please go to the below link to test if you are having a speaker hardware failure.

This will rule out hardware failure, let me know how that goes.
Thanks
If I have solved your issue, please feel free to provide kudos and make sure you mark this thread as solution provided!

Connecting external speakers

i just got my macbook pro and a led cinema display. i have connected my Harman Kardon SoundSticks to the mbp with a rca jack and cannot see those speakers in the system preferences sound section. the internal speakers and the cinema display speakers show up. any suggestions?
thanks.

When you connect external speakers to your MacBook Pro, under Sound, they will still come up under Internal Speakers, but with the name 'Headphones' instead. Hope that clears any confusion up!
Also, to switch between the display speakers and the Harmon/Kardon externals, just click the name (either Display Audio or Headphones)
Cheers

6th Generation Classic - External Speakers

Previously, I had a 5th Generation Classic iPod (60GB) that when connected to external speakers, had an option (within the Speakers menu) to show large album cover artwork during song play. And when a song was playing, the album cover, on a black background, filled the display.
I'm now using a 6th Generation Classic (120GB) and the Speakers menu does not offer the "large album cover while playing" option. I've search throughout the various menus, and so far, have not found such a setting.
Can this be done on a 6th Generation? (Is so, where's it selected?)

This is the ipod touch forum.
Maybe you should post i the ipod classic forum.

3GS external speakers no longer work and significantly diminished recognization of carrier signal

Recently my IPhone 3GS has, through events unknown to me, stopped emitting any sound from the external speakers (sound quality is perfectly fine from headset). Also, signal strength has become almost entirely diminished, and most often "No Carrier" is displayed (have an additional IPhone 3GS on same firmware without any problems, and is actually a few months older). Not sure if the phone is still covered under warranty, since the weblink is not functioning. Was wondering, even though it may not be under Apple's "Limited Warranty" due to duration of time since purchase, will an exchange for a refurb or possibly a service request be compensated? Just wondering what my options are, especially since I am under a business plan through AT&T and have multiple IPhones for coworkers/"friends" including 3-3GS's and a recent IPhone 4 (not to mention my personal IPod Classic for my evening jogging).

If its under warranty thenmaybe Apple will fix it, they are very easy to come by search "iPhones 3gsdock connector" on eBay and this will show you exactly how to take the phone apart to get to the dock connector, I have brought one from eBay today as I have been having antenna problems with my phone hopefully that will fix it, anyway here is the guide to the iPhone disassembly.
http://www.ifixit.com/Guide/Repair/Installing-iPhone-3GS-Dock-Connector/1546/1
3Gs' are very easy to takeapart all you need is a small Philips screw driver and a suction pad.
Hope it goes well

External speakers suddenly stop working

My 13" aluminum MacBook's internal speakers are working fine. External speakers and headphones were also working fine until yesterday. Now, external speakers do not work with my MacBook at all, and with headphones I get a very muddled, echoy sound. This happened overnight - my laptop was just sitting, not plugged in, on my desk. I've tried restarting and resetting the NVRAM - no help.
I have a 13" Aluminum Unibody MacBook running OSX 10.7.5.
Please help!

>I had a quick look this morning and sure enough, a YouTube clip was playing, but no sound.
This happened to me too using an Tecra A11 unit.
The Youtube clip had no sound but if I plugged and re-plugged the headphone jack, the sound appeared again.
I thought this was a problem with headphone jack but I wanted to check if this issue could be solved by driver reinstallation.
Firstly I uninstalled the Realtek sound driver from the system. Then I entered the device manager and deleted the High definition Audio Controller from the System Devices area.
In Audio , video and games controller I deleted the Intel display audio entry.
Finally I rebooted the system.
After new reboot the Windows recognized the deleted devices. I checked the playback tab in control panel -> sound and found new device Headphones which was not visible before.
Then I started Youtube and checked the sound. It was available. Then I installed the newest version of Realtek HD audio driver and rebooted the unit.
The sound was still there
So hopefully it was just and driver issue

Why has my MacBook Pro stopped outputting audio on external speakers?

Since buying a MacBook Pro in April 2007, I had no problem playing recorded music and Internet radio on external analog speaker systems in two different houses. Suddenly this summer, the audio no longer plays through the external speakers --though it still works fine with the internal speakers. There were no major changes or accidents. The only technical issue I had was the recent malfunctioning of my laptop battery, which Apple acknowledged was defective and replaced yesterday. (I hoped that the problem might be resolved by the new battery. But it hasn't been.) Most of the discussions I've read about audio troubles with the MacBook Pro don't apply to this situation. (The most-discussed problem had to do with the internal speakers no longer working, often because the MBP's audio out port had inadvertently gone into digital audio mode.) My MacBook Pro is a 2.33 MHz Intel Core 2 Duo, OS 10.4.11, The mute button is not on. The speaker sound is up to max. And when I check the Sound status in System Preferences, the info line correctly identifies the speakers. The default ID readout is internal speakers. And the ID reads external speakers when I plug the external speakers into the headset/audio out port, But the sound plays only on the internal speakers, not on the external speakers. I miss listening to my music library and favorite NPR stations on a good sound system, where ever I go. I'd be grateful for any help. Thanks

If your computer was hot it wasn't asleep - it either didn't go to sleep or it work up after you put it to sleep. I've seen both things happen. First, read this article and follow the instructions.
1) For the next few days/weeks pay attention to the blinking light on the front of your computer when you close the lid. Don't put the computer into your backpack/case until it begins to blink. Wait a minute or so after it starts to blink to make sure it doesn't stop blinking - the signal it woke back up.
2) having followed the above instructions, if you take the computer out and it is hot again or if you take it out and discover it has powered down (you'll know this because when it starts up the battery will be drained and you'll see a progress bar over a ghostly display that will eventually become normal) immediately start the Console program and perform a search on 'sleep' and then 'wake'. This should bring up all the recent log files about sleep state changes (going to sleep and waking up). You should see one for when you put the computer to sleep and put it away and the next one should be just after you got it out. You'll find at least one though that shouldn't be there. That will tell you when the computer work up (when it shouldn't have) and might give a clue as to why.
One of the whys could be a magnet that is making the computer think the lid has been opened.

Can't hear VO I recorded over external speakers

- I recorded a VO that I can hear clearly through my headphones when during playback but only as a whisper over my external speakers.
- I have no problem hearing the AIFF music bed that is on a separate track so I know audio is working.
- I'm using an BLUE ICICLE digital adapter for my Shure 8900 microphone that plugged into USB port on back of my monitor.
- All the correct settings seem to appear in my audio preferences.
- Also, on the VO tab BLUE ICICLE appears as Source and Input.
- Once again, I can hear playback through my headphones although the audio waveforms for my VO are only a fraction of the size that they are for the music bed AIFF waveforms.
- Any thoughts on what I'm doing wrong an how to correct?
Thanks

"Doing everything" sounds comprehensive, but is says nothing. It would be more useful if you could simply list what you have done/tried. Because if you truly did everything, then your problem has been proven unsolvable.
But you can't know that, you're awful at logic. I hope you're better with Logic Pro X.

So, I'm recording audio trackson logic 9 through an mbox2. I have my guitar plugged in. Hit record, and I can hear what i'm playing and I can see the wave forms being recorded and all is fine. BUT when I want to hear it back I can't hear anything. The wave forms are there and it's definitely playing because meter things are moving next to the sliders in the mixing window (sorry i'm having a blank and can't think of the right term).
So far i've made sure that "software monitoring" is checked. My output device is definitely the digidesign mbox2. It's not my head phones because I can hear my instrument being played while i'm recording and, I've even gone to the audio midi setup and created an aggregate device.
Can you put up a screenshot of the guitar channel strip and the output channel strip? Just so we can see the complete signal flow from track to output.
Like this:
Software Monitoring on or off does not affect the playback of a recorded track.
Are your headphones plugged into the direct out on the M-Box? In that case you should turn off software monitoring, because you would double up the signal (if it were all routed correctly), which would sound like you've introduced a flanger or even a slapback delay on the input.

External Speakers over AirPort

Am I able to configure my sound settings so that I can utilize my external speakers connected through an AirPort as if they were directly hooked up to the computer? Lovely AirTunes is all I can do.
Thanks for any input.
MacBook 2.0ghz Core 2 Duo 2GB RAM Mac OS X (10.4.8)

OK, how about the firmware on the Airport Express? You can always update that to the most recent version.
Unless something changed in a user-setting in iTunes such as EQ, or perhaps even the "Sound Enhancer" setting, I can't imagine what else would affect the quality.
Have you listened to your stuff in iTunes with headphones on - the stuff that sounds bad over Airport? Does it still sound awful through headphones or directly-connected speakers?

HT1665 how come i cant use other headphones or external speakers with my ipod

how come i cant use headphones or external speakers with my ipod.sood as you plug either in there is no sound.

- Try cleaning out/blowing out the headphone jack. Try inserting/removing the plug a dozen times or so.
Try the following to rule out a software problem
- Check also Settings > General > Accessibility > Hearing. Make sure that the sound balance is not set all the way to "R".
- Reset the iPod. Nothing will be lost
Reset iPod touch: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Reset all settings
Go to Settings > General > Reset and tap Reset All Settings.
All your preferences and settings are reset. Information (such as contacts and calendars) and media (such as songs and videos) aren’t affected.
- Restore from backup
- Restore to factory settings/new iPod.
- Make an appointment at the Genius Bar of an Apple store. Seems you have a bad headphone jack.
Apple Retail Store - Genius Bar
Apple will exchange your iPod for a refurbished one for this price. They do not fix yours.

Problem: I lost the option to get the sound from external speakers or headphones to upgrade to Lion 10.7.3. It accepts only internal speakers. I downloaded Combo directly. I followed all the advice from the Apple community

Problem: I lost the option to get the sound from external speakers or headphones to upgrade to Lion 10.7.3. It accepts only internal speakers. I downloaded Combo directly , without using "Actualización de software". I followed all the advice from the Apple community. Can I use bluetooth speakers to solve this problem? My Computer: iMac. 20-inch, Early 2008. Processor 2.4 GHz Intel Core 2 Duo.

You may need to reset PRAM/NVRAM.
First, check that the jack is clean. Put some alcohol on a plug and insert it a few times. See if that helps.
is your output both digital and analog? If digital, is the red laser light visible in the socket? Do not look directly into the socket when checking.
If all else fails try a PRAM reset:
Reset your computer’s PRAM
A small amount of your computer’s memory, called “parameter random-access memory” or PRAM, stores certain settings in a location that Mac OS X can access quickly. The particular settings that are stored depend on your type of Mac and the types of devices connected to it. The settings include your designated startup disk, display resolution, speaker volume, and other information.
Shut down the computer.
Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Immediately press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
Continue holding the keys down until the computer restarts, and you hear the startup sound for the second time.
DO NOT HOLD These keys beyond the second startup sound!
Release the keys.
Resetting PRAM may change some system settings and preferences. Use System Preferences to restore your settings.
