Speakers getting a feedback noise.

I have a set of BOSE Companion 2 series speakers, I keep on hearing a feedback every so often. I was trying to find the solution, but I can't. I have them hooked up in the Headphone/speaker jack on my new I-Mac 20" 2 GHz Intel Core 2 Duo. I also have a Belkin USB Lighted Hub with a Western Digital usb external Hard Drive. I just don't want to ruin my new I-mac with some sort of power surge, or is this normal. Can some one give advice?

Sorry I was typing the question up and posted it in the wrong spot. I believe I have figured it out.
I have unplugged the speakers from the computer, but left them plugged into the wall plug. They still made the feedback noise. I am guessing it has to be from a different source or the speakers are faulty. I have never had a problem with any other speakers, so I was thinking it might be them.

Feedback noises while charging

I have a audio out cable linking my 4th gen Nano to my car stereo. With this combo I've never had any noise issues. Today I bought a USB plug and patch cable so I could charge my iPod while driving. Now I'm getting terrible feedback noise when the. USB cable is plugged in. Any suggestions?

Contact the vendors and/or the car dealership. One or the other should be able to advise you.

I have a macbook pro 15 retina - when ever I connect to bluetooth speaker, I get this loud noise coming from the speaker - if I turn bluetooth off, the noise is now coming from the macbook speakers

I have a macbook pro 15 retina - when ever I connect to bluetooth speaker, I get this loud noise coming from the speaker - if I turn bluetooth off, the noise is now coming from the macbook speakers & stays until i restart.

Hi John. Thanks for that input. At Step 6, after clicking "Next" I get a window telling me my OS version is unsupported and the installation may not complete. I am prompted to go to Canon's web site to "Check Latest Info".
I've had this window on previous attempts and from Canon's web site I downloaded two drivers as follows
- ICA Driver V4.0.0
- Canon IJ Network Tool V4.5.0
I'm not sure if these are the correct / complete drivers I need for this install or not.
I continue to follow all the steps. At step 9 I click "Wireless Set Up using USB" amd get a License Agreement (a little different than instructions)
I click "Agree" and it goes to a Setup window with two progress bars showing the installation. I've not been prompted to connect the USB?
After the Setup window is done, I am then prompted to connect the printer via USB. I connect the printer and click on "Redetect". It is not detected.
I then try following the Canon on screen instructions for connecting to the wireless LAN amd enter the password. It searches and indicates "Connecting" on the window, but it never connects and the blue light just blinks
So, at this point I am stuck??
Thanks

Why do I get a humming noise from my stereo speakers when I plug in airport?

Why do I get a humming noise from my stereo speakers when I plug in my airport?

Temporarily, please turn off your amplifier and/or powered speakers and disconnect the plug that goes into the AirPort Express audio jack.
Plug a pair of headphones directly into the AirPort Express and listen for a few minutes.
Do you hear the "hum" that way?

Feedback noise from computer speakers

my computers are emitting feedback noises when I turn the volume up. if i plug in headphones, i can hear the tapping of keyboard keys, and anything that's happening inside the computer. What do I do to fix this? Why is this happening?
please help me!

Same problem here!! no matter if speakers or headset is being used the feedback is terrible, even the volume if the mic is automatically turned down ( I guess to avoid the weird sound). the sound hardware checkup only finds that mic detects sound and that speakers make noice so it figures out that sound is ok
any ideas????

Really Annoying Feedback Noise

Does anyone get feedback on speakers of all types when their iPhone is on and near? I, so far, have received feedback noise on both home, work, car, and conference call telephone speakers. It appears to start when the phone attempts to wirelessly sync up to receive new email and text messages. This has become a problem because I can't seem to listen to the music on the phone without getting extremely loud feedback. And it was embarrassing during a conference call when the phone was causing the feedback within the phone overpowering those speaking on the phone. Any suggestions are helpful.

Though maybe not entirely identical I have noticed RF interference and also iPhone speaker crackling while playing music at home(I have a Wi-FI network). I was listening to a song out of the built-in iPhone speaker and all of sudden had terrible crackling - so while the song continued to play I turned off the Wi-FI connection on the phone and it after a minute the song quality went back to normal. So was this RF interference, WI-FI related or the fact the iPhone was going out to get new emails?

Feedback noise from iOS4 upgrade to 3GS

Dear Apple marketing folks, we appreciate your developers, but please get us a patch for this iOS4 issue ASAP. Think of the bad (and very public) experiences that are now happening daily with iPhones randomly making loud screeching noises in work places, cafes, buses, subways, etc.. Talk about bad word-of-mouth marketing. Ouch. The Android marketing people are going to have a field day with this one if it does not get fixed quick.
The recent upgrade to iOS4 on my otherwise great 3GS is causing random, loud, high-pitched, feedback noises to emit every time the phone makes a noise for anything else (reminder ding, etc).
A phone call with tech support only got me a suggestion to do a Restore via iTunes and confirmation that they know this is trending up. The Restore did not work.
Other threads listing the same issue:
1. http://bit.ly/bzAf8Z
2. http://bit.ly/cg1hKo
3. http://bit.ly/agbFAY
4. http://bit.ly/auDYNx
5. http://bit.ly/bTxsBT
Lots of blog mentions on the issue just like this one from iLounge: http://bit.ly/eA1rU.

I have had the same issue following my upgrade to iOS4. In my opinion these issues are uncharacteristic of Apple. I have had no issues with this phone or any other Apple product that I have used until I made the upgrade to iOS4. I agree with the other posts that something needs to be done about this (and other iOS4 issue) ASAP. PLEASE post any tricks that you have found (besides restores, and reboots which I have already done without lasting success)to work on a more permanent basis.

Flex 2 - Persistent Feedback Noise

Hi everyone,
I've had my Flex 2 since about December and ever since I opened it there has been this recurring high-pitched feedback noise emitting from the computer whether I'm running things on it or it is simply idle (i.e. at the desktop). It is also persistent whether the laptop is charging or on battery power. Anyways, I sent it in to Lenovo about a week after opening the laptop and they sent it back saying the issue had been repaired with the motherboard being the cause of the issue. As soon as I turned on my laptop, the noise was still there. However because I needed it for school, I couldn't send it back in til Spring break. They then contacted me saying that they couldn't identify the problem I had stated and even after describing to them in detail the issue, they could not identify the problem. At this point, I needed my computer back for the new school quarter and so had to request that they return my computer to me "unrepaired". The feedback noise is still persistent and annoying as ever but it seems I'm out of luck with trying to get Lenovo to help me with this issue. Has anyone else dealt with this problem? Also, the noise comes on and stays on whenever I go to configure the microphone properties in control panel. As soon as I close out of that, the noise switches back to being an on-and-off noise.

No proper fix. Workaround is to uninstall the Realtek driver and use the generic Windows driver.

Nokia 6300 high pitched whistling feedback noise d...

I am now on my fourth Nokia 6300 having returned the previous three because of the same high pitched whistling or feedback noise during a call. I have also tried updating my SIM card (a genius at Vodafone came up with that idea) and still the same problem.
I know of a couple of people with the same phone and no problems, so I can only suppose it is something to do with the Vodafone software.
I would be happy to try updating or re-loading the software but cannot find it anywhere?
I really like everything else about this phone so any helpful suggestions would be appreciated!

I also recently upgraded my wonderful 6233 with a 6300. The ear-piece of the first one I got produced a constant buzz during calls. Returned it, got a new one on the spot. After a few days, I started having complaints about my audio at the other end; the symptom was a very high noise level (coming from my end) together with echo (the caller would hear their voice echoed back). I had also started noticing a distorted low-level replica of my own voice present at the ear-piece. The first thing that came to mind was "oh no, another replacement!". Being a bit of an inquisitive mind though, I decided to debug this a bid further. So I browsed the web, and among other things came across this thread. The turning point was correlating the problem with reports of Bluetooth incompatibility from various users right and left; as it turns out, the 6300 appears to have a serious Bluetooth "problem". To make a long story short, the situation is as follows. After the phone is turned on, all is well: audio at the other end is perfect (no noise, no echo). Then I turn on my Motorola H700 head-set. Call the phone from a land-line, and yes, the noise level is high as hell; the mic gain is turned up so much that you can whisper a couple of meters away and hear yourself just fine on the other end! Here comes the catch: turn off the Bluetooth head-set, and surprise-surprise, the problem is still there with the built-in mic; turning off and on the phone cures it. But wait, this doesn't happen always. Sometimes the mic level goes back to what it was before, and the phone is working fine once more, without power-cycling.
That's more or less it; I hope it rings a bell with someone reading these lines, and hopefully it gets fixed in a future firmware revision. In the meantime, I need a new Bluetooth head-set...

Feedback noise

So my phone has been cracking up a bit on me. It's been freezing up, getting very hot, and just generally been slow lately. But today, it did something unique. I went to dial a number on the keypad and upon telling it to call, the phone cut out of the call and began making a terrible feedback noise. Think Jimi Hendrix in my phone. So I immediately hit the home button to get out of there, but it kept going. I had to reboot it to make the noise go away. It made the noise all the way until it was totally shut down.
Any ideas? I don't really want to go to the genius bar again. This is already my second iPhone, my first was replaced due to constant unexplainable dropped calls.

Mine is doing the same thing. Someone (Jimi Hendrix too) is saying, "hello, hello!". It done it several times. I have no idea what's causing it with mine. It works perfectly except for that. Sounds like someone else is using the line. I've wondered if it was a portable phone somewhere around.
If it continues, I'm going to call AT&T. I believe it would be "their" problem since they control the frequencies.

Feedback noise from microphone

I have an HP Pavilion desktop p6674y. I plugged in the microphone on the rear panel. The microphone works and I can record with it. But the feedback noise that comes through the logitek speakers makes it impossible hear the audio recorded over the noise. How can I eliminate the feedback noise?.

Quit Mail, Trash this file...
Safe Boot , (holding Shift key down at bootup), use Disk Utility from there to Repair Permissions, test if things work OK in Safe Mode.
Then move these files to the Desktop for now...
/Users/YourUserName/Library/Preferences/com.apple.finder.plist
/Users/YourUserName/Library/Preferences/com.apple.systempreferences.plist
/Users/YourUserName/Library/Preferences/com.apple.desktop.plist
/Users/YourUserName/Library/Preferences/com.apple.recentitems.plist
/Users/YourUserName/Library/Preferences/com.apple.mail.plist
Reboot & test.
PS. Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.

Installed "Intrigated gmail" and now i get a siren noise that i cannot stop. uninstalled firefox and reinstalled but cannot stop. unistalled all add ons cannot stop. need help

Installed Intrigated Gmail and right after that everytime I open firefox I get a siren noise that will not stop. I uninstalled firefox and reinstalled with no add ons they where all uninstalled and I still get the siren. If I cannot stop it i will be forced to use a different browser.
== This happened ==
Every time Firefox opened
== 5/21/10 6pm

Check the home page setting:
* https://support.mozilla.com/kb/How+to+set+the+home+page - Firefox supports multiple home pages separated by '|' symbols
* http://kb.mozillazine.org/Preferences_not_saved
It is possible that there is a problem with the files sessionstore.js and sessionstore.bak in the Firefox Profile Folder.
Delete the files sessionstore.js [2] and sessionstore.bak in the Firefox Profile Folder.
* Help > Troubleshooting Information > Profile Directory: Open Containing Folder
* http://kb.mozillazine.org/Profile_folder_-_Firefox
If you see files sessionstore-##.js with a number in the left part of the name like sessionstore-1.js then delete those as well.
Deleting sessionstore.js will cause App Tabs and Tab Groups and open and closed (undo) tabs to get lost, so you will have to create them again (make a note or bookmark them).
