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 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:

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.

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?

Windows 7 Volume Adjustment Feedback Noise

Hi, I just installed Windows 7 on Boot Camp (I'm using Snow Leopard on a Macbook 5,1) with the latest Boot Camp 3.3 update and whenever I use the volume media button on my Macbook's keyboard, it changes the volume in Windows 7 while playing the feedback noise (like on Mac OS).
Is there a way to turn this off? It's rather annoying to me.
Thanks for any feedback, I appreciate it.

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.

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.

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 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????

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?.

Terrible feedback/noise using jamlab with macbook

I don't know where else to post this. I'm sure it's a macbook issue, as I used the same jamlab with my mini.
Whenever I use distortion (i've been playing guitar for over 15 years, so I know how much distortion is too much etc... in this case, anything in the 'saturated' range) screams feedback, even when using headphones. I only use headphones.
I also bought a preamp to see if it was an input/gain issue. No Help.
Here are some things I've tried:
- Using aggregate device to use headphones out of macbook, input of jamlab. No help.
- Muting all unused devices (built-in mic, line-in etc..) No Help
- Unplugging from power source. No Help
- Using different USB port, turning off bluetooth, wifi etc. No help!
Something interesting to note; when looking at the meters and the noise is present, they sit flat, not necessarily redlining, but they're not pumping, they're hitting a wall. The screeching feedback only occurs in the absence of notes. When I select 'no output' on the channel the levels are empty and respond as they should when playing guitar. They bounce when I play, remain silent when I'm not playing. However, this is pointless because I want to hear what I'm playing. The meters also behave this way (normal) when I unplug the headphones (not routed to speakers or any other to-air output)
I'm been getting into amp sims lately, and this is just annoying the **** out of me. A noise gate would be of no use because I'm incorporating volume swells, rests, and sustained notes...for me a gate just ruins all those things.
Anyone else experience this? I have the latest driver as well.

You should have a line-in jack right next to the headphone-out jack on your Macbook, no? Then in GB's Prefs choose built-in for you input.
I strongly doubt that the line-in would pick up anything from an iPhone headset. You would have to untangle the in/out wiring of that headset, and then the level would still be much too low for a line-in. Think of all the stereo headsets that work with Windows machines but not with a Mac because it has a line-level input and not a mic-level.

Loud pops and feedback noise

Hi All,
I have been having bad sounds and noise problems since I first installed Itunes 7. The first and most annoying problem is when I play a song or sample, and the song stops, or I hit pause, the program begins playing this incredibly loud and annoying electronic "feedback" sound (almost like a bad techno song beat). It will keep "playing" until I start another song. I just updated to the newest version of Quicktime (7.1.6) and that did not solve the problem.
The second and less serious problem is that when I am inporting a CD, and the songs start playing automatically, the sound is at a very nice volume. But as soon as the import ends, the volume drops substantially (often right in the middle of a song).
Any and all help would be greatly appreciated!
Thanks folks.

Loud feedback noise on M

Several months ago I had purchased one of those RadioShack Hedsets.
When I use the mic I always have loud screeching (feedback) type noise when I turn the volume on my speakers up and I don't know what to do.
I currently have Soundblaster augidy SE

KevinPhomma,
Can you mute microphone as a playback source? (Some cards have a "Record without Monitoring" option for this purpose.) Also a directional microphone might reduce the feedback.

Waveform editor feedback noise

I am using STP 2.02 and working through the Soundtrack Pro book by Mary Plummer.
When I load a file into the waveform editor (page 32), it immediately starts making a horrid noise, it seems that it is picking up feedback from the built in microphones.

If you look at the Recording tab in the upper right pane and switch the output to None it should solve that problem.

For my part I don't quite see why it would be designed so that one is armed for recording in the Editor window, but whatever.

Feedback Noise: WoW Wireless Headset.

I've had my headset for almost a year and overcome several difficulties surrounding it. However I can't seem to solve this one. There is distinct feedback coming and going and it's getting very frustrating. There was also a point in time where the headset would for no reason make me sound like a robot, and I wonder if this is linked. I'd like some feedback, or help regarding it. It makes talking on Ventrilo difficult.

Hi,
Have you upgraded the firmware?
