Crackling and pulsating noise in external USB speakers

How to eliminate crackling and pulsating noise in external USB speakers?

i need to access the Roland's knobs while sitting at the Mac (am using them as monitors in recording etc), so there really isn't a good place to get them further away. By interface, do you mean the PreMobile? that's an interesting idea. I've now tried that (via the line out, the rolands have a single 3.5mm cable, no RCAs); it got rid of the static noise, but the still a loud hum, and the PreMobile apparently doesn't monitor ordinary system sound output (like iTunes). But this experiment does point to the iMac itself being the source of the static noise.
The only AC-powered periphs in the loop are a couple hard drives and a printer (and a USB-powered Wacom tablet; the PreMobile is USB-powered as well).
I've got the speakers plugged into same grounded strip as the mac and the peripherals, trying to minimize ground loop, but it doesn't help.
Someone suggested a ground loop isolator gadget... anyone had success with those?

Can't get rid of noise in external Roland speakers

I have some Roland MA-8 micro-monitor speakers that i realllly like, but i haven't been able to use them with my iMac G5. As soon as they are connected and turned on, they have an annoying hiss/hum, and when i launch Garage Band, there's an additional continuous electronic clicking/popping noise (in batches of three clicks) and static. The same speakers work fine, with just a very slight background hiss, on my iBook. But i want to use them on the iMac, of course.
have tried switching audio cables for others, no difference.
On the iMac, setup is a mini cable from the headphone output to the speakers, and they're plugged into a power strip that is plugged in to the same surge protector that the iMac is plugged into. i also have a PreMobile USB audio recording interface hooked up to the iMac.
I may later post this in iMac G5 topic since it seems to be specific to this G5 (i used them on a prior iMac fine). But i know there can be many audio issues that could be contributing, and it's worst when Garage Band is open.
Suggestions?

IMac 27" Static Noise through external monitors

Hey, I recently bought a 27" iMac and I'm running a pair of Yamaha HS50Ms out for monitoring audio recording. When I'm not playing sound the speakers output static from the computer (presumably hard drive noise or something?). It's especially noticeable when I scroll the magic mouse.
Does anyone know how to solve this?
thanks

-= Guaranteed Solution =-
Hi, I have a Quick and nasty solution. It will work, it's a good test also if this is not the case, however, I bet it is.
The problem is technically a ground loop (http://en.wikipedia.org/wiki/Groundloop%28electricity%29).
The 'Quick and Dirty' solution is to buy a normal cheap double adapter, cut off the earth (I just used pliers) and plug the power of your iMac into this and then your socket, effectively, removing the ground plug to the Mac.
I have messed around ALOT. This is the cheapest complete fix. Be careful when you plug USB's into the computer. I now use a hub for USB, as without the earth you will get some sparks from the ungrounded mac aluminum frame, If this happens don't worry but yeah its not ideal.
If this test works I would then recommend getting a decent RCA Ground noise filter, I don't know if it will cut frequency's of the audio or not, I guess the other option is to try a fully reconditioning UPC unit I haven't tested this yet, I just assume it would work. (cost $200-$600+)
You can also try plugging the Monitors and iMac into the same power board or even better same split power cable. this might have some effect until you really increase power output as the earths are as close to each other. This works for me until I turn my Mackie MR8's up to about 75%. if they are plugged into different power supply I can hear the noise at around 25%-30%.
The iMac actually has an impressive sound card, I have a feeling either it or something on the USB is leaking earth onto the aluminum frame. maybe even the sound card itself isn't earthed properly and runs through the USB earth. It annoys me mac won't provide any kind of solution or admit any of this. ****, I would be happy if they at least sold a ground loop filter on there shop. I know I'm not the only person with Monitor setup and iMac 27" !!!!

I get a static noise on my PC speakers when my iphone4s is close by ?

Phone is not hooked up to speaker system or PC. Just in close proximity. Happens on different speaker systems ( PC, home theater) . Does not happen on car speakers.

This is typically caused by file corruption. Delete and redownload those songs if doing so is free in your country.

Consistant Static Noise noise changes when performing actions on laptop, need he

I have a Sound Blaster Li've 24-bit External sound card which I have my DJ equipment connected to. The problem I am coming across is static noise coming through the speakers. The sound is there when the audio board is powered on?or off. I have already did basic troubleshooting and I refered to theKnowledge Base on this site.
Power of laptop is in a different source, soundcard has the latest downloads, speaker cables are fine etc. I want to check the Bios on my computer but I don't think I am that tactful to do this. Anyways, I will cut and paste my message I started on Mediamonkey.com, I am GDTRFB66. I basically wan't to know if there is a filter or a better sound card I can purchase to knock out the interference the computer is making. I Usually only run 2 speakers, sometimes I will connect smaller speakers through my audio board and run it through source. Also the ststic noise is there when I just connect my computer directly to my laptop and it uses the onboard sound card, so I doubt it is an issue with the sound card.
I really would like some additional help here is the post I submitted on Media Monkey......Next Message

Why is my iPod touch making a static noise?

My iPod touch (2 gen) is making a static noise from the internal speaker. Anytime that I play my iPod from the speaker or headphones, it makes a static and crackling noise. However, it does work when I connect it to my iPod dock. I have tried the five R's and none of them work. What can I do to fix this?

Make an appointment at the Genius Bar of an Apple store.

HELP! How do I get rid of the volume noise that plays when I switch from internal speakers to external speakers?

How do I get rid of the volume noise that plays when I switch from internal speakers to external speakers? I'm trying to watch something on my TV through an HDMi cable (& apple adapter) and when I go to switch the sound control in preferences from internal speakers to SONY TV, the annoying "popping" noise occurs on my TV's speakers.

Go to Edit > Preferences > General > Import Settings and check the box for error correction, and then try one of the problem CDs again.

"Squelchy" noise from external speakers plugged into headphone jack

I get a strange, warmly, high pitched static continuous "squelchy" noise from my external powered speakers when I have them plugged in via cable to the headphone jack of my iPad (3rd gen). The noise occurs only with the iPad - the noise is not present with other devices, such as my iPhone 4S, older iPhone 3G, or my Samsung Galaxy or Toshiba Thriven (both Android devices). Also, the noise is present only with external speakers - never with headphones. Doesn't happen with Bluetooth audio.
The pitch of the squelchy noise seems to be related to how much load the iPad processor is under, though I can't say for sure. I honestly have no idea why it's making this noise. I thought it might be a ground loop issue which occurred only when I had external powered speakers plugged in while the iPad was also plugged in, but the noise happens when the iPad is running on battery, as well.
Does anyone have any ideas how I might get rid of this noise?

I don't know if this could be your problem, but...
On some systems the BIOS will sometimes disable the on-board audio controller at startup if it doesn't detect anything connected to the inputs or outputs (older HP computers did this to me ). You usually need to enter the BIOS and permanently enable the On-board Audio by changing the setting from 'Auto Detect' to 'Enabled'.
Hope that helps.

Audio output will not work on external speakers. Internal speakers will work. What do i do to replace audio output slot

audio output will not work on external speakers. Internal speakers will work. What do i do to replace audio output slot

Right click your volume icon in the notification area and select "volume control options". From there, you should be able to select the external speakers.
I hope that helps!
Best of luck,

No audio out on internal speakers or headphones from external device

I'm using an intel iMac 17" I tried to plug in an external cassette deck, and listen to it through the internal speakers. Even though all system prefs for audio work as expected, and I can see the audio meters on screen operating, nothing will induce it to play sound either through the internal speakers, or headphones.
The audio is certainly going in there, as it recorded perfectly in iMovie. The internal speakers work perfectly for alerts, iTunes, the web, everything. But no external device will work.
I've tried an iPod, a microphone, and a cassette deck, all with the same result. I've launched Garage Band as this can upset the midi player, but it's fine. I've visually checked the settings, no problem.
As an alternative I also tried an iMic and stopped using the jack input on the iMac. Still nothing. I plugged headphones into the iMic, nothing. No audio will play unless it's already on the Mac. External audio goes in there and dies before it reaches the speakers.
All the visual info I get in the sound panel regarding connection options, output etc, is exactly as expected, I just can't get any audio at all.
Does anyone have any suggestions? There's only a few day's warranty left...
Many thanks.

Hello David,
Thanks for the pointer. I looked at the website for Linein, and I already have Audio Hijack pro installed, which contains this application. When I ask AH to record the system audio, the volume meters are dead, I hear nothing, and record nothing - unlike iMovie.
When I do ask it to record, I can hear a thumping sound from the Mac speakers, but nothing else.
I'm really desperate for a solution to this; I can't understand why it's so hard to achieve. If it was just the line in socket I'd suspect that, but a USB connection as well? I don't understand that at all.

When external speakers are plugged in to headphone jack, sound randomly goes back to internal speakers or digital audio setting, then back again

I have an essentially new MacBook Pro with Lion and all updates applied, and am wondering if this is a hardware or software problem. Essentially with something plugged into the headphone jack, things work as they are supposed to for a while, then the sound will switch back to internal speakers, or sometimes 'digital out' (I can watch it change in the system settings), and then often switch back. It doesn't seem to follow any sort of pattern or be related to any specific application that could be open, and happens with different sources of audio (iTunes, streaming from the web), and different external speakers or headphones plugged in.

Sounds hardware related. If it's brand new, and you're still under warranty I would have it checked out.
I have not experienced this on my computer.
As I understand it, you have analog RCA outputs from an 1/8" to left and right RCA outputs. when you're randomly using the computer, it'll switch to internal speakers, then to digital audio, back to your stereo analog external speakers.
This should not be happening and if it's happening with streaming content (I am unaware of anything that streams in 5.1 digital audio) then this must be something that an apple specialist should look at and consider.
Does this happen with the headphone jack out? when you hold your finger over the headphone jack area does a red beam come out of it *blinking* or just on? This will be a good indicator that your audio hardware is faulty. are you running HDMI out?

MacBook Makes odd Static noise ~NOT SPEAKERS~

I have just recently reinstalled Leopard after a hard drive error (possibly caused when I dropped it 4 feet :P), and everything was fine. But I noticed that my speakers weren't as loud as they were and they sounded kind of muffled. Then the MacBook just started making this subtle popping noise, but that stopped after a day, but now it makes this horrendous loud static noise out of no where, and *it is not the speakers* because I turn them down and it still makes the noise. The noise has stopped for now but if I try to listen to iTunes it is VERY garbled. Could this possibly have something to do with the hard drive or disc drive or any kind of hardware issue? Any comments are greatly appreciated!

Just because you turned down the speaker volume but yet can still here the static noise does not mean that it is not coming from the speakers. Since something is damaged or broken you cannot assume that turning down the speaker volume will keep an errant sound turned down also.
Since you dropped the computer from 4 feet the problem could be just about any hardware component, from the hard drive to the logic board.

Listening to external speakers as well as the internal speakers

Does anyone know if I am able to plug in some external speakers into my imac and be able to listen to my internal speakers at the same time. Right now, If I hook up a wireless transmitter to my imac via the headphone jack, to transmit the signal to another room, it disables my internal speakers. I would like to be able to listen to the music while I'm on my imac also as well as transmit it. Any ideas.

Joe
There is no way we have found to use both int. & ext. What I would do is use a splitter and send it to your wireless trans. as well a 2.1 speaker set-up or stereo in the room with iMac.
You can buy a Stereo 3.5 Splitter just about anywhere:

Another one that you may find handy if your going to a stereo or tv!
