Whiring noise is gone in 10.4.8!!!

Has anyone noticed the shiring noise is gone after 10.4.8 update? Mine does!! is yours?

You are right. Actually, I would've preferred the old way (third party stuff to shut down the whine).
At least, Apple should provide some check boxes like in G4 (allow processor to nap) in CHUD tools. For intel they should also provide "allow downstepping of the CPU". That will satisfy both categories of users. My new MLB is almost silent and I would prefer to have longer battery life. Others don't care about battery life, but do care about quietness.

Is my Mac Pro the cause of high pitch monitor noise?

I am encountering a faint but persistent high pitch noise through my Yamaha HS-50M monitors when my Edirol FA-66 interface is plugged into my computer via firewire ca ble.
I've read all these threads which sound very similar to my issue and have tried all the pertinent recommendations presented so far:
Monitor buzzing noise NEED HELP!
Help fixing signal hum/mouse coming out of monitors?
Electric shocks and Noise in a home studio
KVR :: View topic - Interference question. Computer and external audio interface
Just to be clear, my problem is similar but not identical to the problems listed in the threads above. Mouse movement or computer activity doesn't effect the monitor noise I'm hearing at all, it is merely a constant sustained high frequency tone that's emitted from my monitors when my FA-66 interface is plugged into my MacPro via firewire cable. My speakers are silent (aside from their own self noise) so long as my FA-66 isn't connected directly to my computer. Even when my FA-66 is powered on via its AC adaptor but not connected to my computer via firewire cable there is no added noise in my monitors. It's just when I make the firewire connection between my interface and my computer that the high pitch noise appears in my monitors.
I used to run my Edirol off of my older MacBook and never had this issue. I just recently upgraded to a new MacPro and am encountering this issue for the first time.
Since the noise is eliminated when I disconnect the firewire cable from my interface, I believe the sound is being caused by interference from my computer, which is then transmitted through my firewire cable into my interface.
My setup is this:
Grounded Wall Outlet > Furman Power Conditioner > MacPro Desktop Machine > Edirol FA-66 > Monitors
I am using TRS-XLR Mogami Speaker cables to connect my interface to my monitors and am using Mogami cables throughout my system.
All of my audio gear is being powered through my Furman power conditioner: my computer, my FA-66 interface via its AC adaptor (not firewire bus powered), my speaker monitors, and all my other audio equipment.
I don't believe I'm picking up interference from any of my other cables and wiring and this doesn't seem like a grounding issue. Like I mentioned, the noise is gone when I disconnect the firewire cable from my FA-66 interface.
I do have some other hardware in my setup (my computer screen monitor, a USB hub, AC power supplies and cords to power external hard drives, a lamp) that are receiving power from a separate surge protector strip plugged directly into a different wall outlet than the one my Furman conditioner is plugged into. I don't believe any of these other devices are the cause of the interference noise because when I unplug all these items from their respective wall outlet, I still hear the exact same noise when my FA-66 is plugged into my computer via firewire cable.
All signs seem to point to my firewire cable and/or my computer.
Originally I started with a different firewire cable and swapped it out for a newer and higher quality, gold-plated firewire cable meant to cut down on interference. This cable swap did help reduce some of the noise my monitors were picking up, but did not eliminate it entirely.
I then invested in some ferrite core clamps and placed those around each end of my firewire cable (one right by my computer's firewire port & one right by my FA-66's firewire port). This helped a little more but did not eliminate the high pitched sound entirely, just made it even quieter. The hole diameter of the ferrite core clamps is slightly larger than the diameter of my firewire cable, however, and I'm going to order more clamps with a smaller hole diameter that will ensure a snugger fit around my firewire cable. Do you think this may help things more?
I also lifted the grounding pin in my Edirol, tied a copper grounding wire around it and connected the other end to my MacPro's metal case with alligator clamps in an effort to better ground the two suspect pieces in the chain. This seemed to have little to no effect beyond what the ferrite cores were able to clean up. (I got this idea from the GS thread contained in the first link above.) I don't know much about hardware electronics but thought I would try this out just to see if it would help. The fact that it didn't help, to me, seems to reaffirm that the system is grounded properly, because if it weren't I would have possibly noticed an improvement by making a grounded connection between my interface and computer. Please correct me if I'm wrong about this.
I even tried plugging my Furman power conditioner into an entirely different wall outlet, but this didn't change things at all. I do have one more unused wall outlet I can try but don't think this will make much of a difference because I'm 99.99% sure this isn't a grounding problem and that the sockets I'm using are properly grounded. My Furman isn't registering anything abnormal and seems to be functioning properly.
As of right now I've been able to make significant improvement to the noise problem and have eliminated it by 90%. The high pitch noise through my monitors is virtually eliminated but I still notice a faint bit of added noise when interface is powered on and connected to my computer via firewire versus when the firewire cable is disconnected.
Could my MacPro be outputting some kind of interference which is being picked up by my firewire cable and transmitted to interface and monitors? I've read that sometimes a computer's power supply unit can output a large amount of EMI or dirty electrical interference. It seems surprising to me that Mac's professional desktop machine would cause a fundamental issue like this though, especially since it is designed for being able to work in a professional audio recording setup.
Any other ideas people can provide as to what may be causing my added interference and how to treat it would be greatly appreciated. Thanks in advance for your help!

What kind of sound card are you using exactly? It seems like you're sound card is picking up EMI or RFI from your computer when it's plugged into a wall outlet. Are you using a power conditioner in your setup to help clean up your power supply?
Try googling EMI & RFI, there are many online resources which detail how to troubleshoot and deal with these problems. http://www.arrl.org/radio-frequency-interference-rfi
I finally solved my problem by upgrading to a higher quality audio interface (Focusrite Pro 40). This was able to cut out the high frequency RFI signal being output from my MacPro computer. I get the feeling many of Mac's higher end computers tend to output dirty electrical signals which is why so many people have this similar problem.
Try cleaning up your power supply, then maybe use different, higher quality sound cards or interfaces with your setup to see if the issue gets solved. The problem most likely lies with your computer and if you can get a high quality interface that can cut out the noise, that may be your only solution. It worked for me.
Good luck!

Bazaar high-pitched squeal/fuzz noise in iTunes when scrolling.

System info:
I'm using iTunes 6.1.3 on Windows XP Pro, and I'm wearing headphones (i don't have regular speakers).
Issue:
I noticed that if I click and hold down the scroll bars in the Library in iTunes (the scrollbars for Genre, Artist, and Album), I hear a faint high-pitched squeal or fuzz noise coming into my headphones. (If I scroll through the songs themselves, I do not get this noise. It's just the three above-mentioned scroll bars). Since it's pretty faint, I only hear it if nothing else on my computer is sending out music or noise (or only if the noise is also very quiet at the time). As far as I recall, I don't remember hearing this in conjunction with any other program.
Question:
Has anyone ever heard of such an issue? It's not really a big deal, but it does make me rather curious to know what's causing it. Try it on your own computer and let me know if you have the same issue. Could it be a sound card thing? But then why would where I click in one particular program have anything to do with it?
Example file:
If you'd like to hear what I'm talking about (Since you might be tempted to think I'm making this up), I created a wave file recording of it. (I didn't want any mp3 compression to confuse the matter, so that's why it's a wav. Not that I know much about that sort of thing... but just in case.) I uploaded it to here: http://aranel.alasse.googlepages.com/itunessqueal.wav (Sorry it's so big... 5.3 MB... Obviously because it's a .wav file. It's a little over 30 seconds long. )
Process of making example file:
I recorded it using Audacity (which is an open source program that can be downloaded from sourceforge.net). In Audacity, I set the recording/input "channel" to be "Wave Out Mix". I turned the Wave out volume and the master volume all the way up, then pushed record. (Turning the Wave volume up caused additional fuzz, so concentrate on the contrast between the sections of the recording to hear the actual sound I'm referring to.) It's a pretty quiet track, so you'll probably have to turn the volume way up.
It's a 30+ second clip. Here's how the seconds break down:
For the first five seconds, I just did nothing.
From seconds five through 10, I clicked and held down the Genre scroll bar in iTunes.
From seconds 10 through 15, I did nothing again.
From seconds 15 through 20, I clicked and held down the Artist scroll bar in iTunes.
From seconds 20 through 25, I did nothing, once again (I kept doing this so you could hear
the difference).
From seconds 25 through 30, I clicked and held down the Album scroll bar in iTunes. (Notice that this one seems to be slightly higher in pitch than the noise from the previous two scrollings I did.)
The last couple seconds, I did nothing again.
More weirdness:
Changing the volume on my computer (both the master mix, and the wave out mix, and any other mix that exists (e.g. line, microphone, CD Player, Mono out, etc.)), or even MUTING the volume of any of these mixes does not make the sound go away or change in volume at all! It's always at the same volume no matter what I do. I can only make it go away if I unplug my headphones (remember: I don't have regular speakers. If I did have those, unplugging the headphones might only change where the noise is heard.). Changing the wave out volume only affected the recording (which is why I turned it way up. If I turn the wave out volume all the way down, then push record, I still hear the noise coming from iTunes while I'm recording, but if I play the recording back, the noise is gone.
Very bazaar...
Any input anyone?
Windows XP Pro

Called Apple support, they said they do not support the use of iPods in cars, they may have sold you your car kit, but they dont support it. So buyer beware. I have three cars, I upgraded my Nano to 1.1, which is the latest, didnt fix it. I went out and tried it in all three cars, squeals in the Toyota (with Monster Cassette Adapter to Original Radio, hisses in the Nissan (with Audio 3.5 cable to audio jack to after market Sony radio), and works fine in old Mercury (with 3.5 cable to old JVC with audio jack).
So I better take care of the old Mercury.

External Hard Drive not in finder, but in Disk Utility, info gone? recover?

My external hard drive shows up in disk utility, but not in finder. Usually, in disk utility, there will be visible the model/make of the hard drive (such as 232.8 GB MDT MD25...etc), and then below that, there be the actual name of the hard drive that I gave it (such as Jack's External Hard Drive). In disk utility, it only has the first one (the MDT... name) and not the other.
How do I fix this situation? Is my hard drive dead? I don't think it is dead because I can hear it spinning and it shows up partially in disk utility. Oh and by the way, it doesn't give me the option of repairing the disk.
Thanks

Alright, so I bought an external hard drive enclosure. The screeching noise is gone. Disk Utility sees the same "232.9 GB MDT MD25..." stuff, but now also "sees" "ROCK" which is the name I named the hard drive. But the lettering in "ROCK" is gray, not black. Also, its not showing up in finder. When I start up the computer with the ROCK hard drive on, finder says something like, "The disk you have connected was not readable by this computer." I try to verify disk in Disk Utility but it says "Disk Utility Stopped Verifying ROCK because the following error was encountered: Filesystem verify or repair failed."
So buying the enclosure, helped, but it seems the hard drive is damaged or the information is corrupt or something.
What is the problem I am having? (Is it not mounting or is the data bad or whats going on?)
Is there something I can do right now that can make this all better?
My last resort will be to try data recovering software (last resort because it costs around $100).
Thanks for all your help so far everyone.

Grinding noise from PowerMac G4

As the topic suggests, I swapped Hard Disk Drive for boot up and still the noise persists. I thought it might have been a HDD on the way out (unless 3 HDD's have gone at once but they all work in the different bays). Here's the kicker though, when I open the side panel after start up (because I'm frustrated by this problem) the noise is gone. When I close the panel, it returns. I have a Radeon 9800 with onboard fan. If it's that, can I replace the fan or should I take it to a authorised dealer who charges $99 just to open the mac for me. Thanks in advance

Do a web search for "replace fan on radeon 9800" and check out postings like [this one|http://www.techspot.com/vb/all/windows/t-39471-Radeon-9800-Pro-stock-fan-no ise.html] and [this one|http://discussions.apple.com/thread.jspa?messageID=4798974]. I have never even looked into this but it looks like there are solutions, and maybe multiple causes, out there. I also saw mention of Arctic Cooling ATI Silencer 1 (Rev.2), for example at [this site|http://www.velocityreviews.com/reviews/Arctic-Cooling-ATi-Silencer.php].

Crackling noises in Audacity and Rezound, but not in players

I have a new Asus W5A laptop with an intel hda sound card. I have compiled the 2.6.13-git6 kernel with support for this card, and it works quite well. But when I play a sound file in Audacity I get a crackling sound almost like an old vinyl record, this happens with any sound, if I record it in Audacity or import something else. If I try to play the same file in another player like xmms, the noise is gone. I tried Rezound also, and it gives the same type of noise, but less.
I think it might have to do with the fact that there's no Master control in alsamixer, the two controls that has effect on sound output is PCM and Front.
Does anyone have an idea why this happens, or how I can make it go away?

I did a thing I should have done before asking here.
I looked in the linux-2.6.13/Documents/sound/alsa/ALSA-Configuration.txt under Module snd-hda-intel, and there it says to use this option if there are clicking sounds:
modprobe snd-hda-intel position_fix=1 # (or 2)
That fixed it

Help with speaker noises

Hey there,
I have an iMac... with bootcamp on it.
Im having a problem with the speakers everytime i switch over to windows...
when im in a lower volume i hear a distorted weird alien like noise coming from the built in speakers... until i either put in differnet speakers or put in headphones, then the noise is gone...
anyonw know why this happens?? :S
any help woudl be appreciated

I believe so. The "clickity" noises are an option; I like them. You can shut them off via the Main Menu Settings. As for the "whizzing", I'm not exactly sure. It's probably normal, but I can't recal. If everything is working completely fine, then it's probably nothing to worry about, unless it's loud enough to hear over your music, which I doubt.

Noise when using ext dvi monitor

when i plug in my dvi monitor i get loud sound interferrence through my ext speakers plugged into my mbp. if i turn off the seocnd monitor or unplug the dvi cable the noise is gone. This has nothing to do with the cpu

It happens the same to me. I just get the noise when plugin in an external monitor, and when i do the noise is unbereable. I use the MBP to make music!!!

Digital Noise - DVI Port 1 only

Last night one of the two Viewsonic VX910 monitors connected to my G5 went dark and would flicker on for less than a second (showing the correct screen) then blink out. Called Viewsonic and it's under warranty It was in port 1 of the built in AGP card that came with the G5.
Port 2's monitor looked good, so I plugged it into port 1. Anything black or very dark displayed lots of red digital noise - sort of like a TV tuned to a non-channel, but less so and the red noise is only against dark or black backgrounds. All other colors look fine..
Since port 2 was still fine, I assumed the video card was fried by the monitor. I installed a new card (Radeon 9600*) but got the same exact results!
I've run the hardware tests on the G5 from the install DVD. All passed. RAM is good, no discernible hardware failures, etc. Yet the problem persists.
Any ideas? Could the VRAM have gotten friend or corrupted? Or perhaps I might want to reset the PMU? Guess it couldn't hurt, but I don't think that could have done it.
Thanks in advance for any insights you might have.
* BTW, the 9600 card would only boot in Safe Mode. It was actually fine until I installed the ATI software. DUH! But apparently, that is a known incompatibility with some G5's - as mentioned in other threads here in the Apple forums.

In the interest of the discussions, I am posting the 'fix' for future campers with this problem.
I changed the refresh rate from 75 to 60 hertz and the noise is gone! I don;t remember setting it there but who knows what the viewsonic monitor decided it wanted to make it;s last request...

My speakers are making a stuttering noise and the mouse is flickering random software glitches

Hi
as soon as I boot my speakers are making a stuttering noise unless I turn them down to nothing. this noise will continue while I work if I turn my speakers up.
But if I watch or listen to anything the noise is gone.
The mouse flickers and links on the desktop open without me wanting them to.
When I go under the Apple Icon TRHS the menu flickers and behaves strangely.
What could be happening ?
Thanks for any help you can give me.

Thanks for your replies, I have done a re-boot from disc utilities and repaired and verified disc and permissions.
This cleaned it up. But then I logged into LinkedIn using Safari ....the program froze when asked to link to one of my contacts. All of the bugs then returned. Only the combo of LinkedIn and Safari cause the problem . Other browsers work perfectly.
I would like to eliminate all bugs this combo causes - does anyone have a fix ?

Boot drive access/noise...normal?

Greetings again.
Been using my new MP for a few days now and it's great, but have noticed something along the way I'm curious about.
My Boot system drive seems to be constantly accessing, even when not doing anything. I can hear the sounds (seems like the normal "soft grinding" noise they can make when writing - i don't want to say it's clicking or thumping). It seems to happen a lot. If I open activity monitor and view the active processes it changes by the second, so it appears that this is just something the system does. Oddly, the drive seems to make less (smoother) noise when writing large files.
It's noticeable when doing nothing or doing small things like running the screensaver, or even typing this post.
Considering having a number of drives in the past, it doesn't sound alarming or anything but is noticeable. I have a second external (same kind) which seems to be much quieter when writing.
I just wondered if anyone else experiences this, or if it's normal or sounds like something I should be worried about? I verified with DU and seems okay.
Otherwise, thank you, and I'll enjoy the machine.

The Western Digital drive in my 2009 Mac Pro started making the same noise after beeing very quiet the first couple of days. It lasted for a week or so but now the noise is gone. It could be the S.M.A.R.T system in the disk is doing something to the disk. But I'm no expert...

Terrible noise appears when it wants and as long as it wants

<hi @ all,
I have a Creative x-fi music running on Win7. ?
Normally i have an amazing good sound, but sometimes just out of a sudden it gets terrible (a terrible noise comes to the foreground and the normal sound gets "deeper"). This just appears whenever it wants to.
Sometimes right after PC start for like 2secs, sometimes when i have the PC running for like 0hs without problems.
It suddenly comes and suddenly goes. There is no "program" i started before etc.
And it lasts as long as it wants to, sometimes secs, sometimes minutes (till i restart the pc).
Like:
I start the PC, close all programms running?<span class="lia-user-name UserName" ?<span class="lia-user-name UserName" in background and start VLC to watch a movie.
The movie runs for 2hs without any problems. Suddenly the noise appeary without me even touching the mouse.
2mins later the noise is gone.
I already tried different drivers. The onBoard soundcard (which is deactivated when im running the creative card) has no problems.
Anyone know what this could be or even better how to fix this? Ive really no idea.
Or anyone experienced <span class="lia-user-name UserName" this problem before?
Thx for help,
theNick

Irregular and annoying HD click noise (mostly in idle mode)

Hi there,
do you know the "click" noise your MacBook HD makes when you shut down your laptop? Yes?
Well, it seems my MacBook HD makes just that noise at irregular intervals, especially in idle mode (i. e. when no programs are running and nothing much is happening on my Mac ...). It's quite an annoying tick and especially at (quiet) night time can drive me up the wall.
From Activity Monitor, I can't see any disk access happening which coincides with the "click". Sometimes, shutting down the MacBook, waiting a couple of minutes and then restarting it makes the "click" disappear for a while, but it always comes back eventually.
I really would like to know what is happening here ...
Yes, I know that there are a few other threads here about just that topic, however, I don't think anyone has yet identified the true source of the "click":
It's definitely not a hardware problem since I have observed the "click" on now three different MacBooks, all using different drive models and makes (Seagute, Fujitsu etc.).
Any insight into this issue would be highly appreciated.
Kind reagrds from Berlin,

Hallo everybody!
after having managed to solve the problem on my own the whole night and after a morning visit to the nearest Apple Service point, I got a solution, which I hope is not a mere "workaround".
Just to summarize: at the Apple point they told me immediately that such a noise would be absolutely normal; in particular, they told me about the "journling" of the HD the System is used to perform periodically in background (that sounds me strange, as I noticed no real activity when the noise was present). They suggested me verify the hd, initialize it and reinstall the system.
I did so and magically the disturbing noise was gone: as I anticipated above, I hope this struck at the root of the problem but I'll wait and see what is going to happen when my HD will be almost full again...
In conclusion, I thing the reason of the problem could really be some bad piece of software continuously causing "fake" HD accesses... it should be nice to know which piece of software it is.
Bye

Early 2008 Mac Pro (8 core) Cabinet Noise

I noted that this discussion was archived, without a solution being posted. Many people seem to be experiencing this odd Mac Pro noise that comes and goes. Some users say it is a fan, some the PSU, others say its the disk drives.
I have experienced this noise for years. While some of us will of course have different causes, I found my problem, but as yet do not have a fix that I like. Given the cost of a Mac Pro, for their overkill cabinet to have a noise problem that impacts mutiple (many?) users is ridiculous. My son's $750 HP desktop makes no noise. Apple, are you listening?
My noise, a loud buzzing that stops and starts at random (and will go away on its own for weeks) stops when the side cover is removed. I added black electrical tape at all spots where the cover touches the case, but no change. Then I put tape vertically down the rear latch for the cover and the noise was gone. It returned months later (tape came slightly loose?) and I then fixed the noise by not closing the latch all the way. So far so good, but this a lousy way to "fix" something.
My system has all four drive bays full. Three of the drives are third party hardware.
I blame the case/latch engineering and Apple is the responsible party. I wonder if they re-engineered the latch in later models, as the complaints seem centered around the early 2008 eight-core.
I hope this helps others.

I had the same sound, i also had drive in all 4 bays, i think once i fixed it by making sure the drive were all the way in, i have noticed it hasnt come back in the last month or so since i got my SSD. Its a shame this thing has an issue like this, since otherwise i love the case ( it looks like it could take a bullit for me )

Whiring noise is gone in 10.4.8!!!
