I have this high pitch sound that started intermittent this morning .
Now it's getting more frequent and last longer.
It just stopped when I moved the power saver setting of the video from never to an hour.
I'm not sure where it's coming from yet.
I'm pretty new here, though I posted over a year ago here with a few questions as a beginning switcher. My switch completed in Christmas of 2005 with a late '05 Power Mac G5 Dual-Core 2.3GHz with 1GB RAM and 250GB HDD. I decided to get another monitor and it is a Sony 19" LCD one. I also didn't get any speakers since I used headphones a lot at the time. I recently decided to start using speakers. So temporarily, I am using the Altec Lansing BX1120 2.0 Stereo speakers from Walmart for only $15. They sound great but I would like 5.1 surround sound to watch my DVDs (and to soon upgrade to BluRay & SACD/DVD-A; but that's for another thread later on). Before I go on, I would like to ask questions and provide facts with what my 'puter has. My specific products I'm looking for is at the bottom of this message.

After a couple times of doing this it would eject the disc, so I figured I would try another disc, I have tried many different discs such as games, cds, programs and nothing has worked.

If you've ever heard the "mosquito ringtone", that's basically what it sounds like. Really odd. It's definitely got something to do with the screen brightness, and I basically can't use my laptop at medium brightness because the sound drives me a little nuts. Turning the brightness to the lowest setting makes the sound less intense, but it's still audible.

I have heard that macbook pro 13" models might be able to use the new processers due to their lower energy useage. I presume that I will be able to take my mac to an apple store and have it installed. Is this information true?

I've noticed on my MacBook Pro (late 2013 with retina, 13", 2,4GHz i5, 256GB SSD, 8GB Ram) that when I run the display on low brightness, there is a high pitch noise coming from the screen (inverter problem)? It seems as it disappears when adjusting to either a high brightness or turning it to zero.

View 4 Replies View RelatedI just bought a pair of the Rokit 5 external speakers. When I plug them into a Mac Pro (Tower) I get a high-pitched hum from the speakers each time I try to play a sound. So if I go into System Preferences/Audio, and I try to play a sound, the high-pitch is heard as the sound plays, and for a second or two after, then it goes away, and is heard again each time I try to play a sound. Same with when I play something thru iTunes or any of my audio apps.
If do the exact same thing playing from a Macbook, I do not have that problem at all, the sound is nice and clear with no high-pitch sound.
I have the speakers plugged in using 1/4 inch jacks to an external sound card (MBox), and this audio card is plugged USB into the Mac.

Hey guys, got a little issue here. I have had a MBA since about march of this year. Just recently I on two occasions the computer has all of a sudden had this loud high pitch whine. It has only happened twice and at both times (if I remember the 1st time correctly) I wasn't really doing anything on the computer. Today specifically it was just sitting idle on my desk. Not sure where its coming from maybe speakers? Any idea to what this is? Should I be setting up an appointment to see a Mac Genius?
View 10 Replies View RelatedWhen I turn it on it runs fine for sometimes about a minute (sometimes less) before it just turns itself off! After it turns itself off I'll hit the power button and it emits a high pitch squeal from the machine whilst holding the button. If I then remove the battery from the Machine depending on how long I leave the battery out and put it back in, it will then power up for a short amount of time. Sometimes I can get it to the desktop and open System Profiler for example, other times it gets as far as the Apple grey screen. I've ordered a power adaptor as I didn't get one with the machine but as far as the battery indicator goes, it's on 96% and all four green lights are on the battery indicator on the base. Has anyone heard of any problems like this before?I believe it's running a 500mhz processor and has 512mb of Ram.
View 3 Replies View RelatedI have a Power Mac G5 2.3Ghz dual-core system (M9591LL/A) with 2.5GBs of RAM and an Nvidia 6600 PCIe graphics card with 256MBs of RAM.
I tried playing a full-screen HD episode of "The Office" on Hulu.com and it was extremely choppy (like 0.5fps). The sound was fine. It's still quite choppy (~2fps) in a normal browser window (not full-screen)
Is this normal? Does this video card not support it? What is the most powerful card that can be installed in this machine? I'm not opposed to buying a PC card and flashing the ROM if need-be.
I'm holding out for a supposed 13" i3 mbp.
I've got a Windows machine with a Pentium D 2.3ghz and 3g ram.
Using Photoshop or video editing software, what type of performance gains, if any, should I see with a .26ghz core 2 duo and 4g ram? What about with the i3 and 4g ram?

I have a new 27" I7 that appears to have the high pitch sound issue if the brightness is not at max or lowest. How "common" is this issue?
I do not need the perfect iMac (I have some gray banding and the 1TB HD grumbling and it is not a big issue to me) I just wanted to see if this high pitch noise is considered a defect and needs to be fixed/replaced or it is more common than not with the iMac.
I just bought an iMac 24" 2.8Ghz Dual Core, 2Gb RAM, 320 HDD. This nice iMac has been with me only 2 days and the problems already started. I don't know why when I play a song either in iTunes or in web(audio streaming) the audio suddenly changes. It's as if you applied an EQ and removed all the low frecuencies and after a few seconds the sounds returned just as normal. When this "auto EQ" happens, the sound becomes "brighter" (I hope you understand what I am trying to say) but just as I said, after a few seconds, the sound is played normaly. I am running Mac OS X v 10.5.2.
I have a 24" aluminum iMac G5. I have never had a problem with sound before, and feel like this problem is isolated to a certain DVD but the DVD works on EVERY other player I own. Everything pretty much plays DVDs, so that's many!
So here's my problem: There's parts of this movie that have very high pitched sounds, like electronic sounds that are just sound effects in the movie. Whenever I get to those parts in this movie (maybe even other movies for all I know, I don't play many) and the sound goes quiet, like the speakers can't handle that high pitched sound.
I feel there must be something I can do about it, right? I just use the regular default DVD player application that pops up when I put a DVD in. I tried playing with that equalizer but nothing changed. Any ideas...?
I can't make my display to sleep on both battery and power adaptor default setting. Aside the switching graphic cards problem, I found this can effect the battery life as well.
View 10 Replies View RelatedI am SERIOUSLY considering throwing my PC away and buying an 8-core MP. But I don't know if I will need a better sound card. Sorry, I tried researching this up but I'm still confused.
Is the sound card in the MP good enough? I am not a musician, I just want good fidelity for music, and stereo is all I want. I have a Creative (guess it's the SBLive) today in my PC.
What type of output connectors does the MP have? I saw posts mentioning optical, but I have 2.1 Altec Lansing baffles and I'd like to continue using them. They do NOT have optical input. Just the normal mini-stereo adapter.
I also suppose there is some kind of microphone input somewhere, I need it for skype VOiP (hope it works well on OS X).
When I am watching shows in high definition, I am not getting high definition sound out of my Mac mini. I have my Mac mini connected using an HDMI cable. I would think that I should at least be able to get Dolby 5.1, but right now, I'm not getting any high definition sound at all.

When I connect to an HD TV using the Mini DisplayPort (via a Monoprice Mini DP-DVI dongle and a Monoprice DVI-HDMI cable) and to a Hi-Fi system using the headphone out, the Hi-Fi speakers emit a loud and persistent high-pitched whine.The whine disappears when I disconnect the Mini DP dongle, and also when I disconnect the audio cable so that the sound is playing through the internal speakers. There's no whine when I connect earphones to the MBA instead of the Hi-Fi. I don't have another external display with which to test the issue, so I'm not sure if this sound exists when the computer's connected to, say, an ACD.I'm surprised that this problem doesn't seem to have been mentioned on this board, but it's well documented on the Apple boards (1, 2, 3, 4). The consensus over there is that it's a fundamental design flaw in the MBA and that the only solution is to get a ground loop isolator. Has anyone here had the problem and been successful in getting it fixed by Apple?

If you're having this problem, try adjusting your brightness. I was experiencing this issue today, and depending on where my brightness slider was... it got worse, better, to non-existant.

View 5 Replies View RelatedI just bought the macbook 13" (white casing) today and the first thing I noticed when I turned it on was the fan, it was extremely loud!! I let it run for awhile and it was still constantly loud. Then I tried rebooting twice and still the same problem. My room is only around mid 60F. Is there some function I'm supposed to turn off? Or did I get a lemon macbook?

2 days ago i received my new mac pro 6-core 3,33GHz...now something really weird and super annoying is going on with this computer...From time to time there is this really loud POP trough my speaker. I'm absolutely 100% sure this has nothing to do with my amp. cables or whatever and its definatly a problem with the MacPro, i know because of the following:
Plugged in new cables, removed every installed software, plugged onto different amplifier, when there are absiolutely no audio cables plugged into the computer and when i use the build in speakers of the mac pro i still hear the POP/distortian like sound, and finaly even took it at my friends house and tested the machine there on his audio instalation...problem remained! not knowing what to do next i decided to go and see a very good technician (music instruments and studio recording) and told him about the problem, he imediatly stated that it "could be" because of the harddisk drive giving like electric impulses or whatever that causes the distortion...or that the sound card or audio chip set waking up from sleep and every time it does there is this loud POP?..................
I searched the archives and I can't believe no one has mentioned this yet! This is a huge problem on both my Rev A and my new Rev B. When you connect an external monitor and external speakers using the headphone output, there is a high frequency ringing sound coming out of the speakers. I've managed to live with it by turning the treble to minimum and keeping the volume low enough but at the expense of sound quality. The strange part is, if you disconnect the monitor, the ringing sound stops. The problem only occurs if you have speakers and monitor plugged in at the same time. I've tried this on my Samsung monitor, my SONY TV, and my Panasonic audio receiver. The problem occurs with both Rev A and Rev B while my white MacBook and 2007 MacBook Pro all sound fine.
