High-pitched sounds are muffled to the point of inaudibility

I don't know how to describe it exactly, but Tiny Tim's "On the Old Front Porch", I can't hear the falsetto parts without going into VLC and changing the equalizer every which-a-way. This is concerning. I know this file is good, I've listened to it before. Is there some thing that makes my system default to a weird equalizer or something? MPD and mplayer both play it the same way; VLC plays it that way by default, too, but if I mess with equalizer/spatializer I can get the falsetto parts out to where I can distinguish them.
Anyone know wtf is going on here? I have a Xonar DX. Help greatly appreciated.

I've just enabled my onboard sound and found that it plays the same file fine on the speakers, whereas when played through the Xonar DX, the higher sounds are muffled. So I guess that seals that the Xonar is defective?
It might have been a problem with the speakers, but it's unlikely that both the speakers and your first HPs break at the same time.
But, the same thing does not happen on all ports; on some, the higher sounds sound correct while the lower ones sound incorrect (i.e. the opposite problem).
The speakers wouldn't know to which port they are connected, so this must be the card.
Your problems sound as if the card's output stage doesn't get enough power, so there might be a problem with the power supply. Could you try reseating the connector?

High pitched sound (not from the speakers)

I bough an A665 on may 21st 2011, and since day 1 ive been hearing a high pitched sound coming from the underside of the laptop (directly above the RAM slots). Sometimes its there and sometimes its not (mostly it is...). I found out that if i scroll down on a webpage the sound goes away...only to come back when im finished scrolling.
Any ideas?

Update.....I get my laptop back yesterday (friday) for the second time ..They said they replaced the HD with a Western digital HD because the toshiba ones seem to be having a vibration issue...Well, they put another Toshiba HD in it not the WD....The same Buzzing, staticy noise is still there and on top of it all the new HD make alot more clicking noise then the previous one....When I sent the laptop in for the second time, eveything was working fine except for the same Buzzing, staticty noise...Well Now i still get the noise and on top of all that, I can not turn off the LED lights on the keyboard which I was able to do before, I can not run any Toshiba software (IE PC Health, Eco...Etc) I get Bios errors and other errors, and some things are freezing....Spoke to them again, and now had to call the Case Manager,,and all they said is to send it back to their main repair place, not the repair depot.....I told them all i want is another new machine....getting tired going 1 month with out a laptop and all you guys are doing is guessing, replacing with out testing and sending it back and they said they can not replace it.........This is one for the books.....I should of bought the HP or Dell I saw first......to be continued.

High Pitched Sound and now the hanging

Hi
Since I bought my Mac, it has from time to time generated a high pitched sound (just soft enough to not drive me totally crazy).
Recently I noticed that this sometimes goes together with my machine hanging. As soon as the sound stops then the hanging stops. It does not always hang when there is a sound, but there is always a sound when it hangs.
Is this something I need to get checked out? or is there something I can do about it?
Please help

Hp 2310 monitor low volme high pitched sound - whining - low volume

My monitor makes a low volme high pitched sound
But only if I go above 1400 x 900 resolution.
Below that it is okay
2 years old.
Otherwise not a problem.
Brightness 45
Contrast 100
Backllight hours 12259

It's not totally unusual that as electronic circuits age a high pitch whine will develop depending on the monitor's settings. Additionally, some people's ears are more sensitive to higher frequencies. It happens.
======================
Is the monitor safe to use in the meantime while it whines? Sometimes I have to use the higher resolutions.
Right now, it is not a big deal. Since I use 1440x 900 and have it set to where there is no (or an imperceptible) whine [That can alter with brightness or contrast changes] , am I safe to use the monitor?
At 45 for brightness, and 100 for contrast, a 1440x900 resolution is okay - no noticeable noise.
Can safely run the monitor with the whine, on those occasions when I have to change the resolution.
At what point should I get a new monitor?
BTW: Changing Brightness and contrast can alter the whine, but what works for one resolution will not work for another.
So I leave the brightness and contrast alone, and tolerate the whine if I temporarily have to change resolutions for my graphics work.
Because if I reduce the whine on a higher resolution, it will screw up my 1440x900 resolution.
What causes this?

High pitched sound - something to do with internal microphone ??

Suddenly my Powerbook has started emitting a high pitched sound through its speakers. You know one of those high frequency ear-blowing sounds when a PA system is being set up and the mic is getting tested and the amp's turned up too loud?
I'm not sure exactly what I was doing when it started, but I think I was making or receiving a telephony call via iChat. During or just after the connection process (which didn't work for some reason but that could've been a problem at the other end), this high pitched squeal started. I can get rid of it by turning down the output volume - the squeal disappears but that of course turns all other output sound down as well. The sound disappears when the volume is turned down about half way.
But...even if the sound is turned down half way, if I put my hand over the left speaker, the sound comes back. No sound comes back if I place hand over right speaker. I assume then that the inbuilt microphone is under the left speaker area, and this has something to do with the inbuilt mic.
The only other thing that's happened in recent times is that I used this Powerbook's audio line-in port to record some sound from an audio casette recently. I used Audio Recorder 2.0 for this. I can't imagine this has been the cause, but thought I'd better mention it. If I go into the Sound Preference panel, I can stop the squeal by changing the sound input device from internal microphone to Line In.
Anyone have a clue as to why this is happening and how iit can be fixed?
Many thanks, Steven

Hey, great suggestion Burn. It prompted me to look at iChat preferences, since that was the only application that I've had open which might engage the internal microphone.
Within iChat Preferences, I clicked on the 'Video' icon, and for the 'Microphone' setting I saw that 'None selected' (or something like that - that option has gone now?) was in place. So I changed the setting to Internal Microphone. The whistle or screech was still there. Then I changed the setting to 'Line In'. No more screech!!
A good result, but is this the way it's supposed to be? Does having the setting as 'Line In' mean that I have to plug headphones in whenever I want to use iChat for internet telephony? Unless I manually change to Internal Microphone, but then I suffer screeching again?
Cheers, Steven

Macbook Pro and high-pitch sound, please help!

Hello,
     I have a Macbook Pro 13 inch that is almost brand new. I just got it 3 months ago for my birthday. About a month or two with my new computer I started hearing a high-pitch sound comming from the computer. The sound only lasts about 3-6 seconds and it goes of at random times. It might make the noise 5 times in one day but then it might go away for 3 days, totally random. The sound comes if the computer is sitting there or is being used. After about 3 months of this going off I deceided to bring it to the Apple store in New Haven, CT. Does anyone have the same problem?
     After bringing my computer in and telling them the problem, they tested in for about 30 minutes. Everything was fine. No fan problem or hardrive problem. I brought the computer back home and within 3 days the sound is back. I drove to the Apple store again told them my problem,again, and they did they same test with no results. Brought it back home, noise is still there. This time im starting to get angry, they arent offering any solution. I bring it back and they take it for about 48 hours and do a extensive check. Nothing was found. I bring it home again and the noise is still there. My father and I went to Apple pretty angry and told them that we appreciate the time they take but something really needs to be done. They have sent it out for 3-5 days and we are awating a phone call to see whats wrong.
     I am hoping that they find something or if they dont can they can replace my computer? I am not spending hours of my own time and gas money going back and forth to Apple for no reason..the Genius bar guys have been no help telling us basically that we are lying and that there is nothing wrong when clearly there is. What can I do? Has anyone had this same noise come from their computer? I really appreciat everyone that decideds to throw some input in. Thank you so much.
Notes:
I have the latest software
Macbook Pro 13'
No physical damage done

Make a recording of the sound so the next time you take it in you can let them hear it. It might be best to do a video of the unit so the sound is combined with pictures/video of the computer so they know the sound is coming from it.
IMHO the guys at the B-bars are just about useless for this type of thing. If it isn't a bad drive, HDD or DVD, and the system seems to run OK (actually even if it doesn't run OK but runs at all) they will say "Everything looks OK". Or if the thing is dead they can help. That help will be "You need a new HDD" "You need a new DVD drive" "You need a new Logic board" and that's about it.

Computer freezes, then a low-volume, high pitch sound

Hello there,
My trusty 2002 MDD is randomly freezing on me for the 1st time! Disk Warrior nor Disk Utility form external boot-ups detect anything wrong. Thus, it doesn't seem to be a hard drive issue. Memory status on System Profiler checks OK.
Once the beach ball appears I can't do anything but press the power button to shut it down. I've noticed that while frozen a very low-volume, high pitch sound can be heard. ???
Thanks a lot for any feedback that you may provide,
Jacobo

Hatter,
Thanks for the prompt reply. Like you proposed, I've started from my FW drive (not after a freeze though) and everything drive-related checks OK.
Yes, my video card (Radeon 9800) does have a fan. I've though about this and the PSU as well. The latter is the quieter, less powerful one.
My drives are less than a year old and seem to be OK.
I’ve run Applejack (w/ memory check) and all is good.
Can the Apple Diagnostic CD pinpoint any of these issues?
My MDD has been incredible when it comes to reliability. She has not given me ANY problems whatsoever while stressed to its limits.
Thanks again for your time,
Jacobo

When burning cd makes a high pitch sound

When burning a cd or dvd it starts to make a high pitched winning sound

Hello sirelosealot
It is nice to hear your opinion but I think it is not so objective. I have the same notebook model since 8 months and my AC adapter does not produce high pitched sound. It runs as expected. For me it sounds like defective AC adapter and I hope you will get one for free (warranty).
If Toshiba sell thousands of Satellite A210 can you imagine they do such mistake? I do not believe this? Every company has quality control and such mistakes are extremely rare and maybe it can happen by individual products.
I really do not understand that ASP can say something like this. Strange people!

A very high pitched sound @ startup

Hello and thanks in advance for any leads.
I had a very strange thing happen. At startup there appeared a VERY loud and high pitched sound just at the time menus began appearing on top of the desktop. At first I thought it was the smoke alarm! it was so loud. There has been no new updates or software installed (that I know of...).
It has happened a few times since, and the only common thing I've noticed is that it does this after I've moved my laptop while it's on. Say from the desk to the reading chair in my office (distance of 5ft maybe). If I shut it down at that point and restart later it would do it. I cannot repeat this issue, it's just that the few times it has happened that is the only commonalty.
Is my motherboard, HD, or sound card about to go?
Thanks!
Sabah

That's what I was thinking as well, that it is a Hardware issue. I have replaced the sound card on the Pismo about a year or so back, (though, I don't know why it would start acting up now)?
To answer your question, it is a continuous piercing sound (very loud, almost unbearable)!
Thanks JPL

High Pitch sound after inserting MAC OS x DVD on superdrive

When inserted the Mac OS x DVD to install Windows Drivers in bootCamp the drive started to make a high pitch sound (loud) while rotating on high speed. Is this normal?
I've tested with a DVD-R disk and didn't noticed any noise, but the disk rotates at a lower revolution in this case.
What Do you think about this? Should I return it?

If you have this model of G4 1.67 Powerbook:
http://www.everymac.com/systems/apple/powerbookg4/stats/powerbook_g4_1.67_15hr.html
Then 10.4.0 Server won't install. There will be drivers missing.
If your supplied restore disks are bad, then you need to get those replaced.
Simply don't use the Mighty Mouse during the install, there's no need.
When installing a stock 10.4 server overtop a system that comes with a newer OS, even if it's just 10.4.1, Apple has a very specific set of procedures you must follow
http://docs.info.apple.com/article.html?artnum=302960
The target-mode hint won't work for installing Mac OS X client (vs. Server) because your powerbook is a G4 and the Mini is Intel-based.
And there is no Universal Mac OS X client installer yet.
If your Server install is the 10.4.7 Universal Binary version, then it should be new enough to install onto your Powerbook, although it is not supported hardware. In which case you might be able to use the Target-mode tip suggested. It may or may not work.
Probably the only legal way for you to do this is to uninstall OS X Server from your mini first. You'll have to check with Apple on that one.
At the very least, if you are only using it on one machine then in spirit if not in letter, you might be fine.

High pitched sound emitting from brand new HDD?

Part 2 of my HDD woes.
I received my repaired laptop with a brand new HDD today on my MBP 4,1. This time around the brand is Toshiba, my last one was Hitachi and the one before that, I can't really remember. But the point is, with the last two hard drives I've had I've NEVER heard anything like this.
The hard drive is emitting an extremely loud, and annoying high pitch sound. At first, I thought it was my laptop when it was plugged in - unplugged it and lo and behold it's the hard drive. I put the computer to sleep, the sounds stops. When I open my laptop, that is how you can for sure tell it's the drive because the sound starts up with the hard drive. I actually have a headache from it, it is SO awful.
I'm extremely upset, this is my third hard drive in less than three years. I just wanted to know if anyone else experiences this, because I don't think this sound is ok at all. Is this typical of Toshiba HDD (250 GB)? I'm really hoping to read that someone else had this problem and that they replaced the drive for them. It's getting to be absolutely ridiculous, especially being in a professional program where I rely on my laptop everyday.
Advice would be wonderful, I'm sure this will mean I need to go back to the Apple Store again tomorrow.

Yep, called Apple Support this morning and I spoke with the Senior Advisor and he was very disappointed for me and was extremely apologetic that I will have to take the laptop back and get a new HDD. He assured me that they will give me a new HDD - again. Just frustrating because I already took the time to (2.5 hours!) to transfer all of my data from Time Machine to the new HDD.

Can loud tones, high pitched sounds, loud music and loud loudspeaker calls destroy iphone 5 speaker ?

Can loud tones, high pitched sounds, loud music and loud loudspeaker calls destroy iphone 5 speaker ?
TQ

sounds are air being moved
if exposed to a high enough sound being moved presured impuls then
any device could take damage
but your speaker which are maded to move sound and be moved by sound
would last longer then mostly anything else if your phone in terms of being damaged by sound
so the answer is yes
but not likely before anything else in your phone being destroied by the same loud music plus

G246HL high pitched sound

Hello all! I just bought 2x G246HL monitors and they are both up and running lovely, except that one of them is making a very high pitched sound when displaying the PCs output (it doesn't make this noise if it is just showing the Acer and Energy Star logos). I have tried adjusting brightness settings as that helped with my old monitor, and changed cables and inputs to see if that was the problem, but I'm not having any luck so far.I know that sound can often be capacitors, but I'm hoping there's a simple solution that one of you guys might know of, as this noise is quite irritating. Thanks in advance for any advice!

Hi Acer-Justin, thanks very much for your advice! I was all set to do just that when I received a suggestion to turn the brightness on the monitor's built-in menu up to max (and adjust brightness settings in OS to compensate) and this got rid of the sound immediately!

has the video been completely downloaded onto your MacBook Pro when you start to play it? Or are you playing it while it downloads, AKA streaming it?

White screen and high pitched sound whenever ipod is on

Anyone know how to fix this? Haven't used this ipod in a while so i charged it up to the max, but when i turn it on the screen remains white and a high pitched sound constantly rings until it is turned off. Tried restarting the ipod but i still get the same white screen. I even updated the software on my computer but no fixes yet...

Try connecting the ipod and resetting it while it is connected.
