Very bad sounding noise.

Today I turned my computer on and was greeted with a very bad-sounding noise coming from the top-left of the computer, right under the escape key. It sounds like a motor running, but i've never heard it before. Just to clarify, this is a macbook pro with the click button.

Go to this apple website:
https://selfsolve.apple.com/GetWarranty.do
and put in your serial number.
To get your serial number click the apple in the top left corner of the menubar. then click about this mac. Then click the button that says more info. your serial number should be listed there!
FYI - that definitely sounds like a bad fan, Ive had the same problem before!
Hope this helps.

VERY BAD SOUND: MacBook Pro (unibody) with external JBL Creature speakers

Recently I've bought myself a brand new Mac Book Pro. I'm very happy with my new laptop, but I can't say that about the audio-output quality my new MacBook Pro delivers in combination with my existing external JBL Creature speaker set. In the recent past this speaker set was attached to my old iMac 17" flat, which delivered supreme music quality, but now in combination with my by far more superiour new MacBook Pro, the music sounds very disturbed with a background noise and it seems that the speakers do get to much power/signal - but still the music sounds very far away and the more I pump the volume the worse gets the music output (i.e. more noise is coming out of the speaker) and the right channel seems to have less power (or output). Now I've disconnected my JBL Creature speakers set as from time to time also static ticks are loudly to be heard when just connected whilst I don't do anything with my MacBook Pro.
Can anyone tell me whether this is a problem of the audio-design of the new MacBook Pro (aluminium unibody) and if so is there a solution for to by-pass or overcome this very annoying problem.
Many thanks in advance for your support!

It is true that the audio quality is a total crap, the audio card seems to be "Realtek" and yes it is ****, I am really ****** cause it is not a cheap computer and I have always used mac too and I am really disapointed. I just can't believe that Apple has passed by the audio quality that is so carefully observed in the ipod products. I have been blessed (no, it is really a curse) with a very sensitive unhuman high frequency hearing and my ears really hurt when I use the earphones with the Macbook notPro and I use it at low volume. You can even hear when the sound system goes off when no sound is played for a little while and the when a sound is played goes on and the noise begins. Also you can hear strange whistles and sissings wich are not continuous but the main amp noise is there. This kind of noise is produced by bad quality, low eficiency amplifiers or other factors I do not know. But I have tested several realtek integrated cards and the all are pure crap or less than crap.
Ok bye, bye.

My ipod records video with very, VERY bad sound

Everything else works just fine. I've tried reseting the ipod, but nothing happened.
The exact problem is that I can record the video, but, for example, when I talk, no matter how loud I do it, I can't hear myself on the recording. The sound is "weak".It sounds as if I were talking from a very long distance ....
PLEASE HELP ME, I really love this ipod, it's my favorite nano an everything else work perfectly, thanks .

It's an iPod touch 4g if that helps any

Very Very Bad Sound Coming from Quad at Start-Up

I've been a happy quad user for over a month and this morning I awoke my quad and heard a super loud "snap" like a serious electrical spark - scared the
$%@# out of me and my GF came running in when she heard it.
I find the quad always makes a loud "click" upon start-up, but this was atypical, I don't like loud electrical sounds emanating from my computer!
Anyone else hear this or have this problem?

thanks for your responses ... the loud electrical "snap" I heard was an isolated event and extremely loud - I jumped about 10 feet and I hadn't even had a coffee yet. There is a "click" sound upon hitting the power button which I assume is normal.

When I phone people can hear me without any problem, but I hear very very bad. The sounds is metallic and it is very difficult to understand. Have anyone idea of what is it about. I guess is not a software problem but I am not an expert. Thanks in advance

i have mainstage 3 installed and works 1oo% when connected to the battery, but when connecting to the mains for charging the program crashes. sounds do not obey. is one, even very bad horrible latency.
and I need to work on music not only in time but the battery after that.
I ask for help please

Thanks for the swift reply, I have been looking online and a loose plug seems to be somewhat of an issue with many, I hope mine is actually a problem and not what others are experiencing. It's taken me this long to even reach out for the simple fact I HATE being a complainer but this is just horrible.
Do you have an iPad 3 as well? And is yours not experiencing any issues close to mine?
Thanks again!

Is it possible to get a refund if i bought an album with extremely bad sound quality?

As asked in the title, is it possible to get a refund if i bought an album with extremely bad sound quality?
I am very unsatisfied with my latest purchase of the album "Never take ffriendship personal" by "Anberlin" ...

Bad sound in my x-fi audio after windows upd

I have accidentally downloaded this @ windows update on tuesday?
Creative - Sound - Creative X-Fi Audio Processor (WDM)Creative Sound sofware update released in June, 2007?
After that all my sound options were gone and i have a terrible bad sound.
Is there anyone who can help me to solve is this problem?
I am running win xp

If you need to remove entries from the registry it's not as bad as some people make it to be. You do have to be very careful because it can disable your system. First go to the Device Manager and uninstall your sound card. Go to Start Menu and click on RUN, enter "regedit" and hit OK. Click on the + tabs by My Computer then HKEY_LOCAL_MACHINE.
Make?a backup copy?by going to the FILE tab at the top and select the Export option. Name the file HKEY_LOCAL_MACHINE and save?it to your desktop. You can use this file to restore your registry to?it's original state?if needed.
Now click SYSTEM and then CurrentControlSet then click on and highlight Services. Go back to the top?and under the Edit tab select Find. Enter "Creative" in the box and then click on the Find Next tab. This will find any reference to the word Creative. Any time you find a reference delete the folder that the reference exists in. Go back up to the Edit tab after each time you delete a folder and click the Find Next tab and it will search for the next reference. Do this until you find all references in the Services folder. This should remove all the drivers for your Creative sound card but will also remove any drivers for ALL Creative products on your computer. If you only have the sound card this won't be a problem. Close the Registry Editor and restart you computer. You should be able to reinstall your card with the original CD or the driver of your choice. If you don't use the CD you'll have to tell Windows where to find the drivers. Restart your system a couple of times to make sure all your services load and it runs as it should. When your satisfied that all is Ok you can delete the file you saved to your desktop. ?Just be very careful what you delete and you will be OK. If this doesn't work you may have to format the hard dri've and start from scratch. Good luck.

T400: Very bad experience

I really don't know where to start, I have had so many problems with the T400 from the past one month! So, let me start at the beginning:
PC Config: WinXP, P8600, 4 GB Ram, 160 GB/7200 RPM, ATI 3470 card.
1. I got the the PC the 2nd of October. Out of the box, the computer was slow, much slower then my one year old Dell Vostro (1.6 core2duo, 160 GB/5400 RPM, 2 GB RAM, Win XP). The Vostro trumped the T400 both in boot time and regular usage.
2. I then started having issues with the display. Started getting weird lines on the screen. The speakers were making a screeching sound and there were some issues with the microphone as well. Called up Lenovo tech support and sent the PC to the service center. To top it off, I had a very bad keyboard with abnormal amounts of Flex and a displaced thinklight which was illuminating me rather than the keyboard.
3. The folks at the service center replaced the system board and also said they fixed the speakers.
4. I got the computer back and I continued having issues with sound. Sometimes, it doesn't play. And when it does, it has that screeching sound again. The PC was incredibly slow too. No improvements in the booting speed or speed during regular use. The didn't fix the computer back properly and everything from the plastic around the display to the case around the over the media card was loose. I could make out they hadn't put it back properly and I would press it in and it would come out. Moreover, the computer started hibernating all of a sudden. It is so irritating when you are in the middle of a presentation and all of the sudden the computer goes off. I had to restart it constantly. It also hibernates suddenly when I start up the computer from hibernation mode. I enter the windows password and once I'm in windows, the PC hibernates.
5. I called up technical support and told them all these issues. They said I can send it back in again for repair. I told 'em I would rather want the PC replaced rather than send it to repair again since I may have start having issues with it again. After 8 factory restorations, moving 100 GB data around each time and installing all applications again, I was fed up.
6. They agreed to replace the PC and I got the new computer today i.e.., 4th Nov '08. This is where things get interesting. The computer started up normally and I got the initial settings configured. Once I got into windows, the first thing I did was restart the computer. As it was booting, it froze at the XP loading page. I restarted the computer via the power button, and the same thing happened. I continued restarting for another 3 times with the same result. So, assuming a bad OS installation, I went ahead and did a clean install through thinkvantage. As the installation was going through, at some point of time, the PC restarted and got stuck at the same XP screen again. I restarted it a couple of times until, fortunately it went through. It then started installing applications and for some reason, it restarted and again got stuck at the XP loading screen. As of now, it is stuck there and won't go through.
7. I got on the phone with tech support and the only thing they could do was to send it to the service center.
A brand new computer right out of the box is heading to the service center. It doesn't feel like a new computer any more the moment it goes to the service center. I'm utterly and totally disappointed with the way Lenovo is building these computers. If this is the case, I might as well take my business elsewhere.
I don't know if I'm the only person out here with such problems or if there are any one else. And, I apologise for such a long post.. Please tell what I can do now. I don't want to go through the same headache again.

If it was 'really dark/ clear' then why sales guy was offering me a contract with a phone? Also, he said everything is clear from their side when I said I am interested in the best buy offer. This is very bad when you are ready to sell on your contract, but don't allow customers to buy from others.
Just wanted to let you know this 'customer service' as I spent more than half day in long waiting at both best buy and verizon shops... I thought I would get some solutions... Anyway, I moved on...

Very bad microphone quality with LCCS on Android

Hello,
I have created two applications with LCCS (audio and video conferencing), one for Windows and one for Android devices.
From my PC, all work very well. When I speak with my desktop microphone, the sound delivered to my phone is good.
But, when I speak with my phone, the sound delivered to my PC is very bad.
Maybe LCCS doesn't configure mobile microphone correctly ?
By the way, on mobile Microphone.getEnhancedMicrophone returns null and falls back to getMicrophone instead.
Any idea ?

OK I found that SPEEX codec result on Android (and maybe on iOS) is very bad when streamed. If I use instead the old NELLYMOSER codec, the result seems to be correct. Not fantastic, but correct.
I thought that SPEEX codec was fully supported and very good on Android... Am I wrong ?
Is there somebody here who try to use SPEEX codec on mobile ?

6120 Camera Results (very bad)

hey... i've just bought 6120 Classic...
it takes pictures good in daylight but very bad in low light (even light behind the camera)... i see alot of green lines (noise) on screen n in the picture
it says on the lable underneath battery 'Nokia 6120 C1'... wht does that mean? should i claim the warranty? n further y 6120 has no update yet where as my brother has 5300 n he has updated it once...
please help me wid this problem... i'm very disappointed wid this kind of camera result... thanks!

Yes it's very bad in low light, it tries to make it brighter by pixelating the whole image by green and red pixels.
I think you mean Nokia 6120C-1?
It's the type of 6120c i think.
Like the N95, It has three types, N95-1 (Normal version), N95-2 (Black 8GB version) and N95-3 (the Amercian version).

When i transfer an photoshop image in Indesign, this one come out in very bad quality and pixelise even once print

Hello,
I have an issu, every image i bring or change trough Photoshop CS6 and transfer to Indesign CS6 or Illustrator CS6 comes out in very bad quality and very pixelated whyle printed.
The original image in photoshop is 29x32 cm with 300 ppp.
When i transfer in Indesign, i have to reduce the site via the adjustment button and it comes in terrible quality.
It never happen before, its just recently, and i didn't change my way to save or the properties of my Photoshop, so if someone can help me to resolve this problem, i will be glad.
Regards,
Marie

Before I should save the image as a PSD (without Clipping Mask and dont flatten the image). the print would come out different colours...not the same.
Are you saying the printer can't get a .PSD to output, or a PSD's color is unpredictable? Sounds like your printer can print .PSDs, but you have a color management problem. By different colors do you mean that the printed CMYK color values are different than what was in the placed PSD? If that's the case it may be that the PSD had a profile that conflicted with the InDesign document profile and you are getting unexpected color conversions somewhere in the workflow.

Very bad sounding noise.
