Loud rattling sound from the back of my MacBook?

It doesn't sound healthy...
I don't remember what it sounded like before this sound started - But that just proves that I haven't had this sound since I bought it.
It's like a constant rattle (quiet) like something's loose... And then there's a quieter hummmmmmmm from the fan..
If I turn the laptop upside down (so keys are facing the floor) it stops!
Could it be a loose part? Or is it supposed to sound like that? (My first Mac)
Thanks.

I fixed it... by hitting the bottom quite firmly.
But I'll ring Apple Care next week if the problem comes back!
Thanks

A weird ticking sound from the base of my macbook pro?

My macbook pro was bought in October 2011 but I think it's the Early 2011 edition. It's an 15 inch. My problem is that I hear a weird ticking noise coming from the base of the computer. It sounds like it is coming from under the keyboard and the mouse pad. I usually hear it whenever I move it around or place my hands on the hand rest spot(?) when I'm typing. Anybody know if I should be worried or how to fix it? The sound is really annoying... Let it be known that I baby my macbook pro. I have never dropped it on the floor or slammed it on a table or something.
Thank you in advance
P.S. If it matters, I'm running on
Mac OS X Lion 10.7.2.

That could be the stepping motor in the hard drive making noise. Sometimes the noise means nothing, other times it could mean a problem with the hard drive and it could fail soon. Could be a fan out of allignment. If you can backup your data, do so. If you an get to an Apple genius bar, take it in and have the techs run some tests to find out what the noise is.

HP 2509m 25" emitting a strange fuzzy buzzing noise from the back

Hi, i've had this monitor for just over a year now, so far everything has been great, no complaints at all. Untill recently, the monitor makes a weird buzzing, fuzzy sound from the back. I dont use the oboard speakers as my main audio, i have after market speakers. When i power off the monitor the sound goes away. Does anyone know how to fix this problem ? Do i have to take it in to a repair shop ?

Did you bother to read my post above and click on the LINK in it???

All of a sudden loud sound from the right

All of a sudden my macBook Pro is making a loud sound from the right which I think is the fan? It happens when I first turn it on so it is not too hot.
I'm concerned because my last ibook g4 had a dead hard drive in less than a year..this sound is somewhat similar to the clicking hard drive, but forgive my ignorance the hard drive is not on the right?
Is this a normal new sound? Does feel that way.
cursed with macs.

MissWit,
Its the fan, you got two one in each side.
I have same problem, but mine often appears when the MBP is warm or let me say been running for a while, at the same time I feel vibrations when I touch the casing or maybe housing is a better word, well the aluminium cover...
I am 99.9% sure the hard drive is located to the left.

After iOS 8, no sound when playing video taken from the back camera..

How can I remove the background sound from the headphone jack for my MacBoo

for my MacBook Air problem adding music intensifier (Panasonic ST-HT1000) to give it an unpleasant sound background that sounds like a whiz, it's not so loud, but it is an unpleasant .. after a short time can get used to, but the fizz does not pass, however, believe that it is a big problem.
Further I notice that when MacBookAir disconnected from the charger, it remains quieter sound.
At first thought that the headphone jack (3.5 mm Headphone:
Connection: 1/8-Inch Jack) or wiere have problem, but tried 3 different cables, but that does change enything, the problem remains.
When I added iPhonu3GS playing - the background sound were not, then everything is OK!

There is no way to bring that up unless you have it typed in a document. You can use My Support Profile to find a list of serial numbers that have been purchased or registered with your Apple ID.

Recording sound from the PC

I am currently running a mixer into the front audio input jack on my PC, and have all external stuff (mic, mini disk, etc) coming through that.
Am I able to set up audition so that it can also record sound from the PC. For example, if I want to grab audio from a you tube video, or have an online voice chat or something enabled, can I open audition and record it? I have tried, but not been successful. My only idea is having to run the audio out of the PC, into a channel in the mixer, and then back into the PC with everything else.
Any help?

Capturing sound from the soundcard

Hello,
Does Audition make it possible to capture the sound from the sound card?
I don't want to record a sound using a microphone, I want to save the sound which is played on the sound card.
Regards

Assumption: You are trying to record using the internal sound card in your computer.
Right click on the speaker in the task bar (normally lower right of the screen).
Select "Open Volume Control".
In the "Volume Control" application in the menu select "Properties" from the "Options" menu.
Click on the "Recording" radio button and hit "OK".
This will bring you to the "Recording Control" dialog box. Check the
"Stereo Mix" radio button.
On most computers this will change input for Audition v3 to listen to the output of the sound card.
Note1: Make sure you are using "ASIO4ALL" or "Audition 3.0 Windows Sound" or you won't hear or record anything because two applications can't use most standard ASIO sound drivers at the same time.
Note2: Make sure you change it back to "Microphone" or you won't be able to record using the computers internal sound card.

SB Audigy 2 ZS Platinum - no headphone sound from the front pan

Hi all,
I had replaced my old broken Asus Mobo with the same type. After all hardware was reconnected to the new mobo I have noticed the front pannel headphone output doesnt work.
I have connected the card and the panel with the proper cable, the pannel seems to be powered OK. I even connected the card and the panel with the internal firewire cable.
The only difference is I have this time installed the drivers from the Creative website, whilst I used the bundled CD with previous installation.
Would that prevent me from hearing the sound from the headphones?
Will appreciate your suggestions,
Greg

Hey Ridenthatide,
?
I have the same problem as you. My system is MSI 865 PE motherboard and XP Pro SP3 with Audigy 2 ZS. I have reinstalled my system numerous times before and never had any problem, until this time....
?
- Format HD, install win XP, install SP3. Install Audigy 2 ZS driver and application from CD. Sound works.
- Install card's latest driver downloaded from Creative. NO SOUND!
- Device Manager shows everything ok. But control panel -> 'sound and audio devices property' has the device volume bar grayed out. Looks like system doesn?t recognize the card somehow.
- Install the latest application (organizer and other stuff), to no avail.
?
I tried to move the card to a different slot. After bootup, windows recognized new hardware installed, and started installing driver (I chose 'let windows auto search'). And sound came back. But if I re-install the latest driver again, the sound will go away.
?
I don't think moving card to a different PCI slot is an legitimate way of solving the problem, and problem still exists after the move. This has been really frustrating.

My imac froze. I turned it off & on from the back

my imac froze. I turned it off & on from the back. then I got a message that some of the files got damaged and it moved them so some other folder. Now, i think i have all my music but I can't find my apps. plus, all my podacts & some TV shows are under music & i don't know how to move them to thier proper places
Please help

I had this issue with my iPad 4. I rebooted the iPad holding down the two "start buttons," which is the home bottom on the bottom and power button on the top right, in the portrait position. Also check to see if you muted the iPad in settings or just turned down the sound all the way, or some other setting in "Sounds." I know that may sound stupid but it's an easy fix I'd that's the problem. I'm not an expert at all but I hope this helps. I'm actually having an issue with my update. It asked for a code after the update. Now I have to use it every time and can't get rid of it. Hopefully somebody will read my post!

How do I mute the sound from the video camera when burning a DVD

Hi there. I'm a new user of Elements 8. I have compiled some clips and added a soundtrack to the movie, When you preview the file you don't hear the sound from the video camera but when I burn it to a DVD you still hear the video background. How do I burn the DVD without the background sound from the video camera? On the DVD I only want to hear the soundtrack I added.
Thank you,
Doug

Thanks guys. Both options worked. Dowside to deleting audio (option I went with) appears to be that you lose the audio forever. So if I ever wanted to bring the audio back I wouldn't be able to.
You are partially correct in that the Audio is no longer on your Timeline. It is still in your Project Panel, and you can move it back to your Timeline if ever needed. The complete removal from the Timeline is why I work with the Audio Mixer in cases like this. Also, on could alter the Gain on a Clip by Clip basis.
With using the audio mixer it appeared I had to mute each clip separately. When I highlighted all the clips and selected mute for audio 1 it wouldn't mute all of the selected clips.
The Audio Mixer works at the Track-level, and not at the Clip-level. That is why I use it so often - one click, or slider adjustment affects the entire chosen Track. If it did not work at a Track-level for you, something is wrong. Now, if one has Clips on different Tracks, then Muting of all of those would be required, or one would have address things on a Clip-level basis.
Any way to use the audio mixer to mute the clips in mass?
See above for how it should work, and also the exceptions - Audio on several Audio Tracks.
Good luck, and remember that your Audio still resides in the Project Panel, should you ever need it again.

Hi,
Sorry I misunderstood, central (center) speaker is the one sit at the middle, we normally call Left, Right and Center speakers. Anyway, what is your speaker icon (bottom right corner) says ? Does it look like this ?
1. If NO, double click it & turn it ON
2. If YES, right click it, select "Playback devices" and turn it ON, it should look like this:
3. Otherwise, please post back

I only get sound from the computer's speakers even though I put in headphones

I have for a while now had the problem that I only get sound from the computer's speakers even though i plug in the headphones, I have rebooted the computer but still the same problem occurs. So i thought there might be someting wrong in the settings, when i open the soundsettings and plug in my headphones nothing happens, usually I believe there should be a text appearing that says that the sound is now going to headphones, am I right? any how, it still just sends the sound out to the speakers and there is no option to send it else where then "soundflower 2ch and soundflower 16ch".
I do have an external sound card, for music recording, that goes through USB, and when i plug that in i get the option to send the sound to that device and also to recive sound and i can also choose if i want to sent it to the computer's speakers. So could it be someting wrong with the headphone jack?

Good day!
Thank you for writing to the Dell Community Forum.
Boot into the System Bios and make sure that Onboard Devices- Integrated Audio is On. Then exit the System Bios saving the change. Once back into Windows, open the Device Manager and make sure that ADI1983 HDA appears under Sound devices. Then re-test the rear green audio jack #4 using headphones. Also, reply to this post with the service tag of the system sent via private message so that I can look into the details of the system and assist you better.
Have a great day ahead.

My laptop is making weird noices from the back and i wanted to know if its normal or not

Hello,
I bought my laptop not to long ago and weird noices is coming oout from the back and I wanted to know if its normal for it to make those noices

Weird noise coming from the back of the computer is not normal.
Humming noise from fans and sounds from working HD are normal.
You can take the computer to the Apple store and have it checked out.
Best.
