Cracking strange sound when comming from sleep

When comming from a sleep (not always, but when beeing longer in sleep) I hear (next to the superdrive sound that is normal) a sort of cracking 'strange' sound out of my left/center area just around where the fan is.
It's a sound like you plugin a radio with an headplug let's say. Seems to come out of the speakers, but i'm not sure about that.
Is it normal (didn't do this before, only noticed it now after a month)? Or can i add another point to the list when i'm calling applecare (i really have a very monday morning machine i guess,: cpu whine, display not ok, strage blinking numlock sometimes).
Did find some thinks that look alike:

Great description...! I thought it sounded a bit like the trashcan sound.
I have got the same thing which isn't exactly my biggest problem... I also have the situation, that my MB doen't go to sleep, unless I directly tell it to. I thought the sound was related to that problem, but as none of you have mentioned it...?
Also my MB cannot be started normally every now and again and I have to do a PRAM reset to get it running again.
This is my second MB, so I'm slowly running out of patience...
The first one had the RSS, by the way.

Drive sound when waking from sleep?

Hi, I am getting a short 2-3 second drive sound when I wake my MBP from sleep. It sounds like it is checking to see if there is a disc in the drive or something. Also might be described as the sound when your first put a disc into the drive(but maybe shorter). Is this normal? And also if it is normal is there a way to stop it from making the noise because I actually find it annoying me, I wake my computer from sleep a lot throughout the day. My friends MBP who bought his just a few months before mine does not make a sound when waking from sleep. Thanks.

They all do. All of them. Yours. Mine. Your friend's. Old PowerBooks. Brand new MBPs. Everything in between.
My friends MBP who bought his just a few months before mine does not make a sound when waking from sleep.
Maybe his optical drive is broken?
Or, more likely, it's not waking up from sleep at all - Energy Saver settings can be used to set the display to sleep before the MBP sleeps - a key press will "wake" the display, but the MBP itself was not asleep, thus no noise from the drive when it the display is reactivated.

Rustling/Static-like sound when awakening from sleep?

It seems to be coming from the speaker, the left side I think, and it definitely isn't the sound of the drive spinning up.
Anyone know what this issue is, how to fix it, or if it is a sign of a more serious problem?

I've got the same issue, though I don't really worry about it - it's definitely coming from the speakers - when I awaken it from sleep I can hit the volume buttons and it'll get louder/softer. Unfortunately, I'm not sure why it does that - you're not alone, though it doesn't seem like a serious problem.

Play sound when awaking from sleep?

Hello! I'd like to make my Mac play a sound (.aif file) each time it awakes from sleep... any way to do this? How about playing a sound when starting up?
Thanks!

Hi, John.
1. SleepWatcher isn't a tool for Terminal newbies, but it's the only utility of its kind of which I am aware. My book focuses on troubleshooting — valuable on its own — but not programming: implementing tasks with utilities like SleepWatcher is clearly in the programming category and involves writing shell scripts or AppleScripts.
I don't do programming tutorials on the Discussions since they can become very time consuming and if you make errors, then we get into a long thread trying to resolve them, which can be very difficult using a vehicle like the Discussions. I try to focus my limited time here on helping people troubleshoot their Macs. For questions like your post, I try to point them in the right direction or give them steps that can be accomplished without programming. I'm sure you can appreciate that.
2. You wrote: "Also, I can add my file to the Login Items pane but it doesn't automatically play -- QT starts up, loads the file, but it doesn't play automatically..."I see you sorted that out. I suspect you did so by changing the default application for the sound file in question to QuickTime and have QuickTime preferences set to play movies automatically when opened.
With QuickTime Pro you can save any sound file as a .sfil file and use PlaySnd to play it via Method B in my prior post.
3. You wrote: "I've been a Mac user since 1984... it was easy then, your file just went in the Startup Items folder (that doesn't seen to have the same function anymore...)."It still does.
Whether something is placed in /Library/StartupItems or added to your account's Login Items depends on if it is a System-wide function that should be started for all users before any users log in (e.g. enable the process used by anti-virus solution), or execute when a specific user logs in, respectively.
The SleepWatcher case is different: you need to know how to program the specific action you want the Mac to perform when sleep is invoked using a shell script.
There are plenty of resources available to learn the Terminal and Shell Scripting.
- I recommend some books and other online resources in my "Learning About Mac OS X" FAQ.
- Once you've made some headway in learning Terminal, one can find a plethora of resources concerning shell scripting with this Google search.
- There are a variety of Developer-related Apple Discussions for asking coding questions concerning UNIX/Terminal, AppleScript, etc.
- You could always e-mail SleepWatcher's author (his e-mail address is at the bottom of his Web page) for advice.
Why not take up the challenge of learning Terminal and a bit about shell scripting? It can be fun as well as a valuable skill. We only grow by challenge!

Unusual sound when waking from sleep

To start off I have a black MacBook that I bought around March of 2006. Never had this problem before so I am a little concerned.
Okay to the issue, I woke my Mac up around 1:40pm today but instead of the usual wake up noise I got something else. It's the regular noise only it sounds a bit slower and lasts a second or two longer then it normally does. I wait a bit then I put my Mac back to sleep. After waiting 2 or 3 minutes I woke my mac back up with the same results. It wakes up fine, but it emits that unusual sound when waking up. I don't know if this is related or not but before waking the first time I did notice that my Mac was a little warn where the powercord attaches even though it had been off since about 3pm the day before and was located in a relatively cool room.
I also noticed when I put my ear up to my Mac that there is a weird buzzing sort of sound. It is continuous, but can only be heard if I put my ear up to the keyboard.
I'm wondering if something went bad on my Mac, since I have had it for about 3 years now with no prior issues other then heat issues.
Any help would be much appreciated.

The usual wake up noise you refer to is the optical drive spinning so as to check to see if there is a disc inserted in it.
Your Macbook should not be at all warm anywhere if it had been off for a few hours as you said. It should be room temperature if it was indeed shut down. Are you certain it was shut down?
I don't have any solutions to your problem, but just stating a couple points.
If it continues to do this try booting up into another User Account. Create a new account for this purpose. If it works good in a new, clean user account then the problem is in your main account. If the problem still persists in the new account try an Archive and Install with the install DVDs. If this does not cure it then the problem may well be hardware, but not for certain. But, this is the non-destructive, non-evasive way to go to start with solving the problem.

MacPro speaks strange phrase when waking from sleep

When my MP has been asleep for a while and I wake it up, it uses a very pleasant conversational voice to say "the referred store is supplied". At least that's what is sounds like. Speakable items are off. Universal access speech is off.
Mac Pro 2x 2.66 Dual-Core Xeon, 5 GB RAM, partitioned external drive - one partition for Time Machine and one for Carbon Copy Cloner.
I have Googled and searched the Mac forums and can only come up with those who have turned on speech stuff by mistake. This is not the case here.

I heard "the voice" again today and my wife said that it had spoken while she was using the MP. We discussed what it was saying and she said it sounded like "refurb". Snap - the light came on. I instantly launched the recently updated RefurbMe widget, flipped it to it's info screen and, as suspected, was a checked box for voice alerts. I'll chalk this up to stupidity on my part. At least I don't need to call an exorcist for my MP or a psychiatrist for myself.

Missing sound + missing USB power (sometimes) from Thunderbolt Display when waking from sleep

Hi
Two problems - one of which is driving med crazy!!
Have the latest updates, and the display is connected to a MBA (mid 2011).
The two are almost alwayes connected, and every time I wake the MBA from sleep, the Thunderbold Display does not "support usb sound" - the sound options are only MBA and headphones. Only a restart will give me the option to use Thunderbolt as sound output: WHAT TO DO!?!?!!
Sometimes when waking from sleep the USB in the Display seems to be "off" - the will not charge my devices (iPhone, iPad etc.). Only reboot seems to fix this... I have seen this in other discussions but not found a permanent solution - any thoughts?

Same here but reinstalling OSX is a bit drastic. I solved the problem by deleting a preference.
Go to Macintosh HD then System then Library then Preference panes then Sound.prefPane
Delete Sound.prefPane (you need to type your password).
Logout or restart.
This has happend twice this week so WHY is this suddenly occurring?
Hi,
I found this solution in the forum, but I can't find it again. I had cut and pasted it into a text file, because it solved my problem. I just don't want to take any credit for it. It did work for me. I had no problems for 3-4 weeks with the monitor, I have had the sound problem since last Friday. Very frustrating.

HT2844 My front headphone jack does not work when connecting a head phone to a new mac pro desktop computer. The sound still comes from the speakers. Any solutions?

The front headphone jack on my new mac pro desktop computer does not transmit sound when connecting a headphone or ear buds. The sound still comes from the speakers and is not redirected to the head phone. The port has never worked. Any solutions?

okay, try option-clicking on the speaker icon on the top of your screen. That should bring up a list of sound output options. including headphone. You could try messing around with Audio MIDI. It may be possible that the thing is still stuck inside the headphone jack. Careful use of a toothpick may get it unstuck. I dunno, I've never had a problem with the headphone jack. If all else fails, call Apple or take 'er in for an appointment

Noise when waking from sleep

I have a G4 iBook 1Ghz, 512MB Ram, 60 g HD, running 10.3.9. When waking from sleep, it has a loud buzzing noise that comes from the speakers. I know it is the speakers as you can silence it with the volume. If you restart, it is silent. It is silent from startup. It only does this on waking from sleep. At times it won't wake up at all, only responding to a forced restart. I've zapped the PRAM, reset the PMU, and all of the sound preferences. Anybody got any other suggestions?
Thanks, Andy Ford

I have this problem too. Sounds like shaking a can with some sand in it. Soft, not really noticeable unless you are in a quiet room or using headphones. Have all sound effects turned off in system preferences.... Have tried muting the volume. That doesn't work.
I also notice that I get the same sound if I do something that would otherwise generate a system error noise (like searching for a term in Safari that is not present on the web page). But only on the first instance. So on my initial search for the term, I get the soft noise. If I do Cmd-G to search again, no noise.
It's strange and I wish it would go away but I have been able to ignore it so far.

Strange behavior after waking from sleep

I recently got a Mac Pro 3.33GHz 6-core and put an OWC 60G SSD in as the boot drive. It worked great for the first month or so, but now it's acting strange. Before, when waking from sleep, my computer would immediately come on and be ready to use. Now when I wake it up, it takes a good 20 seconds for me to be able to use. (It's a very long time compared to my computer being awake before I could turn on the monitor.)
When waking, moving the mouse makes a stuttering motion and its not useable at all until my computer is done with whatever its doing. And, my external firewire drive always crashes like I didn't properly eject it. It never used to do this.
I've tried waking my computer without the drive on but it still acts the same. I haven't changed or installed anything since it has been doing this. Does anybody know what's going on? Thanks

Yes that is something I was thinking about mentioning which is called zapping the pram. It will reset some of your settings back to there defaults but no big deal and it does eat up your battery on your logic board so only do it when needed.
It may get rid of the problem.
as cscscs said.
while restarting, hold down option, command, P and R all together, which is supposed to do some kind of restore to hardware (I think)
Before you hit the power switch hold down the command option p and r keys then hit the power button and hold it down until you here the computer chime twice then let go.
I found apples instructions here.
Resetting PRAM and NVRAM
http://support.apple.com/kb/ht1379
1. Shut down the computer.
2. Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
3. Turn on the computer.
4. Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
5. Hold the keys down until the computer restarts and you hear the startup sound for the second time.
6. Release the keys.
the other bit he said about holding the boot button with everything unplugged I have not heard before but I would do it then zap the pram and see if your good to go.

Kernel panic when resuming from sleep

I've been getting random kernel panics on my MacBook Pro when resuming from sleep. That is, only when resuming from sleep - otherwise the computer is fine.
I read some other discussions on here regarding kernel panics, but it seems that an inspection of the panic.log file usually uncovered a bad USB driver or something of that nature. I have no extra peripherals on my machine, and the panic.log is fairly vanilla. In fact, every entry in the log looks like this:

Yes, every log entry ends with that "invalid frame pointer 0xbffff358" bit.
The only thing I can surmise is that the memory (factory installed) is faulty, given that the frame pointer address is always the same.
Can anyone shed some light on this i.e. does this sound like I'm on the right track?

AH HA ! Then yes the combo updater is a good first step. It's not the same as applying all the smaller updates as they come out, using this ensures that every aspect of the OS is current. Before and after you use it, Repair Permissions ...

IMac G5 Dies When Waking From Sleep

I have a Rev A iMac G5 I bought in 2004. Recently it started doing some weird stuff when waking from sleep. After looking at some of the other posts, I think this is going to be repetitive, but I thought I would see if anyone had any suggestions
After either putting the computer to sleep or letting it go to sleep, it will frequently die after the mouse has been clicked to wake it up. I have tried resetting both the SMU and PRAM as well as repairing disk permissions and repairing the disk. None of this has seemed to help. Occasionally, I get lucky and am able to wake it from sleep normally, but this doesn't happen often. After it dies following the mouse click, I can unplug it and then plug it back in and it will start up normally. Interestingly, it will start up from shutdown normally as well as restart normally. Additionally, as long as it doesn't go to sleep, I think you can typically use it as long as you want and it won't quit.
Today, I took the back cover off and messed around with it for awhile. The diagnostic LED behavior seems odd to me. LED #1 comes on when it is plugged into the outlet. When following Apple's instructions for troubleshooting a computer that won't start up, mine does fine because as I said it will start up normally if you unplug it and then plug it back in. Because of this, I set my computer to go to sleep quickly with inactivity. Although it did wake normally at least once, it died numerous times. The irregularity seems to occur with LED #2. One time it "died", I believe LED #2 actually remained lit and something seemed to still be working based on noise. However, the green light for the "caps lock" button wouldn't come on. Other times LED #2 would go out when it died after pushing the mouse with it asleep. During these times, I could push the internal power button and LED #2 would briefly light up, but nothing more than that would happen. On more than one occasion I would then push the SMU reset button and then push the internal power button again at which point LED #2 would fail to come on at all. After pushing the power button (and occasionally pushing the SMU button again) what seemed to be a random number of times, the computer would all the sudden start up normally again.
My top 3 guesses are a failed power supply, failed logic board, or exhausted PRAM battery (I have never changed it). The first two may be a bit to pricey for me to consider replacing. If they are the problem, I may just settle for setting the computer to never sleep. Does this sound like it could be caused by the PRAM battery going out?
Any advice would be greatly appreciated!

My bad on not reporting back sooner. Indeed, replacing the PRAM battery did not fix the problem. The situation seems odd to me as I was able to sometimes wake the computer from sleep without it quitting while others times it dies. It does fine as long as it doesn't go to sleep. I can start it up and shut it down with no problems; additionally, it appears to do fine even when left on for long periods of time as long as it doesn't go to sleep. To be correct it doesn't seem to so much be the state of "sleeping", but the act of trying to wake it up from sleep. I don't think ventilation is a problem.
What I have done is just set it to not sleep. We just shut it down once in awhile. Rather than forking out the money, I think I will just use this work around as long as it continues to work.
