Intel Mac :: It Has No More Sound After A Power Outage?
May 20, 2012
My iMac has no more sound after a power outage. I fear the soundchip is fried. I've tried all things like reparing permissions and verifying disk. I've read something about PRAM resetting?
This is now the 4th time this has happened, but this time I have at least what I believe to be a cause. After a power outage of about 30 seconds this past thursday all of my printers attached to my imac have disappeared. Not only this, but when attempting to even press cmd p from any program that I could possibly print from slows down the system to a crawl, and eventually crashes. When going through system preferences the printers menu takes about 10 minutes even come up, and when it does, it's empty. When attempting to add a printer back the system once again slows to a halt eventually not responding. I've tried restarting multiple times, making a new user account (which worked for about 3 months the previous incident happened.) The only thing that has fully fixed this problem in the past was to re image the computer. Â
My 2007 intel imac lost power a while back and has been slow and somewhat erratic since that happened. My area suffered a power interuption that lasted a couple of minutes. When i turned the machine on the next day I used the disk utility to verify the disk and repaired permissions. the disk was fine but there were some permission errors which were repaired.After doing all that I found Finder could no longer search and find files, I could still access a file normaly but I could not search for a specific file or a group of files 9 .dmg for example)Firefox was very slow to fully load (30 seconds), one loaded the internet access was fine - 20 mbs or so. I downloaded the latest version of Firefox but it did no good.I had loaded Enequeue a week before the failure occured and that stopped woking. When i would click on a song in my library it would just hang.console error msg indicated the library had changed.A remote printer that had worked fine before the event was no longer reachable. I can see the printer but I can't print to it and if I try to modify the printer settings in CUPS I have to reload the printer driver on the remote machine (a 27" 2011 Imac) because that computer shows the printer as being paused.
All of this seems like it's either a permissions problem or a corrupt system file. I've done the following ton try and fix it Used Disk utility to verify the diskUse disk utility to repair disk permissionsDone a safe mode startReset all the plists.This older imac is used mostly to access my music files on the new Imac, I then use the optical audio output to feed an outboard DAC attached to me stereo in the living room. The new imac is backed up daily but this one is not because it really doesn't have any data on it. It seems that i should be able to fix this without reinstalling everything. Both machines are running OSX 10.6.8.Is there anything else i can try or should i just reformat the disk and reinstall OSX?
My power went out while I was using my iMac today. I was wondering if this could have caused any damage to the computer and if I have to run any utilities etc to investigate?
I'm currently out of the country doing field research and just the other night, there was a power outage here and now my ibook won't start up. Of course, being in a "third world" country, I wasn't able to invest in a good power surage protector.
Is my computer dead for good?
I have a lot of work that needs to be done and my computer is essential here. Anyway, I can rescue my computer? I press the power button and it does absolutely nothing.
What do you people think might be the problem and how much am I looking at to fix this?
well i've had my mac for about 5 months now, its a OS X 10.5.8 2.4 GHz Intel Core 2 Duo 2 GB 1067MHz DDR3. I have an AX and it has worked flawlessly until about an hour ago. The power in my barracks went out, (im a Marine by the way) and all of a sudden i can't connect. I've tried resetting everything (i.e. the AX, the internet, and my mac) many times and nothing has worked. I've restarted my computer, the light is green on the AX, and my mac says im connected, but i can't get to the internet.
I put my i5 to sleep around midday, came home from work @ 4, and my iMac would not respond to keyboard, mouse, or power button mashing. My wife noted the power had gone out upon seeing the microwave clock. I checked the outlet (her Macbook was plugged into the other receptacle), and there's still power going to my machine.
My computer temporarily shutdown after a power outage. Something I was downloading on vuze went from 50% complete down to 0%. I presume vuze has lost it due to the crash. Any ideas on how I can get it to 'remember' again?
Yesterday evening there was a little lightening here abouts and the whole town lost power for around seven hours (I do not believe my home was struck, just the utility.) Upon manual restart, the date and time on my eMac had reverted to I think December 1977. Odd, because the PRAM battery is less than a year old, and they generally last me three to five years. Also now, when I start up my eMac, Airport asks me to choose a network to join and then asks me to enter a pass word. The Network Preference remains checked, "Remember any network this computer has joined." What ever could have happened, and how do I fix this?
my G5 was in sleep mode during 2 power outages. She will not turn back on, have tried unplgging, wait then replugging and turning powerstrip back on. Also tried holding down command,option, p & r keys along w/ powerbutton..I'm on my kindle fire rt now, but definitely need my Mac back up.
1- I have a Mac mini server running in the basement on a flat screen TV, I use this as my home enertainment center. There are Apple TVs on the rest of the TV's in the house and I have home sharing onÂ
2- thunder storms have caused a power outageÂ
3- The library has been cleaned. The items i still had for down load are still down loading, but all my movies, songs, apps, ect are not listed. Â
4- I was always going to get around to backing it up, and didn't. Iknow, I knowÂ
I think all the items are still there, I tunes just can't find them. One of the two hard drives was approaching full and i was looking at relocating the itunes files to the second hard drive, BUT being a novice with computers I was stumbling and never got it done. I had looked into it and remember scrolling through the screens that had been listed in forums. How do i search for Itunes files? the program runs, but the data is not there?How do i teach Itunes to look where i dropped the files when and if i find them? Â

I rebooted after a power outage, which switched off my mac. Booting up it took a long time, maybe 30Â min. Since then every task takes a very long time eg. to open mail 3 min. I got disk utility to open, my boot drive comes up in red, I still havent got any info on it.
Will this have done any damage? The macbook pro was not powered up, but I had the the mac ac adapter plugged into a power strip with the magsafe adapter connected to the laptop, since I keep it plugged into ac all the time at my desk. The power strip was on while the power outage happened. I had the 3 prong extender cord of the magsafe plugged into the power strip. The power outage was due to a problem with some power lines in my neighborhood, not from a surge of overuse of fuses in my home, so my whole block was without power for about 2 hours.I did notice the power strip has always had 2 lights on; one red, not protected, & one green, grounded. The outlets in my room are only 2 prong, so I have a 2 to 3 prong adapter plugged into the wall that the power strip plugs into. I know this is not the best, but my house is a 1950's era house, & I do not have the knowledge & have safety concerns about trying to convert my bedroom outlets to 3 prong. I hope this did not cause damage to my macbook pro. Is there anything I need to do before powering the mac on to use the next time? besides convert my 2 prong outlet to 3 prong? will there be any static charge? this outage happened on a very hot & dry day in my area.
When I power up my iMac, I encountered a very loud fan sound in the background that I had never encountered before.This happens despite turning off and powering up again.
I have a mac OS 10.3.5, PowerPC G5. The sound does not work. I have restarted the computer, played with sound settings, made sure all speakers and headphones are unplugged. When speakers or headphones are plugged in the volume works fine, but when they are not in, I can't hear the thing.
At first glance, this seemed to be an application problem, but two different applications that do similar things are effected by it, so I'm guessing it's more my Mac than the utilities. I have a 5.1 speaker system attached to my G5 via digital out. Switching between internal and external speakers is a PITA (go to System Preferences, etc.). I'd come across Rogue Amoeba's SoundSource, allowing me to switch right from the menu, and all was well. Until it wasn't.
After working just fine for a long while, it suddenly stopped. No explanation--selecting Digital Out didn't switch anything. Tried different things, including a complete uninstall and reinstall of the app, nothing. Ditto after going from 10.4-->10.5. Figured it was one of those things and gave up. Found an alternative utility: PTHVolume, which does something similar, but in different ways. It doesn't even SEE the Digital Out. The Mac OS X Sound Preference Pane works fine, though. What could be wrong that third party apps don't work with the Digital Out?
I've reset the PRAM (because of a totally different issue, actually) but that didn't change anything. Run Diskwarrior to no effect. Repaired permissions, nada. Deleted com.apple.soundpref.plist, no result. Deleted com.apple.audio.DeviceSettings.plist and com.apple.audio.SystemSettings.plist and that made the Sound preference pane disappear, necessitating a reinstall of 10.5 (but other than that, it didn't do anything).

I can't get any sound out of my G5. I've checked all my settings, and they're correct (I believe). I have a Texas Instruments built in sound card (TAS3004). I bought the machine a year ago used (it was a demo) and it's never had sound since I set it up.

We just updated our G5s here at the lab (QuickTime and Garageband ), and now the sound output is extremely distorted and crackly regardless if its a video on cnn or a song off iTunes. Tried Zapping the PRAM and repairing permissions, even reinstalled QT from the standalone installer on apple to no avail.
I have found that by plugging in my Apogee Duet firewire audio interface and ONLY WHEN AppleFWAudio was loaded there was a 10c CPU raise that was making my MBP (late 2008) hot!I wanted to monitor the power that was required for Duet to run and to see if the temperature rise was due to that, so:With Apogee drivers uninstalled (just to be sure its not their drivers related, which is notMBP on battery power with System Profiler opened (to monitor the mA required by the computer from System Profiler -> Power)
I Have a power mac G5 2.7 (early 2005?) liquid cooled. It has a ticking sound (like a clock), low level but still audible, can it be turned off? What is it?

I have an early 05 PowerMac Dual 2.3 machine that's making some intermittent clicking noises over the last few months. There's no pattern - sometimes it happens every few minutes, sometimes it won't happen for hours. The clicking sound is loud - and is accompanied by, what I can only describe as, a bit of a buzz sound. At first I thought it could be my HDD or superdrive, but I think the click is way too loud. Now the question - is this my power supply getting ready to give? The machine does not fall in the range of the power supply repair program. I'm already in the process of adding a second HDD to clone my main drive just in case.
For a while now, I've been getting a strange whine out of my mbp core duo right above the power button. I don't believe it's the common "whine" others have complained about as I've tried brightening the screen/turning on the camera. Tapping on the case will stop the sound for a bit, but it soon returns. The sound comes and goes, but in incredibly irritating.
I have a sample here. You may need to turn up the volume to hear it. Yesterday I replaced the right side fan, but the sound is back. Now I'm thinking it's the speaker, but don't want to spend more money on parts unless I'm relatively confident of the problem.
I have logitech speakers set up with my MacPro, and there is a steady stream of static noise coming from the computer. It's not the speakers because I have tested them with another device. It's definitely coming from my desktop. The strange thing is that if I restart my machine it goes away for a bit. But it starts back up as I open programs, browse the web, etc.

So my second power adapter for my Powerbook is dead (it replaced the original via applecare). I have had problems with it and even have tripped on the cord while plugged in thereby probably damaging it. I have heard the usual sparking sounds and have recently saw the blue spark ignite from the plug while out of the powerbook and in order to get green/orange connection light I've had to twist the plug until it lights up. After reading other people's problems I decided to look at the plug and noticed that the metal is stripped all around the main plug as you can see in the picture. So I am down to my backup (purchased before asking if applecare covered power adapters) which has the exact same problems.
I've had problems with my Mac for a while now. First of all, it indicated ram problems with 2 beeps. I later fixed this by moving and changing around modules. It was solved, but now a new problem. The Mac seems to turn on, making its iconic sound for startup, but the screen remains black. After about a half to one minute, the fans go crazy and I have to shut it off. I've tried a few things like holding shift or alt, but that doesn't work as it doesn't even display a white screen.Â
I need to know what to do and I don't really have the time to buy new parts right now. I'm really a windows based pc fixer by the way so I'm new to fixing macs.Â
I'm coming from a good 7-8 years with an old G4, so forgive the ignorance. On that one, I added a PCI audio card to connect with some Altec Lansing speakers with Sub-woofer & simulated Surround sound. It sounded great. hat's your suggestion? Get a similar card for the G5?Or get some new speakers that will sound as good?I don't know anything about digital audio out. Does that connect to speakers, or only tuners?
I got my MBA for 2 days now. Everything works fine except I heard these randomly Click noise coming out from under the power button place every once a while . It only does it once everytime when it happens and the click sound goes less than a second. Is this suppose to be normal?
