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 a problem described by Apple in document Power Mac G5 (Late 2004) 1.8GHz models stop responding randomly.
How can I update the firmware because my G5 1.8 screen is blank? Thought that I could make my G5 1.8 as a hard disk for my MacBook, or I may try to update over the network. Is there a risk of corrupting my MacBook if I try?

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.

On my Al macbook just recently when I hit Cmd-T to open a tab, safari starts to stutter, beach ball, and a distorted screen image (the size of the browser) appears for 3-5 seconds and the tab finally becomes available. what is going on here and how can I fix it? Never had a problem before and I'm using the latest Safari update.
View 5 Replies View RelatedI have a Core Duo 2006 Macbook 2ghz, 2gb RAM, running 10.6.2 and whenever the CPU is taxed for an extended period of time, chances are I'll get some audio issues. What usually happens is that the audio will stutter for a second or so, then change instantly into a heavily distorted 'bitcrusher' output. The only way to resolve this is to restart whatever program is outputting audio. So far, this has happened in both Firefox & iTunes.
View 2 Replies View RelatedAt 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.

Is there a way to set
A) a different sound for when I power on?
B) a sound effect for when I power down?
I already have a .aif file for the latter.
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?

I'm having issues with audio distortion on my BLUE Snowball mic. This happened in GarageBand on my old MacBook running Leopard as well as my new MacBook Pro running Snow Leopard. I've tested mics, cables, and USB ports. Nothing is consistent.
I'm using 3 mics simultaneously. The distortion doesn't not occur in any predictable manner. Sometimes it's present from the start, while other times it doesn't happen until I'm halfway through my podcast. It's not clipping audio, more-so clicks and interference type noise. I've read some people saying there are often issues with audio drivers and USB, and others saying that it's because the power going to the mics from the USB port is dirty.
I have made a movie on iMovie HD (using a Mac Book Pro) and have burned it onto DVD using iDVD. When I play the DVD on my TV or another iMac there is distortion during any rapid movement, e.g. a quick moving arm appears jagged and lined. There is also a slight blurriness to the general picture (the sound is faultless). Why this distortion is occurring?
View 2 Replies View RelatedMy MB started doing this really strange thing where the screen gets all weird and distorted when scrolling. There are photos to show what's going on.
I have 4GB of OWC memory installed, but this was happening before I installed that so I can kind of rule that out.
Has anyone else had this happen, or know what causes it. I've tried all of the usual fixes like a fresh Leopard install and combo updates.
Sometimes, while watching a streaming video on my Macbook, the audio begins stuttering and tearing (that's the best way I think to describe it). Pausing and refreshing the tab is useless, and, usually, closing and reopening the browser is equally useless. This problem is not limited to just one steaming site -- issues occur on Youtube, Hulu, Megavideo etc... For about ten minutes (though sometimes longer), the audio across all programs on my Macbook does not work properly until the problem mysteriously solves itself.

* Every 30 seconds, almost to the second, the audio from the built in speakers distorts and gets slightly louder. This lasts about half a second then goes back to normal
* It only manifests through the internal speakers, it's fine through headphones
* Rebooting makes it go away temporarily
* I've reset PRAM and SMC to no avail
* I've tried turning Time Machine off to no avail
* I've taken it into my local Apple Service Centre, they couldn't replicate the problem, it only seems to happen in my house (every room I've tried it in is the same)
* I bought an expensive power filter/conditioner, this hasn't helped at all
I am having a problem playing some mp4 files through Quicktime. When the video is played in Quicktime (or Pro Presenter 4), portions of the video turn into distorted white blocks that move with the video. It doesn't continue throughout the whole video, but I can't discern when or why it only affects certain portions. It does it every time at those places in the video. I downloaded VLC, and the same exact file plays perfectly fine in VLC and on other computers through various programs. I have only seen this problem on this computer.
Is this a codec issue? How do I fix it? The files in question are mp4 files using h.264 video and AAC audio at 1920x1080 resolution. I can play other mp4s using h.264 and AAC without any problems.
I have only had this problem with one of the companies that we periodically hire to produce videos for us. I'm guessing that it has something to do with the way he encoded the video, but I have no idea what the problem is. It's probably not his fault if it only distorts on this one computer.
Here is what the white block distortion looks like:

I recently updated to 10.7.3 my lion macbook pro system and my sound is muted (I hear that it works only on startup). When i try to modify it appears a grey-black icons of the sound and a disallowance symbol. I try to reinstall the combo but nothing changed. I even try to put an audio jack inside and outside the port but it still doesn't work.

I have latest OS, latest safari & latest flash player installed. However when I go to sites with flash content I get no sound and the audio control is greyed out. (in both safari and firefox) I did get sound before the last os X update. If I go to same pages with my ipad, it uses a different player (i pressume html 5). How can I force safari / lion / webistes to use just html 5 (is this even possible ) and it plays sound fine. I have tried unintalling flash but then I get no video as well.

I recently got my MBP and I noticed there's a issue with headphone audio distortion. When I plug in my earphone or headphone without any sound playing, there's a clear whining noise like zi zi zi sound which is really clear, sounds like old 80s radio noise. When I play the music, of course it was covered by the sound of music but it really bugs me out knowing that I cannot listen the pure sound of my music. The volume of this distortion noise would not change while I turn up or down the volume of my MBP. I asked someone professional, he said it's a famous issue of screen frequency disturbing audio in macbook pro.
View 8 Replies View Relatedwhat I imagined was a documented 8600GT nVidia issue with my SR MBP (purchased in April 2008 without Apple Care, d-oh), turns out to be a different issue altogether. The display gets distorted and it seems as if the LCD needs a v-sync controller. I have posted a video of it here[URL]. If I move the LCD slightly the distortion will go away. But it inevitably returns after a while. It gets unusable for that period of time. Oddly enough I can go hours without this problem manifesting, and then hours when this problem doesn't go away.
My recourse has been to connect an external monitor to the MBP, and it works great that way. So I am pretty convinced that it is an LCD/Cable issue as well. The Genius seemed to believe it was an LCD issue as well, something about the cable being torn or stretched or something. He quoted an amount ~$650 to get the whole assembly changed. Here's my dilemma: this is my work machine, and I can't afford to have it gone for a few days/week. Is there anything I can try at home before handing it to Apple for repair... like try and reseat the cable... I have opened the MBP in the past to replace the HDD. Should I even bother to get it repaired, if I can't fix it myself, or should I just save the money and get a new MBP?

View 7 Replies View RelatedI 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.
View 1 Replies View RelatedFor 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.

Just got a new white MacBook yesterday (MB403LL/A) and have noticed, that depending on a slight change in viewing angle, pastel colors can get really distorted, even appearing as other colors, e.g., light green->gray and light orange to pink. One example would be Google calendar when editing an event. Looking at the screen in a normal position, the background appears gray, but when slumped down in my chair it looks green (the actual color). Is this a normal problem with MacBooks or could my display be defective? I took a couple snaps with iPhone that didn't turn out to hot but illustrate the point:
View 6 Replies View Relatedwhenever I'm listening to music or watching a video after a while the audio will drop out, stutter, or become horribly distorted. If I pause the video or music for a second then start playing it again the output will be okay for a few seconds to a few minutes then stutter again. If I leave it stuttering the output will either eventually go back to normal or just stay stuttering or muted. Once or twice I've got a 'you need to restart your computer' kernel panic error (log attached/linked to below) and twice my computer has seemingly randomly restarted itself.
I know it's not an issue with my connection as it happens on locally stored files as well as streaming media. I know it's not a hard drive issue as I've had the problem across two different hard drives (I used the Migration Assistant to swap my stuff from one HD to another, presumably bringing across whatever causes the problem). I've had it with two sets of RAM as well. It happens whatever web browser (for streaming media) or music/video player I use for local files. If I restart the computer I get a longer period of time before the stuttering starts, and it gets more frequent the longer I leave my computer running - a RAM issue maybe? These screengrabs where taken either during or shortly after the stuttering had taken place. This top output is after a particularly bad stutter: and here is a log following a kernel panic: [URL]
My two previous older macs have been perfect to me, but this new MBP I5 model is giving so many issues lately. Every once in a while, my computer's graphics (I am assuming) goes crazy, and I get this pixelated distortion that's right in the middle of my screen that's about 2"x5" on my 17" screen. This happened just earlier, while I was using Safari. However, even after closing all of the Safari windows down, the distortion will still be there, and will stay there regardless of what I have or don't have open. Logging in and out will fixes the problem, and everything goes back to normal for the mean time. Any one ever experience similar problems or know what I could do to see what's going or fix it?
