Awful static on apple tv startup

I recently purchased the apple tv (1080p version) to hook up in my room to stream music to my speakers.
I currently have the apple tv setup through hdmi to a computer monitor and optical to my receiver on my speakers.
Whenever i awake the apple tv from sleep i get an awful static noise coming through the speakers for 5-10 seconds.
On further investigation i realized the static cuts off as soon as the video signal (through hdmi) is received by the computer monitor. Thus when i startup the apple tv from sleep without having the computer monitor on the static lasts quite a bit longer.
All the cables are fine, it's not the cables that are the issue.
What has fixed the issue is if i completely unplug the hdmi cable from the apple tv thus leaving only the optical audio cable to the speakers. When i did this i get no static, but i dont want to run to the device to plug in the hdmi whenever i feel like using the screen.
I called apple support and they were pretty unhelpful. Anyone have any suggestions?
Sorry for the long write up, thanks in advance!

Have either of you guys tried configuring the ATV3 to use different audio settings? If you set it to a fixed output option, hopefully you would eliminate any glitches due to the negotiation implied by using HDMI, which could conceivably mess up the optical output, too.

you're right, wouldnt hurt for me to try ..
think it might have anyhting to do with the fact that the video cable is actually an hdmi - dvi cable?
probably not right? just fishing for someting !
Negative on the HDMI/DVI cable being a problem. HDMI is fully backwards compatible with DVI, and it's a straight through connection (no "converter" is involved) and cannot be an issue in and of itself. It's something that can be expected to work fine. What can be a problem are the usual problems associated with HDMI and cables in general, e.g. handshaking issues, HDCP and other incompatibilities, bad connectors, etc, along with other bugs in the connected devices. It could very well be your computer monitor is providing EDID info that the Apple TV doesn't like for whatever reason, or it could be a bug in the handshaking on one or both ends, etc, and it would still be a problem if your TV was HDMI, all other things being equal. This is very common in HTPC circles, and if you really want your eyes to glaze over, google /site:avsforum.com edid override/. This won't help you with the Apple TV, but it'll familiarize you with actual problems as you've already gotten some FUD about the DVI/HDMI cable and will almost certainly be receiving some more in this forum now that I've pointed it out. It's pretty much unique to this forum, so just ignore it.
In any case, if your intent is primarily to use the ATV as an Airplay bridge to your stereo, and you have an iPod Touch, iPhone, or iPad, you might find the Remote App's 1' interface far superior to the ATV 10' interface for selecting music in iTunes. I know I do. Then you don't need to connect the ATV to your monitor except to change settings, which is essentially never, and you've already discovered that it doesn't produce static that way. That's the way I use my ATV2, and it's what I bought it for, but FWIW, it didn't produce static when I briefly connected it to my NEC monitor with a DVI/HDMI cable and optical to my receiver for testing after I made the mistake of allowing my ATV2 to update itself to 4.4. Maybe this is a new ATV3 problem or an iOS 5 problem. I wouldn't know, as I reverted to 4.3 back when it was still possible and won't update ever again as long as I'm using my ATV as a pure Airplay audio bridge and having no problems with it.

Intel Imac won't get past Apple on startup

One of our 17" Intel Imacs (early to mid 2006 model) will not get past the Apple on startup. I have done the following:
1. Replaced the ram. No luck.
2. Zapped the PRAM. No luck.
3. Reset the SMC. No luck.
4. Tried booting from several CDs including disk warrior. No luck.
5. However, I was able to run the Hardware test from the system disk. It found no problems the several times I ran it.
6. I was able to mount the drive using Target Disk mode. I then ran diagnostics on the harddrive. Fixed some things, but nothing major. Still won't boot.
7. I tried the opposite approach and tried to run the machine using the other machine in Target mode. No luck.
8. I downloaded firmware, created a disk per apple's instructions and tried to run it. No luck.
I think that is basically it. I've been able to backup all the data and was going to reformat the harddrive, although I don't see how that would work considering that the machine won't boot up from either a CD or another drive in Target Disk mode.
I'm thinking this machine is a goner. Any other ideas would be much appreciated.

Have you tried the diagnostics? Insert the original OS X Installer Disc One that came with the computer and restart the computer. After the chime press and hold down the "D" key until the diagnostic screen appears. Run extended diagnostics and not any error codes reported.
If you cannot boot into the diagnostics then take the computer in for service.

Red static using Apple's mini-Displayport to DVI Single Link adaptor

Here's the problem :
The adapter from Apple I got is the 30$ (or so) DVI-D Single Link (nine pins active on the side with six pins non-active in the center).
My Dell 2408WFP monitor got two DVI-D Single Link connectors.
I did my test with two different cable : one DVI-D Single Link and one DVI-D Dual Link. Both cable are working just fine since I can hook either my older Macbook Pro Core Duo or my PC to the monitor using them.
But when I 'm trying to use my new Macbook Pro Unibody 13" with the mini-Displayport to DVI adapter I always get red statics : one pixel dots flickering randomly all over the screen. The picture is there, though, and my computer is able to recognize the display and its native resolution (1920x1200). Sometime, the display seems to lose the signal and shows only white noise.
Any idea, similar experience?

Thanks for everything,
P.

Problem solved here, really. Nothing to do with Apple. Everything to do with Dell.
So I got a replacement monitor (a second one) from Dell regarding another problem with the Displayport connexion. It fixed this problem. I then tested the same mini-Displayport to DVI adaptor on this new replacement monitor : works flawlessly. No problem whatsoever. No static. No suddenly going in sleep mode. No random disconnection. So the problem was the monitor : EDID profile, maybe firmware. See below.
Here are more details which I got using SwitchResX. I hope it can help others for diagnostic.
The monitor that was ALL wrong was : a Dell 2408WFP, EDID version 1.3, product code 10912 (2AA0) (A02A) (which means, I think that it was REV A02A : you CANNOT rely on what's written on the sticker on the back of the monitor for that info especially when you get a replacement monitor, use SwitchResX).
The new monitor that is WORKING (with everything : Diplayport connexion as well as mini-Displayport to DVI adapter) : a Dell 2408WFP, EDID version 1.4, product code 11168 (2BA0) (A02B) (so I guess is REV A02B).
Notice the difference in the EDID version AND in the REV version.
If you have a Dell monitor, same model (2408WFP) and are experiencing problems with your connexions, check those info, call Dell for a replacement.
Thanks for all your feedback and suggestions. I'll post this on Dell forum as well.

Black Curtain during Apple/Spinner startup

I've been struggling with this for a few days, watching posts in this forum and trying things out, but nothing seems to work.
Upon startup, my PB gets the "Black Curtain" error message after a few seconds into the grey Apple screen with the spinner. What's odd is that it does this whether it is starting up from the internal HD or my Leopard disk, and when I tried booting a second machine from the PB hard drive in FW Target mode, it got the same error, though not when loading from the Leopard DVD in the PB drive.
I've managed to get it to start up in "Safe Mode", and that seems like progress, and I can start it up from the DVD in Safe Mode, but that didn't seem to be a lot of help. On another post's recommendation, I tried deleting the boot kernel extension thingy, assuming it was corrupted, to no avail. Because I had everything backed up the night before this started happening (THANK YOU TIME MACHINE) I have no fears for the data on the PB, so I tried completely reformatting the disk while reinstalling Leopard from the DVD in safe mode.
What has all of this gotten me? An essentially virgin install of Leopard on an empty disk that gives me the same error I've been getting this entire time. I fear that this is the logic board giving out, but it doesn't seem like the right symptoms, and I'm trying to exhaust every possibility before going to the Apple Store and plunking down my $319.
Any suggestions?

Macgregor Justice:
I gather, from your description, that you refer to a Kernel Panic. If you do a search you will find plenty of reading material.
There are two basic causes of KPs: software and hardware. Theoretically the reformat should take care of the software angle, although the ability to boot in Safe Mode raises questions in my mind.
From the hardware angle, I would not jump to the conclusion that it is logic baord. The Airport card is a frequent offender, as is RAM. I suggest that you begin by booting from the Apple Hardware Test disk that came with your computer, and running all tests in a loop by holding down Command + L during the tests.
Good luck.

T61p has awful static/clipping from left speaker

Hello all,
I just got a T61p (6457MM1) today and love it (well, I love it after I turned off the "Beep" driver that was making the keyboard beep every time I typed "around".)
The only problem with it is that the sound out of the left speaker is, well, crap. It clips, there's a static sort of sound, it generally sounds awful.
I have the latest version of the sound card drivers as listed on the Lenovo site. I have run Windows Update and installed all of those.
I searched the Internet and found some people [http://forum.notebookreview.com/showthread.php?t=261186] who are reporting this same problem and that it occurred due to a BIOS update. Given that this system is brand new (and that I've run through the ThinkPad updater too), I'm confident it has the latest BIOS.
Is Lenovo aware of this/is there something I can do?
The easiest way to hear the problem is to open the Sound Control Panel. click "Configure", then click Test. You can hear that in the test tone, the left speaker sounds substantially worse than the right. This occurs at any volume.
Also, I wanted to set up the password reset service questions, in case I ever forgot my BIOS supervisor password. I set it up in the BIOS, but the help text then says to run the "Create Recovery Media" program from Windows? I ran that program and made the CD, but it didn't ask me to set any questions and if I look in the BIOS again it still says the status of the password reset service is "In Progress".
I wanted to burn a set of recovery discs, but I can't, every time I try I get an error message that says "The files required for creating the rescue media cannot be found," then "An internal error has caused this process to fail." I am talking with my sales rep to try to get a set of recovery discs sent to me since the program to make them isn't working.
Is there some other way to establish the password reset service questions?
Thanks in advance.

Hello,
I own a T42p since 4 years now and has always been working like a dream, except for a harddisk failure. Since I did create a backup to CD/DVD I was able to restore my Windows XP environment without much trouble. I subsequently updated my laptop with WIN-SP3, updated BIOS etc etc, and updated all Thinkvantage software (e.g. RnR 4.2, Client Solution 8 etc etc).
I also 'updated/repaired' the MBR, based on a Lenovo defect based on the same error, but didn't solve the issue.
Problem: I have not been able to create a new complete CD/DVD backup set. The error message from RnR is "The files required for creating the rescue media cannot be found," then "An internal error has caused this process to fail", as StarmanDX excperienced.
I can continue to create the backup, but I cannot create the corresponding boot disk.

Apple Gray Startup screen changes color before going to desktop.

Hey guys,
Since I upgraded my macbook air to lion last summer, the startup is a tad slower because the gray screen with the apple logo changes from a blu-ish gray to a yellow-gray before going to the desktop. I do not have this problem on my iMac. Anybody have any answers?
Thanks so much!

I find this topic kinda funny. several answers and NONE of you guys mention that the spinning wheel is supposed to be there and completly normal, it appears on every mac and I'm 100% certain it appeared on your mac before as well.
the spinning wheel is supposed to be there, it's nothing to worry about it's the regular OS X boot up working indicator. it even appears on the new macbook airs with flash storage built in, where boot up takes about ... 8 seconds or something.

Static from speaker on startup

I have an iBook that I recently replaced the hard drive in. Everything works fine now except I have static coming out of the speakers on startup, and anything that requires the speakers to activate, especially the right one. The sound is fine when using headphones. The one thing I have noticed is when the computer is idle and I plug in the power cord the static from the speakers starts up and the volume control does not have any effect. Before I take this apart to see if there is a ground or a wire out of place does anybody have any ideas?

Greetings
I ended up taking the iBook apart and discovered that while lowering the top case and connecting the three plug-ins the speaker wire moved slightly and the insulation on the wire got pinched and exposed the copper wire. This must have picked up static from the internals and caused the problem. I teased the two wires to the right speaker apart and wrapped them. I then put a small piece of Kapton tape to hold the wire in place when lowering the top case. Everything is now working great and my son is happy. Thanks for the ideas.

Static on Apple TV

I have a 3rd generation Apple TV that I've had since December 2012. When I tried to use it today, I found that I'm getting static through the audio side, even when in the menu. When trying to play something, it's so bad that you can't hear any of whatever is playing. This affects everything I tried: Netflix, Youtube, SkyNews, and even streaming music from my Mac. This basically makes the device totally useless, so I hope someone here has a fix. BTW, I tried resetting and power cycling the Apple TV without effect.

Actually, I don't have it connected to a TV for audio. It's connected to a soundbar. I suspect it is the Apple TV, though, because everything else going into the soundbar works fine. The Apple TV is the only thing that exhibits the problem.

Red apple on startup

I noticed that when I upgraded to 10.9.3 that when powering on my MacBook Pro-retina, that the Apple splash screen is now flashing a red apple insted of the usual grey.
Is this normal? If not, what does it signify?
Thank you!

You're not alone. It's happening to my PowerBook Pro running 10.9.3, as well.
Anyone else seeing this change in startup behaviour after updating to 10.9.3?

Apple at startup... but nothing else.

When I startup our Mac Mini server I get an apple logo. Eventually the gear appears underneath it and then all I'm left with is the apple logo again, and there it stays.
I've tried shutting down and restarting while holding down the d key. The results are the same.

The repair did not resolve anything.
An attempt to download the OS X Server software failed on numerous ocassions due to Apple's iTunes not accprting my Apple ID.5 calls to Apple Care did not resolve the issue. I figured out a workaround and we're back up and running, this morning!

IBook G4 1.2. rarely gets past the apple timer startup screen

iBook G4 1.2. After a few minutes on the apple timer screen all we can get is a blue screen sometimes. Harddrive OK when opened in target mode and has been erased and 10.2 successfully reloaded. Does anyone know what the problem might be. Thanks Stephen

Will it boot in Safe Mode?
Mac OS X: Starting up in Safe Mode - http://support.apple.com/kb/HT1455
What is Safe Boot, Safe Mode? (Mac OS X) - http://support.apple.com/kb/HT1564
Safe Boot takes longer than normal startup - http://support.apple.com/kb/TS1884
You can view SMART status using the Get Info menu item in Disk Utility but sometimes it doesn't work for external drives (I don't know if a drive in another computer is considered external in this regard).
When you erased the drive did you try writing zeros once in security options? This kind of stress tests the drive and will force it to have a look at all sectors rather than just saying it removed all reference to the files so the drive is fit and ready for use.

Gray circle instead of apple at startup

i started up my 20" imac today and at first it came up to the startup screen with a circle with a slash instead of the apple logo. i turned it off and on and it loaded normal. im just curious to know what might have caused this, since this is the first and only time its happened.

See: Mac OS X- "Broken folder" icon, prohibitory sign, or kernel panic when computer starts

Mac stuck on the grey apple screen startup? Follow these steps to re-boot....

So today I had a little scare with my Macbook. It was stuck on the grey apple startup screen with the loading icon. Switching it on and off did nothing and neither did waiting. I did a lot of browsing to try and find a solution but all the forums ended in 'looks like thats the end of my mac' or 'I think i've lost everything' or 're-install Os' blah blah etc. I DID NOT WANT TO LOSE ANYTHING!!! and I'm guessing neither do you! Ok so enough talking, in the end I found a solution which worked perfectly for me and I did not lose anything!!!!!:
Step 1
If the Mac is on switch it off.
Once it is off, switch it on again but this time as soon as you press the power button to switch it on, hold down the Apple cmd key + S.
Hold this down untill the 'safe boot' screen appears.
A black screen with white writing should now come up.
Step 2
Once the screen has loaded, at the bottom type:
/sbin/mount -uw /
[press enter]
then type:
chmod 775 /
[press enter]
then type:
exit
this re-boots the mac. As soon as you have done this the mac should load up again as normal!! Voila!!!
Hope it helps!

Someone suggested this to be risky. worked for me but DON'T DO IT WITHOUT RESEARCHING FIRST and if in doubt CALL APPLE!!!!!

Awful experience in Apple Store...can't find how to complain

Hi everyone.
I had a terrible experience in an Apple Store tonight and I'm not sure where to go on this website to get it rectified. Maybe someone can point me in the right direction.
I had a Genius Bar appt at 7:40 to look at my phone. I went around 7 because I had a little shopping to do first. I went to the store and asked if there was an earlier slot I could take. The gentleman said I could have a seat and the girl would wait on me. I wasn't sure who to sign in with so I went to the bar. I had my mother with me who is on chemotherapy. We both sat and waited. We figured out we were sitting in the wrong place and after asking the check in guy again, sat at the right table. The girl who was working on the phones said nothing to me or my mom and kept working on everyone's phone. I told her I could come back at my appointment time, and she rolled her eyes and said "you can wait".
After about 20 minutes, she took a person who came to the table after me-and then I asked to speak to a manager. The girl laughed, walked in the back and pointed to my mom and laughed with a coworker, and came back with a new phone for someone.
We waited ten minutes and no manager. I tried to ask another worker, but they must be trained to ignore you. We ended up leaving because my mom couldnt stand that long. Now I am out the forty mile drive, the gas, and the time it took for me to wait for a college kid to decide they didn't want to hep me because I was with an advanced stage cancer patient.

Sorry hear about your bad experience! Go to http://www.apple.com/retail/feedback/ to give feedback to apple. Have a great day!

Apple TV - Startup Assistance

I just ordered Apple TV having just recently crossed over from the darkside (pc's). Is there a site on how to setup and use Apple TV with all Mac devices. Thank you.
