Just wondering if anybody else has been experiencing problems with headphones connected to a 600MHz ibook. In addition to constant static on the line I get a random, but persistent, high-pitched screeching noise. It's not that loud, but it is quite annoying.

I know the headphones I'm using are good since I use them in other devices and never have problems, so I'm wondering if this may be bad shielding or a result of the combined audio/video port just being a bad idea.

I'm loathe to have to send this otherwise great computer off to Apple for repairs, so I'm just looking for others who have had the same, or similar, problems.

Thanks.

It sounds like you will probably have to send it/bring it in for service.. Before you do that (and I know that you said you use these headphones in other devices, etc), I would suggest using another pair of headphones on your iBook just to rule out something funky going on with 'em...

I just came here to post some headphone woes as well. I'm running 10.1 on my ibook 500. When I plug my headphones in / take them out (sometimes, not always) the screen will go blank for just a sec. then return to normal. This happen to anyone else? Maybe I should update to 10.1.1. Thanks.

I have had excactly the same thing happening on my new iBook 600 with 10.1.1 installed, so I don't think you upgrading to 10.1.1 will solve the problem...

Hope Apple will get rid of this bug in later system upgrades.

BTW, on my iMac 400 DV, everytime i pulled out the phono cable (going from my iMac to my amplifier) from the audio out port, the screen just died. The only solution to get it back was a forced reboot. Strange...

Whan you plug in your headphones look in the control strip and see if the monitor resolution also says "simulcast in ntsc/pal" (sp?) if it does it thinks your headphones are the av cable. if not send it in

i have an ibook dual usb 500mhz and I have the same problems listed above with my head phones too. Thing is, I can even hear it make specific noises to my clicking the mouse, say in Limewire or in IE. I thought it was random, but sure enough, I click and then a small and very tiny little "pizzop" sound and then I'd do it again and again, same result...just thought I'd share.


I got this ibook at the beginning of september 2001.

I had my first and only kernel panic when disconnecting my headphones during X.1 startup. There is definetely something fishy going on.

I had similer probelms with my 500mhz when I got it. Also the same with a G4 533 Digital Audio. If you don't use it, try disabling the Fax software. Thats was the problem on the G4. Apparently FaxSTF was causing those ones. Mine doesn't do it anymore, I guess I must have disabled the Fax software.

I have the exact same problem with my new 600 W/30 GIG HD. Every time the hard drive is accessed, there is a faint and high-pitched squeeling noise in the headphones. I sent it in to apple, I hope they fix it.

As for the screen going blank while plugging in the headphones, this is because the same jack is used for the AV video out. If you plug your headphones in too slowly, you make connections you probably shouldn't be making and it thinks you want to display to an external monitor etc...

I am loathe to send my ibook in for service since I absolutely require it everyday and have no replacement on hand. But I do believe that this problem is a hardware issue. I too realized that the high-pitched noise comes whenever the hard disk is accessed, so it probably has something to do with insufficient sheilding on the A/V jack or something of the like. I though that it might be specific to OS X, but when I tested that in OS 9.2 I still got the squealing.

Anybody have some advice on what course of action I can take? I mean, how long would I have to wait to get the laptop back from Apple?

I have the same problem with the Blank/Grey screen when plugging in the headphones or unplugging them. Really bugging but I find it doesn't happen all the time. I don't think it has ever happened when I plugged in while the Finder was active.

iBook 500 DVD, 384 ram and Mac OS X 10.1.1

cheers, tobs

I've had this happen occasionally with my iBook 466. It Seems to be the computer changing resolutions. The headphone jack is the same as the A/V jack, so the iBook think you are unplugging the A/V cable. Its not anything to worry about though. If the iBook thinks it is the A/V cable, that could explain the sounds since you would be getting the video feed with the sound.

Just my two cents

I had similar problems right after I got my iBook 600 combo. I got the gray screen when plugging the headphones in and unpleasant noises because it thought it was the AV cable, not headphones. After a while the problem went away and I haven't noticed it doing the gray screen or thinking my headphones are AV cables anymore.

Back when I thought it was always going to noticed headphone insertion/removal I bought a small right angle adapter at Radio Shack so that I could just leave that plugged in so the iBook wouldn't noticed plugging and unplugging headphones. Once the problem went away (a day or two) the adapter wasn't really necessary anymore.

I have no problems with the headphones output (sounds beautifully, unlike my shitty MiniDisk player).
I don't suffer from insanity, I enjoy every minute of it.
