Hej igen,
kanske följande kan ge oss svaret. Om jag fattar det rätt så är det en speciell "adapter" som behövs för ett antal hundralappar. (billigt Apple anser jag - skicka med…)
" Reader Replies on Intel CPU iMac Audio: (most recent first)
Audio Output Jack Compatibility
Most reports here commented on optical audio cables, advanced features, surround sound, etc. - a reader recently wrote on problems using analog speaker/headphone connectors.

"I just checked with 3 new iMacs (20in and 17in). You cannot insert the 3.5mm audio jack in the audio port of the iMac. I tried 3 different jacks to no avail.This results in not being able to use external speakers or headsets. Funny this has not come up before.

I've not seen a new Intel CPU iMac yet but the Apple iMac specs page notes a "Headphone/optical digital audio output" and I checked Apple's iMac support page and downloaded the iMac (early 2006) User Manual (PDF). Page 55 covers connecting audio devices and says:
" Using Audio Devices
Your iMac comes with built-in stereo speakers, a combination headphone out/optical audio out port, and an analog audio line-in port.
Headphone Out/Optical Audio Out Port
Connect a pair of headphones to the combination headphone out/optical audio out port and listen to music without disturbing anyone around you. You can also connect your iMac to an AV receiver using an optical audio cable with a miniplug."
Apple's 'Mac 101' page on connecting audio devices mentions a std 1/8in stereo mini plug. (Although 3.5mm is larger (appx. 0.138 inches) than 1/8in (.125), I mic'd a jack here and it measured .135.) I also wrote a reader with an Intel iMac to ask about this and he replied:"

" It only happens with line-out connected devices. Built-in speakers have no issues. I'd say it looks like some audio driver problem instead a hardware one."
