Hi there guys. I got a nice quistion (wich I hope you guys can (partly) answer. Ok here goes. I own an imac 400 Dv se with 256 MB 13 GIG and running os9 and osx 10.2.6 Everything about the mac worked fine until 1 day the speakers stopped working.I thought that was rather strange but I just got my headphones out and plugged those in But after a while the signal coming through the headphones got less and less. If you bumped the connector it would work for a few mins but after that - silence. So the sound part on my imac is officialy dead. I thought maybe a short circuit somewhere? Would it help if I replace the little logic board behind the front headphones connectors? When I start it up I can hear a few very soft clicks through the speakers. Is there another part of the main board dedicated to sound? Thanks if any1 has some great ideas about getting my mac working with sound again!
