I thought the epocolypse was coming.
Wow, thank god for this forum.
My speaker on my iBook G4 cut out the left channel completely between two songs in iTunes, at first I thought it was my sterio because it's an older set that has fragile wiring. Then I diconnected the Y Cable from the minijack and the iBook speaker wasen't working I almost went crazy.
I called Apple Canada and the lady was all "Well, your 90 day telephone warrenty is up, it'll cost you 59$ CND"
Then I found this 2nd from the top search on google for "ibook speaker dosent work"
Thank god... I was thinking about sending it in for repair, and being without it. I really hope Apple fixes this in a later patch or update maybe we should tell them about it they may not know.
