So, another iBook. Left speaker does not work and what is more surprising is the fact that right speaker does not mute when headphones are plugged in, sound is heard from both the headphones and right speaker. With headphones both channels work and it is not just balance setting being all to right. I have tried all the resets, including those in open firmware. This machine already has defective AP slot so I removed whole card and use USB dongle. I wouldn't be surprised if this audio thing is just another HW problem" Any thoughts? Edit: 2005 12" machine.
