Funny thing, this: suddenly my PowerBook refuses to play sound. Nothing comes out. I can adjust the settings as much as I want - no external sound, no internal sound. Not even the system start gets its sound - everything is mute. Resetting Open Firmware and resetting Parameter Ram didn't help either.
I had already had strange phenomena with the sound: every time the internal sound wanted to make the system block briefly at the first attempt. As if the sound chip had some kind of problem. But that should be noticed during the hardware test of the motherboard - nothing, the test runs smoothly through. Damn. Ok, I have Apple Care for such purposes and will simply call them and then probably at some point take my PowerBook to the dealer for repair - but in the meantime I won't have a computer at home and that's annoying. Ok, I have the company Mac and I'll probably make it ready in such a way that I can simply carry it back and forth between home and work (a Mac Mini is luckily not much to carry), but it's somehow annoying when something like this happens just because of stupid sound stories. But I also don't want to give up feeding the system from iTunes on the computer ...
