I've tried googling this but without any success. Everyone seems to be telling stories like the one below:
So tonight I was about to watch a new promotional video, but I forgot to turn down the volume before I put my headphones in. As soon as they're plugged in, the volume jumps to 100% and I damned near blow my ear drums out.
It was simple on my DELL. Whatever volume you set it, it'd stay there despite whatever you plugged into the headphone port.
However, with OS X it seems you can set the volume to 20%, but as soon as you plug something into the headphone port, the audio will jump to a preset volume. For mine it seems to be 100%.
Where is the option to correct these? I'd rather have the defaults set to 10%...
I can confirm on a MBP running OS X 10.6.7 that this is still happening. Has anyone found a solution?
