I have a MacBook Pro C2D and am trying to record some LPs to my computer. I have the record player hooked up to a regular home receiver with the output of that receiver (tape out) going straight into the input jack of my MBP (via a Y adapter cable). What is happening is the signal is too strong and is being clipped. But when I go under System Preferences -> Sound -> Input the slider for input volume is all the way to the left. I can't go any lower. It seems like this is a limitation of the audio driver, but I can't understand why the default setting would be for such a high gain. Has anyone done this successfully? If so, could you share what you used and how you did it?
