Optical/spdif doesn't exactly send a signal the same way. Clipping happens when your audio out signal gets too high for the device pushing it, this causes lost signal (clipping). I believe spdif follows optical in the sense that the signal doesn't increase in strength as apposed to analog, so you can't really clip. At least, that's my understanding of it as I haven't really dissected audio signals that well.
As far as alsamixer, if you hear clipping you've gone up too far. I normally keep channels set to 90 or something. It actually has a red indicator which would give you an idea if you are pushing the signal too high. I just set everything but master to around 90 and then use master through the DE (kmix ect...) and go with that. You will know if it clips, it's that "distorted" sound you get.Edited by mushroomboy - 1/24/13 at 2:46pm
