Description
It looks to me as if there is a potential for arithmetic overflow in the mixer with some of the channel types. In reality I've only managed to provoke a few popping sounds when cranking up all the volume controls to their maximum setting, but I still think it'd be safer to use clamped_add_16() than to just add the sample to the buffer and assume it will work.

Done.
BTW, the clamp_add_16 function is quite crude, it cuts of "hard", a better implemention would do it slightly "smoothed", in order to reduce artifacts a little.
