output zeroing
2014-01-03audio_mix: fix zeroing output channels in certain casesAnton Khirnov
Specifically, when the corresponding input channel exists and its matrix column is all-zero (which is necessary for zeroing the output), the matrix column must be removed from the matrix. This is not done currently, so the mixing code would end up using uninitialized pointers from stack. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind
2014-01-03audio_mix: initialize the data pointers to NULLAnton Khirnov
This should make it easier to catch problems where some of those pointers are used uninitialized, since reading from NULL should always crash, while random numbers from stack can turn out to be valid pointers, so random memory may be silently overwritten.
