Fix the warning by setting those xxx_shift to 0 instead. Note that since the code explicitly checks .mono_shift >= 0 and .fs_shift >= 0 before using them in '<<' operator, those two members are not set to 0.

Fix the warning by setting those xxx_shift to 0 instead. Note that since the code explicitly checks .mono_shift >= 0 and .fs_shift >= 0 before using them in '<<' operator, those two members are not set to 0.
