Ivo,

Please, take a look.

The reason that the checksums are changing is as follows: NetEq has its own
table of pseudo-random numbers. Numbers are extracted from this table (from
start to end, and then starting over again) when generating CNG, and when
producing packet-loss concealment data. With this change, the number of values
taken from the table during CNG is increased from 32 to 48 samples, which alters
everything.

LGTM.
