Does not function properly when compile for arm64

[liangxiu]

I used G729 codec in my VOIP App, when the app target only armv7, it works fine. The Callee can hear my voice clearly. Then I turn to arm64, the callee no longer get my voice clearly. I record the input voice raw data before and after G729 codec both on armv7 device and arm64 device on the Caller side, and then convert the G729 encoded data back. I find the converted back voice from armv7 device is much better than arm64 device.

Which arm64 device are you testing with? Is it possible you could submit a pull request to fix this?
