Used native deinterleaved and float point format for the input streams.
If we call GetProperty of kAudioUnitProperty_StreamFormat before setting the format, the device will report kAudioFormatFlagsNativeFloatPacked | kLinearPCMFormatFlagIsNonInterleaved as the native format of the device, which is the same as the output.
This patch changes the format to use kAudioFormatFlagsNativeFloatPacked | kLinearPCMFormatFlagIsNonInterleaved to open the device, so that we will avoid format flipping back and forth. Hope this optimization will help increase the stability of the input audio on Mac.
