Revert of Reland 501823002: Used native deinterleaved and float point format for the input streams (patchset #4 id:80001 of https://codereview.chromium.org/510073002/) Reason for revert: It is speculated that this CL is blamed for crbug/409819, I temporarily revert it to be able to verify it on canary. Original issue's description: > 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. > > TBR=DaleCurtis@chromium.org > > BUG=404884 > TEST=media_unittests && https://webrtc.googlecode.com/svn-history/r5497/trunk/samples/js/demos/html/pc1.html, https://www.google.com/intl/en/chrome/demos/speech.html > > Committed: https://chromium.googlesource.com/chromium/src/+/2c732c000e18a6decd1da8da24e1f5f9e5f16833 TBR=dalecurtis@chromium.org NOTREECHECKS=true NOTRY=true BUG=404884 Review URL: https://codereview.chromium.org/532303002 Cr-Commit-Position: refs/heads/master@{#293156}
