Subject: echo-cancel: Ensure correct handling of endianness
X-Git-Tag: submit/2.0-panda/20130828.192557~947
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=6897217d26066353492b6b906ddbaa58c2dae054;p=profile%2Fivi%2Fpulseaudio-panda.git

echo-cancel: Ensure correct handling of endianness

The adrian module was using home-brewed endianness conversion instead of
the appropriate mactos, and speex assumed a little-endian host. This
fixes both of these.
