[OE-core] [PATCH] speex: Scale float input when FIXED_POINT is defined

[Fahad Arslan]

From: Fahad Arslan <Fahad_Arslan at mentor.com>

When Speex is compiled with FIXED_POINT defined, it scales float
input to +/-32768 instead of +/-1. This was being missed at one
point causing the input to the resampler to be zeroed. As a result
there was no audio output.
