it potentially changes the audio data going through PA; not that one
should depend on a precise float32 value :)
might bite people doing automated testing

it potentially changes the audio mixing; audio may sound differently

speex-float-1 is quite noticeable on ARM

maybe nobody cares except me; the implication is that the EC module is now
more flexible and supports e.g. a 4-channels microphone signal going into
the echo canceller (say for noise reduction) yet output and playback
(towards the application) are single channel; no EC implementation
shipping with PA needs this for the moment
