[meta-freescale] [meta-fsl-arm][PATCH v5] pulseaudio: Add PulseAudio configuration

That is interesting. I assumed the Speex one is a pretty good quality 
resampler, at least unless you use a really low quality value (4 or 
lower). I can imagine though that the most recent ffmpeg resampler (IIRC 
they were writing new ones) is faster and has a better quality, given 
that Speex is pretty much dead. Nice to know.

Rephrase it to "use the ffmpeg resample instead of the speex one, since 
the ffmpeg resampler gives better quality".
