Binary package hint: pulseaudio

using the speex-float-1 resample-method in pulseaudio provides poor
performance on armel: floating point operations are expensive in part
due to the use of the softfloat ABI, and in part due to limited
implementation on most hardware (many ARM solutions have dedicated
hardware to handle many of the tasks often handled by floating point
accelleration on other architectures).

To address this, please use the speex-fixed-1 resample-method.  When
doing so, performance is further improved by reducing the default number
of fragments from 8 to 2.
